Issue 5 May 2000 Introduction 1 - 1 1 Introduction Product Summary This product manual (Select Code 157-005-104) describes the H569-445 Secondary DC Power Distribution Bay. This unit is also known as a Battery Distribution Fuse Bay (BDFB) or a Battery Distribution Circuit Breaker Bay (BDCCB). The H569-445 series bay is shown in Figure 1-1. It serves as a secondary fuse or circuit breaker distribution center for dc power delivered from a central office battery plant to the using equipment. It provides space-efficient branch loading for distributing +24, -48, or ±130 volt dc power, or combinations of these voltages from different battery plants. (BDCBB versions of the Distribution Bay do not offer the ±130 volt dc option.) In many applications, telecommunication equipment requires power redundancy from the battery plant. A BDFB or BDCBB provides this redundancy through the use of multiple load buses. The H569-445 is a cabinetized distribution system that supports these applications by providing up to six distinct load buses for the 7-foot cabinet or up to eight distinct load buses for the 9-foot cabinet. Each load bus has a rated current carrying capacity of 600 amperes. Each load bus may be configured to include one or multiple fuse or circuit breaker panels. Each fuse panel provides 20 mounting positions that may be equipped with either WP-92461 cartridge fuses that range from 3 to 70 amperes and/or GMT fuse modules containing three fuses ranging from 1/2 to 5 amperes. Fuse panels may also be equipped with 70-150 ampere TPL type fuse blocks. Each circuit breaker panel provides 20 positions for circuit breakers ranging from 3 to 100 amperes. Additional features include: digital meters; remote monitoring capability for alarms; multiple cabinet heights, and optional 2-hole ground bus arrangements mounted either in the cabinet or external to the cabinet on a cable rack. These options and many more provide greater flexibility for customers with different distribution requirements.

2 - 8 Product Description Issue 5 May 2000 Load Bus Arrangements The bus bars used in the distribution bay are sized to provide a rated current carrying capacity of 600 amperes. (A minimum of two 750 KCMIL feeder cables are required per shunt for currents larger than 500 amps per shunt.) A load bus is defined as one or more fuse or circuit breaker panels protected by a single circuit breaker or fuse at the battery plant. Cable from the battery plant is terminated at the load connection mounted on the dc panel.Group 20 provides load connection points for two load buses. Figure 2-5 shows this Group 20 load connection. As Figure 2-5 shows, battery is bused across a load monitoring shunt to each fuse/circuit breaker panel. Note: Group 20 provides connection points for two side-by-side loads. If fewer load buses are required, it is possible to connect fuse or circuit breaker panel battery buses together using a Group 40 bus bar link. This feature is shown on Figure 2-5. This may be desirable for two or four load distribution bays where more than twenty fuse or circuit breaker positions are required for a single load. Only fuse or circuit breaker panels mounted above or below one another may be connected, i.e., panels mounted on the left side of the cabinet cannot be joined to panels mounted on the right side of the cabinet. Remember that the 600 ampere capacity per load bus applies even if multiple fuse panels are connected together. Note: Group 40 provides two bus bar links, one for the left side and one for the right side. Note All bus bars used in this product are copper with a solder plate finish. Bus bars do not require buffing or the application of NO-OX before connection to terminal lugs or other bus bars.

2 - 10 Product Description Issue 5 May 2000 Discharge Return Bus Options Two optional discharge return bus options are available for terminating fuse or circuit breaker return leads: (1) Bus bar returns located in the distribution bay (G-61 and G-61A) or (2) A return bus located outside the distribution bay on a cable rack. The first option involves a bus bar arrangement similar to the battery bus connection scheme discussed in the previous section. Discharge return cable from the battery plant is terminated at the top (or bottom) of the cabinet adjacent to the battery input cabling on Group 61 bus bars. Group 61 provides bus bars to connect the battery plant discharge return cabling to Group 61A bus bars mounted on each fuse or circuit breaker panel adjacent to the fuse blocks or circuit breakers. This option is shown in Figure 2-5. Internal returns offer the advantage of paired leads directly from the fuse or circuit breaker and eliminates the need for identification tags on each return lead. The discharge return bus is designed for terminating 1/4 inch double hole terminal lugs. Note: Group 61 and 61A provide two bus bar links, one for the left side and one for the right side. The drawback to this cabling scheme is that you are limited to 600 amperes capacity due to the size of the bus bars. A second concern is the potential cable congestion resulting from twice the number of leads in the distribution bay. For these reasons, the internal discharge return option is recommended only for applications with smaller ultimate capacities. For most applications, the external return bus option is recommended. The external discharge return bus bar options are shown in Figures 2-6 and 2-7. The external bus is mounted on a standard 15 or 20 inch ladder type cable rack. Options 848258679 and 848258687 are rated for 2400 amperes of current. Option 848258679 provides the first bus bar and the cable rack mounting hardware. Option 848258687 provides a bus bar, the connecting bus bar and insulating standoffs for stacking additional tiers as required. The ED83019-50 G1 bus bar assembly has a 1200 ampere current rating.

Issue 5 May 2000 Product Description 2 - 15 Digital Meters and Monitoring Shunts As discussed in the previous sections, there are six possible load buses in the 7-foot distribution bay, three per side, and eight possible load buses in the 9-foot distribution bay, four per side. Each load bus is equipped with an 800 ampere shunt per Group 20. Group 20 provides two shunts, one for the left dc panel and one for the right dc panel. Shunts are provided to determine actual current use and the remaining capacity of each load bus. They can either be monitored externally by other office equipment or in the distribution bay with a digital meter. Two digital meters are available for monitoring the shunt currents and the panel voltages: G-70 and G-71. G-70 The G-70 digital meter monitors only the 800-ampere shunts (see Figure 2-8. It is available for 24-, 48-, and 130-volt systems. The shunts are wired to the meter through a rotary switch, enabling the user to select any of the possible load buses. The meter is powered from the first equipped panel position. Note: If the power is lost to the first equipped panel position, the meter will lose power as well.

Issue 5 May 2000 Product Description 2 - 17 ED83127-30 Fuse Panels Groups 30A-30D Each fuse panel is equipped with 20 single position fuse blocks for TPS fuses. If alternate fuse blocks are desired, they can be ordered separately and installed in the field. Spare fuse holders are supplied with the fuse panels. The Group 30A-30D fuse panels shown in Figure 2-10 provide two fuse panels, each with 20 3-70 ampere cartridge type fuse holders, comcode 406686980. These fuse blocks are UL recognized and provide a more compact design than previous fuse holders. The fuse block was developed by USD (Underwriters Switching Devices) to accommodate the WP-92461 series of fuses. These fuses offer a big advantage over other fuse types in that they are UL recognized to UL standard 198L “DC Industrial Fuses” and have a 170 Vdc, 100,000 ampere interrupt rating. Note: Each of the fuse panel groups (30A-30D) provides two fuse panels, one for the right side and one for the left side. ED83127-30 G-B (field installed) provides one GMT fuse module containing three fuse positions. Each fuse position may be equipped with a GMT fuse ranging from 1/2 to 5 amperes. The GMT fuse module offers the customer the option of using the distribution bay for small miscellaneous loads in the office that might otherwise require a separate fuse panel. ED83127-30 G-D (field installed) provides one 70-150A TPL type fuse block. These fuse blocks occupy two positions within the fuse panel.

2 - 20 Product Description Issue 5 May 2000 Alarm Circuit Module (BEP1) The alarm circuit module, apparatus code A-CP/BEP1, provides a means for indicating a power loss and a fuse or circuit breaker alarm for each fuse or circuit breaker panel. Indications of these alarms are by means of an LED and by contact closures. The BEP1 pack will accept nominal input voltages of 24 and 48 volts. Operation in ±130 volt distribution bay frames (not an option for circuit breaker distribution frames) is achieved by addition of a dropping resistor mounted on the fuse panel to drop the nominal 130 volt level to the nominal 48 volt level. The BEP1 alarm module is provided with the fuse or circuit breaker panels. These groups describe the nominal voltage at which the fuse (24, 48, or 130 volts) or circuit breaker panel will operate (24 or 48 volts). Figure 2-12 shows the layout of the alarm circuit module and Figure 2-13 shows the input (P102) and output (P101) connector pin descriptions. The alarm module provides two Form C contacts for power loss and three Form C contacts for fuse or circuit breaker failure. The alarm output connector references of audible, visual and remote given with each alarm module are arbitrary and are provided as a suggested standard for remote monitoring equipment. However, installation personnel may select any set of Form C contacts. When power loss to a panel occurs, a closure exists between pins 1 and 2 and pins 3 and 4 on the output connector (P101), while an open condition exists between pins 1 and 9 and pins 3 and 10. When a fuse or circuit breaker operates on a panel, a closure exists between pins 8 and 15, pins 11 and 12, and pins 13 and 14 of connector P101, while an open condition exists between pins 7 and 8, pins 6 and 12, and pins 5 and 13.

Issue 5 May 2000 Product Description 2 - 23 Alarm Circuit Module (BEP1), continued Detailed Circuit Description The BEP1 consists of two monitoring circuits, one for panel power loss and the other for fuse failures. These circuits are described as follows. Power Input: DC power (24, 48, or 130 Vdc through external resistor) is provided to P102 pins 11 or 6. Nominal input voltage to bridge CR101 is 24 Vdc. Bridge CR101 allows the BEP1 to operate from either positive or negative voltages. Output voltage of nominal 22 Vdc from CR101 is applied to relay K101 and LED DS101. Relay K101 is held normally operated and DS101 (green) is illuminated. Fuse or circuit breaker alarm power is provided through P102 pins 7 or 8. Bridge CR102 allows operation from either voltage polarity. CR102 output of 22 Vdc nominal is applied to relay K102 and LED DS102 (red). Fuse or circuit breaker alarm power is normally present only when a fuse or circuit breaker blows and thus K102 is normally released and DS102 is extinguished. The return path for the power monitor and fuse or circuit breaker alarm monitor is through P102-12 & 14. Power Loss Alarm: Loss of bus voltage will cause relay K101 to release and LED DS101 (green) to extinguish. Two Form C contacts on K101 are available through P101 to monitor for power loss. Fuse or Circuit Breaker Alarm: A cleared fuse or circuit breaker will apply power through P102 to operate relay K102 and illuminate LED DS102 (red). Three Form C contacts on K102 are provided through P101 for external alarms. Frame Alarm: In addition to the individual panel alarm indicators, there is a frame alarm lamp at the top of the bay. This frame alarm lights when power is lost to a fuse or circuit breaker panel or there is a fuse or circuit breaker alarm. Power for lighting the frame lamp is brought from the battery plant on an auxiliary battery supply (ABS) lead. Figure 2-14 shows the frame alarm and ABS termination points at the top of the cabinet. When ABS is from a positive ground battery plant, it is brought into the distribution bay on terminal E3. This signal is daisy chained through all the circuit modules. A fuse or circuit breaker failure or power loss on a circuit module sends the ABS signal back up to the frame lamp socket. The ABS return lead back to the battery plant is also connected to the frame alarm lamp via terminal E4 to complete the circuit.

2 - 24 Product Description Issue 5 May 2000 Alarm Circuit Module (BEP1), continued Detailed Circuit Description, continued In some installations, the use of a ABS lead from the battery plant may not be available or desirable. An alternative alarming method substitutes power from a load bus for ABS. A 22-gauge wire may be run from the battery bus of fuse or circuit breaker panel number 1 to terminal E3. The return lead from the frame lamp via terminal 4 would go to the discharge return bus located on the cable rack. The obvious consequence of this option is if power is lost to fuse or circuit breaker panel number 1, the frame alarm will not light.

Issue 5 May 2000 Product Description 2 - 25 Alarm Circuit Module (BEP1), continued Monitoring Multiple Alarm Modules for Negative Plants In most distribution bay applications, customers require remote monitoring of a frame, fuse or circuit breaker alarm only and not individual load buses. Therefore, fuse or circuit breaker alarms on multiple packs may be connected so that the remote fuse or circuit breaker alarm signal on one pack can be operated from the other packs. This daisy chain is factory wired so that frame fuse or circuit breaker alarm may be monitored from the position 1 alarm module. A fuse or circuit breaker alarm on any pack will cause current flow through opto-isolator U101 causing it to turn on and apply voltage to P102 pins 4 and 5. Pins 4 or 5 are alternately connected from pack to pack providing a common fuse or circuit breaker alarm output signal. The position 1 alarm module monitors the other packs by connecting its P102 pin 1 fuse or circuit breaker alarm input to P102 pin 4 of the position 2 alarm module. See Figure 2-15. Thus voltage from any pack with an active fuse or circuit breaker alarm will cause K102 of the position 1 pack to be operated via P102 pin 1, causing an alarm on its P101 contacts. This feature is intended to provide a local visual indication of a fuse or circuit breaker alarm (DS102 of the pack with the alarm) and remote monitoring of the Form C contacts of a single alarm module. All packs will alarm independently by simply disconnecting pin 1.

2 - 26 Product Description Issue 5 May 2000 Alarm Circuit Module (BEP1), continued Monitoring Multiple Alarm Modules for Negative Plants, continued Remote monitoring of power loss is furnished for individual fuse or circuit breaker panels. However, power loss alarms will probably not be remotely monitored in most applications because loss of power in a distribution bay usually results in a number of other simultaneous alarms from the battery plant and load equipment. If power loss alarm for the entire cabinet is desired, the installer must connect the alarm module output pins P101 - 1, 2, 3, 4, (close on alarm) or 1, 3, 9, 10 (open on alarm) as shown in Figure 2-16. The connections can be made with 26-gauge solid wire soldered or wire-wrapped to the 405095043 output connectors. These connectors are furnished with each alarm module.

Issue 5 May 2000 Product Description 2 - 27 Alarm Circuit Module (BEP1), continued Monitoring Multiple Alarm Modules for Positive Plants Opto-isolator U101 is current-direction sensitive. Therefore, remote monitoring of frame alarms for positive plants is wired differently than for negative plants. For positive plants, fuse alarms on multiple packs should be daisy-chained together via P101. This allows the remote fuse or circuit breaker alarm signal on any pack to be monitored from the position 1 alarm module. Three Form C contacts are provided. They must be connected to alarm module output pins on connector P101 - 5, 6, 7, 8, 11, 12, 13, 14, and 15 (see Figure 2-17). The connections can be made with 26-gauge solid wire and wire-tapped to the 405095043 output connector provided with each alarm module.
