Telguard TG-KIT LTE Manuals

56050701 INSTRUCTIONS for TG-KIT LTE Conversion of TG-7 Series to Telguard TG-7 LTE The TelguardTG-KIT LTE can be used to convert an older TG-7 series device (2G, 3G/4G, or CDMA) to a comparable TG-7 LTE model. Pre-Installation checklist:  Four (4) standoffs.  Four (4) mounting screws.  One (1) washer.  One (1) metal plate  NEW TG-7 LTE circuit board  Terminal Blocks  Labels Conversion Procedure: Note: Prior to beginning the hardware conversion, identify the type of enclosure you are dealing with. If the P/N of the original unit ends in 001, you have a “Legacy” unit. A. Disconnect all power to the Telguard unit. This includes both AC power transformer and battery. If the unit is a Legacy device, then a metal plate (included) is needed to convert the dual board chassis to a single board chassis. B. Remove the TG7 circuit card(s) from chassis by doing the following steps: 1. Disconnect the wires from terminal block. 2. Disconnect the antenna (or antenna cable if dealing with a TG-7A). 3. Remove the antenna TNC connector’s retaining nut and washer. Set these aside for later use. (Figure 1) If the unit is a Legacy 2G device, the daughter cards are secured with small brackets. Unscrew these brackets to remove these cards. 4. Remove all the screws securing the current circuit board. If the unit is a Legacy 2G device, you will have four mounting screws and a green grounding screw (Figure 2). For other models there are only three mounting screws in addition to the grounding screw. 5. Set aside these mounting screws for future use and remove old circuit board. For Legacy 2G devices, you may need to first remove the Modem card. If so, set Modem Card and bracket screws aside for later use. (Figure 2) 6. If you have a Legacy 2G TG-7A you must remove the antenna bracket. (Figure 3) Figure 1. Figure 2. Figure 3. Bracket Screws Antenna retaining nut Modem Card Mounting Screws Antenna Bracket
