Safety and Conformity 2 8000038781_00_BAL_en / L00410564-01_02 1

fore installing the inverter. Installation: For optimum safety, follow the steps described in this manual. Keep in mind that the inverter has two voltage carrying sides; the PV input and the AC grid. Disconnecting the inverter: Before starting work on the inverter, switch off AC grid at the mains switch and PV using the PV load switch. Ensure that the device cannot be unintentionally recon- nected. Use a voltage tester to ensure that the unit is disconnected and voltage free. The inverter can still be charged with very high voltage at hazardous levels even when it is disconnected from grid/mains and solar modules. Wait at least 30 min. following disconnection from grid and PV panels before proceeding. Maintenance and modification: Only authorised personnel are allowed to repair or modify the inverter. To ensure optimum personal safety, only original spare parts available from the supplier should be used. If non-original spare parts are used, the compliance with CE guidelines in respect of electrical safety, EMC and machine safety is not guaran- teed. Also observe the danger of burn injury. The temperature of the cooling racks and components inside the inverter may exceed 70ºC. Functional safety parameters: Never change the parameters of the inverter without authorisation from the local energy supply company and instructions from AEG PS. Unauthorised changes of functional safety parameters may cause injury or acci- dents to people or inverter. Additionally it will lead to the cancellation of all inver- ter operating approval certificates. The AEG PS inverters are all designed according to the German VDE0126-1-1 (February 2006) standard, which includes an insulation test between PV array(s) and Earth, and a type B, RCMU according to DIN VDE 0100-712. 1.2. Hazards of PV Systems Very high DC voltages are present in the system even when the AC grid is disconnected. Faults or inappropriate use may lead to electric arcing. Do not work on the inverter while it has cur- rent connected to it. The short-circuit current of the photovoltaic panels is only slightly higher than the maximum op- erating current and depends on the level of solar irradiation. 1.3. PV Load Switch Illustration 1.1: Protect PV PV Load Switch The inverter has been equipped with a PV load switch (1) for safe disconnection of DC current. 1.

PV Connection Note: When choosing the installation place, ensure that all labels are visible at all times. For details refer to the section Specifications. Do NOT connect PV to earth! Use a suitable voltmeter that can measure up to 1000 V DC. 1. First verify the polarity and maximum voltage of the PV arrays by measuring the PV open circuit voltage.The PV open circuit voltage must not exceed 1000 V DC. 2. Measure the DC voltage between the plus-terminal of the PV array and Earth (or the green/yellow PE cable). The voltage measured should approximate zero. If the voltage is constant and not zero there is an insulation failure somewhere in the PV array. 3. Locate and fix the failure before continuing. 4. Repeat this procedure for all arrays. It is allowed to distribute the input power on the inputs unevenly, presuming that: • The nom. PV power of the inverter is not exceeded (10.3 / 12.9 / 15.5 kW). • The individual input is not exceedingly loaded, and not more than 6000 W. • The maximum short circuit current of the PV modules at STC (Standard Test Conditions) must not exceed 12 A per input. Illustration 3.13: DC Connection Area On the inverter turn the PV load switch into off position. Connect the PV cables by means of MC4 connectors. Ensure correct polarity! The PV load switch can now be switched on when required. 3. Installation 16 8000038781_00_BAL_en / L00410564-01_02 3

occur in the following situations: 1. The inverter runs in Master/Slave operation and only one or two PV in- puts are in use. In this case, the other inputs are not connected to PV and they are therefore open to intrusion. 2. Not all PV inputs are connected. 3. PV connectors are not fitted; for example in case of disconnection of parts of a PV plant over a longer period of time. In situations where the PV connectors are not fitted, a seal cap must be mounted (included in the scope of the delivery). All inverters with MC4 connections are de- livered with seal caps on inputs 2 and 3. During installation, the seal caps of those inputs that are to be used are discarded. Note: The inverter is protected against reversed polarity but it will not generate power until the po- larity is corrected. To achieve optimum production, the open circuit voltage (STC) of the PV modules must be lower than the max. input voltage of the inverter (see the specifications), multiplied with a factor of 1.13. UOC, STC x 1.13 ≤ UMAX, inv 3.7. Auxiliary Input/Output Note: When choosing the installation place, ensure that all labels are visible at all times. For details refer to the section Specifications. The inverter has the following auxiliary input/output: • 2 x RJ45 for RS485 • 2 x RJ45 for Ethernet • 1 x 8 pole terminal block for RS485 • 1 x 10 pole terminal block for - PT1000 temperature sensor input x 3 - Irradiation sensor input - Energy meter (S0) input • 1 x 2 pole terminal block for relay outputs Refer to the specifications for an overview of the communication board and to the inverter user manual for details regarding auxiliary input configuration via the display. 3.8.

network is limited to 50. 2) For outdoor use, we recommend outdoor burial type cable (if buried in the ground) for both Ethernet and RS485. 3) Third input is used for compensation of the irradiation sensor. 4) The number of inverters to be connected in the RS485 network depend on which peripheral device is connected. To ensure fulfilment of IP enclosure rating, correctly mounted cable glands are es- sential for all peripheral cables. To ensure EMC compliance, shielded cables must be applied for Sensor inputs and RS485 communication. Unshielded cables may be applied for alarm outputs. Other auxiliary cables must pass through the designated EMC cable clamps to es- tablish mechanical fixing and in case of shielded cable termination to the shielding device.

Note: The two network types cannot be mixed. The inverters can only be connected in networks which are either solely RS485 or solely Ethernet. Note: Each inverter has a unique RS485 address when it is delivered. This address is defined at the time of production. Note: Ethernet connection is recommended for faster communication. RS485 connection is required when a web logger or data logger is connected to the inverter. 5. Technical Data 8000038781_00_BAL_en / L00410564-01_02 31 5
