EN 4.5 Connecting (AC) the slave inverter(s) WARNING Risk of death by electrocution! � � � When working on the solar system, disconnect the inverter from the power supply. Make sure that the power supply cannot be unintentionally switched on. Connect the slave units first, then connect the solar modules before turning on the power supply. When the slave inverters are installed at the same time as the master inverter the AC side is still voltage-free. If the slave units are not installed at the same time as the master inverter but later, disconnect the AC voltage first. 1 2 3 4 5 � � � � � Then remove the screws from the cover of the master inverter's junction box and open the flap. Now unscrew the protective cap on the underside of both the master and slave inverter and remove the small protective plate on the right underneath the master inverter. If you wish to connect a second slave inverter remove the small protective plate on the left-hand slave as well. � 7 6.439 | 10.04 Now both the AC cable as well as the data cable of the slave inverter can be seen. Now you can guide the AC cable and the data cable to the junction box. To shorten the cable for the left-hand slave inverter to a suitable length, wind it once round the back of the capstan. The length of the cable for the slave inverter furthest on the right has been calculated so that it can be connected just right. Fix the internal 30 V AC cable(s) from out of the inverter to the connectors in the control unit (input or 3). Repeat this procedure with the communication cables. Fix these cables from the inverter to the plug connectors in the control unit. When doing so, ensure that the communication cable is connected to the correct position number relating to the corresponding 30 V cable. Close the cover again. 37
