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.
Then remove the screws from the cover of the master inverter's junction
box and open the flap.
Now you can guide the AC cable and the data cable to the control unit.
The cable loop remains in the bracket in order to shorten the cable for the
left-hand slave inverter to a suitable length.
The loop must be removed for connecting the right slave. The cable cover
does not need to be removed in order to feed the cable.
Fix the internal 30 V AC cable(s) from out of the inverter to the con-
nectors in the control unit (input or 3). Repeat this procedure with the
communication cables. Fix these cables from the inverter to the plug con-
nectors in the control unit. When doing so, ensure that the communication
cable is connected to the correct position number relating to the corre-
sponding 30 V cable.
Close the cover again.
