The cooling fin furthest on the right must drop over the edge rising up on
the fixing plate. Further slave inverters can be hung on the corresponding
mounting plates in the same way.
Remove the small protective plate on the right underneath the master
inverter before hanging the slave inverter. The protective plate on the first
slave must also be removed before hanging a second slave.
4.4 Connecting (AC) the master inverter
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.
First connect a separate group, making sure that this group is voltage-free.
Connect what will be the slave units first, then connect the solar modules
before turning on the power supply.
Unscrew the cover of the master inverter junction box.
The mains connection cable (AC output) is connected to the 3 WAGO
– spring clamp terminals via the cable feed fitted with a union nut. At
least 8 mm of insulation should be stripped from the end of the wire. If a
flexible connection cable is used a wire end sleeve should be crimped on.
The wire end should be inserted correct into the opened WAGO terminal
and then checked to make sure it is securely connected. The cable routeing
must be in accordance with the adjoining drawing.
The phase, neutral and earth cables must be connected to the correct
points ["Line-Neutral-PE" printed]. Tighten the union nut well (by hand).
This ensures that there is enough strain relief for the cable. If tools are used
incorrectly the union nut could become damaged.
