Connecting the inverter to the mains
DANGER!
Fatal electric shock hazard!
■
■
Make sure the AC input conductor is not live during connection work.
Connection conditions
■
■
Comply with the connection conditions set by the grid operator.
■
■
M40 cable gland; suitable for cable
Ø
: 24 to 33 mm
■
■
Connection type: screw terminals (UWV 25)
■
■
Permissible conductor cross sections:
– flexible conductor (with or without conductor sleeve): max. 25 mm
2
– rigid conductors: max. 35 mm

■
■
The protective conductor of the AC input conductor should be cut at least 30 mm
longer than the other conductors.
■
■
The AC input conductor must be fused. Minimum conductor cross sections and sug-
gested mains fuses:

■
Make sure the ambient temperatures for the mains fuses specified by the producer
are not exceeded.
WARNING!
Fatal fire risk!
■
■
Provide separate fuses for each inverter.
■
■
Do not connect any loads between the inverter and the mains fuse.
■
■
If you use external residual current devices (RCDs), use the type B RCDs with a nom-
inal fault current of 100 mA. For PV plants with large stray current capacities, the
RCDs to be used should have a nominal fault current capacity of 300 mA.
Procedure
1. Remove the cover of the inverter as described in section 5.1.
2. Thread the AC input conductor through the cable gland.
