Additional information when connecting FSG inverters
Note
Conductor cross-section 240 mm
Cable lugs for M10 bolts according to SN71322 are suitable for cables with cross-sections of
35 mm
If you wish to establish connections with cables of 240 mm
cable lugs, e.g. Klauke 12SG10. Other cable lugs are not suitable due to the narrow design of
the inverter.
The maximum permissible width of the cable lugs is 37 mm (1.45 inches).
Remove the plastic insulating plate as shown below to gain better access to the terminals for
the power connections.
Damage to inverter as a result of operation without insulating plates
Without the insulating plates, voltage flashovers may occur between the phases.
● Replace the insulating plates after connecting the cables.
