Cable lugs for M10 bolts according to SN71322 are suitable for cables with cross-sections of
35 mm
2
… 185 mm
2
(1 AWG … 2 × 350 MCM).
If you wish to establish connections with cables of 240 mm
2
(500 MCM), you must use
narrow cable lugs, e.g. Klauke 12SG10. Other cable lugs are not suitable due to the narrow
design of the converter.
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.
WARNING
Damage to converter 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.
