Knockouts
Safety
General
The wall bracket contains several knockouts of different sizes. When knocked out, the
openings are used for the inputs of various wires.
1/2 in. for data communication cable (DATCOM)
3/4 in. - 1 1/4 in. for AC and DC cables
* A grounding electrode terminal (GET) may be required depending on local regula-
tions.
The cable for the grounding electrode terminal can be fed through the designated
opening on the underside of the wall bracket.
IMPORTANT! The knockouts on the rear of the wall bracket are made of metal.
NOTE! When using the cable inlets at the back, take care to seal them according
to protection class NEMA4X before operating outdoors.
NOTE! When installing outdoors, only use waterproof conduit fittings and con-
duits. Conduit fittings and conduits are not part of the scope of supply for the in-
verter.
CAUTION! Danger of short circuit from loose metal parts from knockouts. Loose
metal parts in the inverter may cause short circuits when the inverter is powered
up. When removing knockouts, make sure that
- no loose metal parts fall into the connection area of the inverter,
- any metal pieces that do fall into the connection area are removed immedi-
ately.
