Connecting op-
tion cards, laying
data communica-
tion wires
3 = one wire input for both data communication wires
4 = separated wire inputs on opposite sides (e.g., when several inverters are installed
next to each other)
CAUTION! Danger of short circuit by 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 inverter
- any metal pieces that do fall into the inverter are removed immediately
NOTE! The knockout for the data communication wires must be above the plastic
dividers so that the plastic dividers are always under the data communication
wires.
NOTE! Use only water tight conduit fittings and conduits. Conduit fittings and con-
duits are not part of the scope of supply for the inverter.
NOTE! Before connecting data communication wires to an option card, lead the
wires through the ferrite delivered with the inverter and build a loop.
