Mounting on base plate without DIN rail adapter
All size S00 to S2 direct-on-line starters and size S00 reversing starters may be mounted directly
on the base plate.
The load feeder is screwed to the base plate. The device enclosures contain fastening holes, as
well as openings for screw-mounted push-in lugs.
CAUTION
Short-circuit hazard
In con󹪝gurations with a limiter, insulation of the base plate is necessary to avoid a short-circuit
to the base plate in the event of a short-circuit of the motor starter protector. If the limiter and
the feeder are mounted on the DIN rail adapter, insulation is not required.
