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 configurations 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.
