MOUNTING
actly the same mounting dimensions. Mount by
either of two methods: (a) use two #10 screws
from the front, or (b) use two #10-32 UNF screws
from the back. HDLS offers the advantage of
front mount construction. The electrician will find
a complete switch, with no parts missing and
ample wiring space.
W ith plug-in construction, wiring and conduit
connection is made to the base receptacle. This
feature also reduces downtime, since plug-in unit
can be removed without disconnecting wiring or
conduit.
