Installation Instructions for the
HDLS Series Switches
WARNING
PERSONAL INJURY
DO NOT USE these products as safety or emergency
stop devices or in any other application where failure
of the product could result in personal injury.
Failure to comply with these instructions could
result in death or serious injury.
MOUNTING
All Heavy Duty Limit Switches (HDLS) have exactly 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.
With 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.
To mount either switch, merely tighten mounting screws,
tighten plug-in unit or cover screws, and make sure
conduit section is sealed. Use of sealant (teflon tape,
pipe dope, etc.) is recommended to seal conduit
connection.
Because of moisture condensation problems, it is not
good practice to mount the switch upside down or at the
low point of conduit runs.

WIRING
Use size #12AWG or smaller solid or
stranded wire to connect to the
pressure type connector terminals.
Spades may be up to .312" wide,
rings up to .312" dia. With spade or
ring type connections, preinsulated
connectors or heat-shrinkable tubing
should be used to provide insulation
between terminals. Circuit diagram is
shown on the nameplate.
It will be easier to wire the double-
pole units by connecting lead wires to
the terminals nearest the conduit opening first. A
grounding screw is located in the housing near the
conduit opening.
Switch units with an indicator light in the cover are
furnished with the lead wires from the light connected to
the normally-open male terminals (#3 and #4) unless
otherwise specified on the order. Wires can be
unsoldered and reconnected to the normally-closed male
terminals or they can be ordered connected to the
normally-closed terminals by using a modification code
(refer to Catalog 40). Always connect these wires to the
same set of terminals used for the load. Across the
normally open male terminals (#3 and #4) the light will
be On (Fig. 1). Across the normally closed terminals (#1
and #2) the light will be Off.
