RECOMMENDED POWER AND CONTROL CONNECTIONS
DISCONNECT POWER AT THE FUSE BOX BEFORE
PROCEEDING.
OPERATOR MUST BE PROPERLY GROUNDED AND
CONNECTED IN ACCORDANCE WITH LOCAL ELEC-
TRICAL CODES. NOTE: THE OPERATOR SHOULD
BE ON A SEPARATE FUSED LINE OF ADEQUATE
CAPACITY.
ALL ELECTRICAL CONNECTIONS MUST BE MADE
BY A QUALIFIED INDIVIDUAL.
Before installing power wiring or control stations be sure to follow all specifications and warn-
ings described below. Failure to do so may result in severe injury to persons and/or damage to
operator.
For best protection against the environment follow directions below for recommended specifi-
cations for power and control wiring connections.
SUGGESTED CONDUIT & FITTINGS
Liquidtight Flexible Nonmetallic Conduit is permitted
for use in both exposed and concealed areas and for
electrical systems that require flexibility and protection
from vapors, liquids or solids.
LFNC conduit should be used for Liquidtight environ-
ments as stated by NEMA guidelines.
All conduit and conduit fittings should be marked as
“Liquidtight”, conduit and fittings marked “Raintight” or
“Wet Locations” are not to be automatically consid-
ered liquidtight.
NOTE: Select all conduit and conduit connectors
based on local code and application of job.
CONDUIT & FITTING PREPARATION
The most efficient assembly of a liquidtight conduit
and fitting system can be achieved, and optimum per-
formance ensured, by adherence to simple conduit
preparation and assembly techniques:
1. Square off ends of conduit by cutting the end of the
conduit squarely using a hacksaw or similar tool, con-
duit manufacturers sometimes offer cutting jigs for this
purpose.
2. Fully insert conduit flush with the fitting end stop.
3. Secure conduit to fitting. A compression gland nut,
when supplied as part of a fitting, will typically achieve
maximum securement.
4. Ensure conduit jacket is not cut or ripped in any
location along its surface.
NOTE: For conduit preparation, always follow the
conduit manufacturers instructions.
ATTACHMENT TO ENCLOSURE
1. Select proper fitting entry hole to be placed in
enclosure and punch through using drill or tool sup-
plied by manufacturer.
2. Slide threaded body into fitting hole in enclosure.
3. Insert gasketing around threaded area and secure
in place with nut supplied. (Refer to manufacturer
specifications for proper torque requirements).
NOTE: For fitting attachments, always follow the
manufacturers instructions.
ANY MAINTENANCE TO THE OPERATOR OR IN THE
AREA NEAR THE OPERATOR MUST NOT BE PER-
FORMED UNTIL DISCONNECTING THE ELECTRICAL
POWER VIA, THE MAIN DISCONNECT SWITCH.
UPON COMPLETION OF MAINTENANCE THE AREA
MUST BE CLEARED AND SECURED, AT THAT TIME
THE UNIT MAY BE RETURNED TO SERVICE.
