1) Identify the specific location and position at which the unit is to be installed. Make sure to allow
sufficient clearance for conduit and/or cable connections. Mark the mounting surface where the top
edge and one side of the enclosure will be aligned.
2) The mounting points of the unit are located in a rectangular pattern 18.5” wide by 15” high. The
mount points are ¾” from the sides and 1½ ” from the top and bottom of the installed enclosure. The
standard unit comes with four 3/8”-16 bolts that are sized to work with threaded wall anchors or
channel nuts. Other mounting options, such as stands, are also available.
3) There are four rubber isolator assemblies in the mounting kit. Each isolator assembly is comprised of
two parts, a donut-shaped part and a T-shaped part. Insert a mounting bolt into the donut-shaped part
and insert it into the large holes on the front of the mounting flange on the back of the enclosure.
4) Install the T-shaped parts to the mounting holes on the rear of the enclosure and seat the donut
shaped parts onto the T-shaped parts. Note that the T-shaped parts fit very tightly in the mounting
hole.
5) Lift the unit into position and tighten bolts.
Wiring Requirements
We recommend using the supplied NEMA 4 (IP66) rated conduit connectors on the bottom panel of the
enclosure for routing power and signal lines, or other NEMA 4 (IP66) rated conduit connectors. The
standard configuration includes two 1-inch trade-size liquid tight conduit fittings. Other configurations,
including sealing fittings and bulkhead connectors, are available.
It is strongly recommended that installations include a flexible section of conduit; for example, three feet
of conduit or two feet of tubing to allow the shock and vibration isolators a full range of motion.
Connecting Power
Most units ship with conduit holes pre-punched. If the unit was ordered without pre-punched holes:
1) Drill a small pilot hole in the bottom panel for each conduit entry.
2) Use a Greenlee punch (or equivalent) to create a suitable hole.
3) Verify that the holes are free from burrs or sharp edges and all chips and metallic debris are removed
from the enclosure. All chips and metallic debris must be removed from the enclosure before
operation to prevent damage to the installed electronic equipment.
Warning! To avoid potential electric shock, follow National Electric Code safety
practices or your local code when wiring and connecting this unit to a power
source and to electrical sensors or peripheral devices. Failure to do so could result
in injury or death. Only qualified personnel should perform wiring procedures.
Warning! Before proceeding, make sure that incoming electrical power has
been disconnected and there is no electrical power on the leads you will be
connecting.
