SECTION 4:
INSTALLATION AND WIRING
4.1 GENERAL
Enclosed IQ devices are factory wired and tested.
Installation requires solidly mounting the enclosed unit
and connecting field wiring. ALL FIELD WIRING
SHOULD BE #14 AWG MINIMUM. Included in this
booklet are diagrams of the factory wiring and various
field wiring options. Review and understand the
appropriate diagrams for the catalog number of the unit
you have ordered.
4.2 MOUNTING LOCATION
Choose a location that offers a flat, rigid mounting
surface capable of supporting the weight of the
equipment. Units without an uninterruptable power
supply will weigh 82 lbs (47 kg) maximum. Units
equipped with an uninterruptable power supply will
weigh 102 lbs (37.5 kg) maximum. Mount the equipment
in a suitable environment. These enclosures are
designed for either NEMA 3R or NEMA 12
environments. The catalog number identifies the
enclosure. If there are any doubts as to location
suitability, discuss them with your Cutler-Hammer
representative. Check to make certain that there are no
pipes, wires, or other mounting hazards in the immediate
mounting area that could create a problem. Carefully
remove all packing material from the unit. Even though
an equipment inspection was made when the equipment
was received, make another careful inspection of the
enclosure and the devices inside as packing material is
removed. Be especially alert for distorted metal, loose
wires, or damaged components.
4.3 MOUNTING PROCEDURE
The enclosures are provided with four elongated
mounting holes, two at the top mounting flange and two
at the bottom.
CAUTION
EXTREME CARE SHOULD BE TAKEN TO PROTECT
THE EQUIPMENT FROM DRILL CHIPS, FILINGS,
AND OTHER CONTAMINANTS WHEN MAKING THE
WIRE ENTRY HOLES AND MOUNTING THE
ENCLOSURE TO PREVENT COMPONENT DAMAGE
OR A FUTURE MALFUNCTION.
IF YOUR EQUIPMENT WAS ORDERED WITH THE
UNINTERRUPTABLE POWER SUPPLY OPTION, IT
WAS SHIPPED SEPARATELY. IT MUST REMAIN IN
AN UPRIGHT ORIENTATION. PLACE THE UPS ON
ITS MOUNTING BRACKET AFTER THE ENCLOSURE
HAS BEEN INSTALLED.
STEP 1: Install required mounting bolt anchors and the
two upper mounting bolts in the mounting
surface.
STEP 2: Gently lift the enclosure and guide the elon-
gated holes in the upper mounting flange over
the upper mounting bolts, but do not com-
pletely tighten the bolts.
STEP 3: While still supporting the enclosure, install the
two lower mounting bolts in the lower mounting
flange, but do not completely tighten. Use
shims, if required, to prevent deformation of the
enclosure when tighting the bolts, if the mount-
ing surface is distorted.
STEP 4: Tighten all four mounting bolts after any
required shimming is completed.
4.4 WIRING
WARNING
CONTROL WIRING MAY HAVE VOLTAGE PRESENT
THAT CAN CAUSE SEVERE PERSONAL INJURY OR
DEATH. DE-ENERGIZE ALL CONDUCTORS BEFORE
BEGINNING TO PERFORM ANY WIRING ACTIVITY
TO OR WITHIN THE ENCLOSED IQ DEVICE.
THE DISCONNECT SWITCHES IN THIS UNIT
DISCONNECT CONTROL OR SENSING VOLTAGE TO
THE IQ METER. WHEN THESE DISCONNECTS ARE
IN THE 'OFF' POSITION, THE CURRENT
TRANSFORMER CIRCUIT, FUSES, WIRING,
RECEPTACLE, ARII AND INPUT/OUTPUTS ARE
ENERGIZED. A DISCONNECTING MEANS AND
UPSTREAM PROTECTION SHOULD BE INSTALLED
FOR ALL CIRCUITS. A SHORT CIRCUIT TYPE
TERMINAL BLOCK IS PROVIDED FOR THE
CURRENT TRANSFORMER CIRCUIT.
A DEVICE EQUIPPED WITH A SEPARATE SOURCE
POWER SUPPLY MODULE CAN BE WIRED FOR 96-
