installed according to the unit’s power supply requirements
and local electrical codes.
B. NEMA 12 MODELS
1. Nema 12 units are designated by the letter “J” in the model
number suffix. These units are constructed with a dust tight
electrical enclosure and branch circuit fusing. Electrical
power supply requirements are identified on the equipment
data tag. Verify that available voltage supply is the same as
the unit’s voltage requirements.
WARNING: DO NOT CONNECT THE UNIT TO A
VOLTAGE SUPPLY SOURCE NOT EQUAL TO THE
UNIT’S VOLTAGE REQUIREMENTS AS SPECIFIED ON
THE UNIT’S DATA PLATE.
Use of incorrect voltage will void the unit’s warranty and
cause a significant hazard that may result in damage to the
unit or serious personal injury.
2. Appropriate conduit and fittings should be selected which
will maintain the integrity of the cabinet.
3. Supply a power conductor sized according to the unit’s
power supply requirements. Connect the power conductor
to the unit’s power supply
entry terminal block.
C. CONTROL CIRCUIT WIRING
1. The unit’s supplied control
circuit is 110 volt, 1 phase,
60 cycle. The control circuit
is supplied by the factory
installed transformer.
A control circuit fuse is
provided (figure 2.5C).
D. GENERAL
1. Make certain all ground connections to the unit are properly
affixed. A proper connection to earth ground is required. A
conduit ground is not a reliable conductor!
2. Make certain the power conductor, disconnecting means,
and fusing are properly sized according to the unit’s power
supply requirements.
3. Make certain all electrical connections are tightly affixed.
Any loose wiring connections must be tighten before
engaging the power supply.
