IMPORTANT: Always refer to the
wiring diagrams that came with
your temperature control unit before
making electrical connections. The
diagrams show the minimum size
main power cable required for your
unit, and the most accurate electrical
component information.
IMPORTANT: Before initiating power
to the unit:
r Check the system for leaks.
r Verify that the voltage, phase,
frequency, amperage, disconnect
fuse, and minimum wire size
meet the specifications.
r Verify that resistance to ground
on each phase is at least 1 mega
ohm (use a multi-meter, not a
megger for this measurement).

Before beginning, note the electrical specifications on the serial tag mounted to the side of
the unit. The electrical connection must match these specifications with +/- 10% maxi-
mum voltage variance. An improper power supply could damage the unit as well as seri-
ously injure an operator. The electrical connection should run through a fused disconnect
sized for the amperage noted on the serial tag and conforming to all local and national
codes, including Article 250 of the National Electric Code.

This equipment should only be installed, adjusted, and serviced by qualified tech-
nical personnel who are familiar with the construction, operation, and potential
hazards of this type of machine.
All wiring, disconnects, and fuses should be installed by qualified electrical
technicians in accordance with electrical codes in your region. Always maintain
a safe ground. Do not operate the equipment at power levels other than what is
specified on the machine serial tag and data plate.
1
Open the unit's electrical enclosure. Removing
the top panel is recommended. The Thermolator
comes from the factory with a knockout for
1/2 inch conduit. A knockout punch should be
used if necessary to enlarge the hole for larger
diameter conduits.
2
Insert the main power wires through the conduit in the right side of the
enclosure. See electrical prints for recommended wire size.

NOTE: If using a flexible cord, secure the wire with a rubber
compression fitting or strain relief.
3
Connect the power wires to the terminals
indicated on the wiring diagram that came with
your machine. The Thermolator comes pre-wired
expecting clockwise (L1-L2-L3) phase rotation.
4
Check every terminal screw to make sure wires are
secure. Gently tug each wire. If a wire is loose, use a
screwdriver or allen wrench to tighten the terminal.
5
Connect the ground wire to the grounding lug shown in the
wiring diagram shipped with your unit.
