Thermolator TW Series UGH025-0504
Before beginning, note the electrical specifications on the
nameplate mounted to the side of the unit.
The electrical
hookup must match these specifications with +/- 10% maxi-
mum voltage variance. An improper power supply could dam-
age the unit as well as seriously injure an operator.
The electrical hookup also should run through a fused discon-
nect sized for the nameplate amperage and conforming to
Article 250 of the National Electrical Code.
Open the unit’s electrical enclosure.
Insert the main power wire through the
knockout hole in the right side of the enclosure.
Secure the power wire with a rubber
compression fitting or strain relief.
Connect the power wires to the terminals.
Connect the three hot
wires to L1, L2, and L3
on the terminal block.
Connect the ground
wire to the copper
grounding mount. If you
have installed a discon-
nect device, follow the
manufacturer’s wiring instructions.

NSTALLATION
WARNING: Electrical shock hazard
This equipment is powered by three-phase main
voltage. Always disconnect and lock out the main
power source before performing any work
involving electrical connections. All wiring,
disconnects and fusing should conform to your
region’s electrical codes and should be installed
only by qualified personnel.
IMPORTANT: Always refer
to the wiring diagrams that
came with your temperature
control unit before making
electrical connections. The
diagrams show the most
accurate electrical compo-
nent 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 stated on the name-
plate mounted on the side of the unit.
r
Verify that resistance to ground on
each phase is at least 1 meg ohm.
