Wiring the HTC (Electric Process
Heater) to the HTC Controller
IMPORTANT:
Always refer to the proper wiring diagram supplied with your
equipment before making electrical connections.
CAUTION: Always disconnect and lock out the main power sources before
making electrical connections. Electrical connections should be made only by
qualified personnel.
1
Refer to the wiring diagram that came with your control.
2
Insert the control wires through a knockout in the side or bottom of the HTC
control center.
Secure with a appropriately-sized strain relief, if conduit is not
used.
3
Connect the high temperature and pressure switch wires to the control
center's terminal block.
4
Insert the other end of the control wires through the knockout in one side of
the HTC heater assembly terminal box.
Secure with a appropriately-sized strain
relief, if conduit is not used.
5
Connect the high temperature and pressure switch wires to the heater
assembly terminal block.
IMPORTANT: The connection between the heater and control center should
be made with customer supplied wire that has properly sized conductors
and properly protected with customer-supplied conduit. The routing should
be neat and away from potential mechanical damage. The terminations
should be landed on the terminals in the control center and heater junction
area. These terminations should be regularly checked to prevent loosening
and shorting to ground.
