Wiring Instructions
Branch Circuit Connections (Power)
1. Wiring compartment access door is hinged. To open, turn single screw on the side until
the door swings away from the heater (See Figure 9). Do not try to remove screw.
2. A knockout is provided in the back of the unit for field wiring (See Figure 9). This is a
multiple diameter knockout. Use the diameter that fits the required conduit size.
3. A ground terminal is provided near the junction block for field wiring. The ground should
be connected before any other connections.
4. The junction block is equipped with box terminals sized to accept the correct power
supply wire. Wire rated at 600 volts and 75˚C is satisfactory for branch circuit
connections. Either copper or aluminum conductors may be used. NOTE: the center
box terminal on the three pole junction block is used only for 3-phase operation.
5. Each heater has a wiring diagram on the inside of the access door. Consult this
diagram before making any field connections.
