Check the power source:

AC = 108 VAC Minimum, 132 VAC MAX AB = 108 VAC Minimum, 132 VAC MAX BC = <1 VAC Maximum

prior to working with any electrical connections or components.

3.Observe proper wire colors while making electri- cal connections. Many electronic controls are po- larity sensitive. Components damaged by improp- er electrical installation are not covered by warran- ty.

4.Provide overload protection and a disconnect means for equipment serviceability as required by local and state code.

5.Install heater controls, thermostats, or building management systems in accordance with the applicable manufacturers’ instructions.

6.Conduit should not be used as the earth ground.

NOTE: A grounding electrode conductor shall be used to connect the equipment grounding conduc- tors, the equipment enclosures, and the grounded service conductor to the grounding electrode.

Field Wiring Connection

Fig. 19: Multi-meter

If the heater does not have a factory-wired stage con- troller, it is factory-wired in an on-off configuration with other stage terminals jumpered.

To field-connect a stage controller, remove factory- installed jumper and wire stage controller as shown in Fig. 21.

Making the Electrical Connections

Refer to Fig. 18-23.

1.Verify that circuit breaker is properly sized by referring to heater rating plate. A dedicated circuit breaker should be provided.

2.Turn off all power to the heater. Verify that power has been turned off by testing with a multi-meter
