WARNING: Using a multi-meter, check the following voltages at the circuit breaker panel prior to connecting any equipment. Make sure proper polarity is followed and house ground is proven. (See Fig. 19.)

Check the power source:

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

Field-Connected Controllers

It is strongly recommended that all individually-pow- ered control modules and the heater should be supplied from the same power source.

NOTE: Field-supplied isolation relays should be installed when field- connecte d controllers are mounted more than 50 equivalent feet (18 AWG) from heater. See wiring diagrams.

NOTE: Minimum 18 AWG, 105°C, stranded wire must be used for all low voltage (less than 30 volts) external connections to the unit. Solid conductors should not be used because they can cause excessive tension on contact points. Install conduit as appropriate. All high voltage wires must be the same size (105°C, stranded wire) as the ones on the unit or larger.

Making the Electrical Connections

Refer to Fig. 18-21.

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

2.NOTE: Current draw noted on rating plate does not include pump current.

3.Turn off all power to the heater. Verify that power has been turned off by testing with a multi-meter prior to working with any electrical connections or components.

4.Observe proper wire colors while making electri- cal connections. Many electronic controls are polarity sensitive. Components damaged by im- proper electrical installation are not covered by warranty.

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

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

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