Electrical Power Connections, Surge Protection

Electrical Power Connections

Installations must follow these codes:

·National Electrical Code and any other national, state, provincial or local codes or regulations hav- ing jurisdiction

·Safety wiring must be N.E.C. Class 1

·Heater must be electrically grounded as required by N.E.C.

·In Canada, C22.1

The heater is wired for 120 VAC, 12 AMPS. The volt- age is indicated on the tie-in leads. Consult the wiring diagram shipped with the heater in the instruction packet. The remote tank control stat, thermostat, or electronic heater control as applicable, may be con- nected to stage selector terminal (See wiring diagram). 24 Volts are supplied to this connection through the heater transformer. DO NOT attach line voltage to the “TH” leads. Before starting the heater check to ensure proper voltage to the heater and pump.

Install a separate disconnect means for each load. Use appropriate-sized wire as defined by NEC, CSA and/or local code. All primary wiring should be 125% of minimum rating.

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

Surge Protection

Microprocessor-based and solid state controls are vul- nerable to damage from voltage and amperage fluctuations in the power supply. All sensitive control components should be protected by a suitable com- mercial-grade surge protection device.

If any of the original wire as supplied with the heater must be replaced, it must be replaced with 105°C wire or its equivalent.

Check the Power Source

WARNING: Using a volt-ohm meter (VOM), check the following voltages at the terminal block inside the unit. Make sure proper polarity is followed and house ground is proven.

AC = 108 Volts AC Minimum, 132 Volts AC MAX AB = 108 Volts AC Minimum, 132 Volts AC MAX BC = < 1 Volt AC

Making the Electrical Connections

Refer to Fig. 14 Wiring Connection, and the Wiring Diagram.

1.Verify 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 volt-ohm meter prior to working with any electrical connec- tions or components.

3.Observe proper wire colors while making electrical connections. Many electronic controls are polarity sensitive. Components damaged by improper electrical installation are not covered by warranty.

4.Provide an external surge suppressor capable of maintaining system integrity.

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 manufacturer’s instructions.

7.Conduit should not be used as the ground. There must be a solidly wired ground.

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