Control Wiring

Important points to remember about control wiring:

• Use Copper wire only. Wire gauge requirements and recommendations

are based on 75 °C (168 °F). Do not reduce wire gauge when using
higher temperature wire.

• Wire with an insulation rating of 600V or greater is recommended.

• Control wires outside the cabinet

should be separated from power wires

by at least 0.3 meters (1 foot).
