Electrical Connections continued
• Use circuit breakers on the incoming power lines.
• Grounding must be in accordance with NEC and CEC. If multiple AQUAVAR controllers are
installed near each other, each must be connected to ground. Take care to not form a ground
loop. Maintain a common ground.
• Wire must be made of copper and rated 60 / 75ºC (unless otherwise specified in the table
below). Refer to Tables 4, 5 and 6 for recommended wire gauges and temperature ratings.
Considerations for Control Wiring
Control wiring refers to the wires connected to the control terminal strip. Select control wiring
as follows:
• Shielded wire is recommended to prevent electrical noise interference from causing improper
operation or nuisance tripping.
• Use only UL™ recognized wire.
• Wire voltage rating must be at least 300 V for 230 Vac systems.
