2.3. Wiring

Before beginning controller wiring, be sure power has been removed, locked out and tagged as under

repair, before proceeding. Observe all national and local electrical codes during wiring and installation

to best assure your safety and the safety of the pool operations staff and swimmers.

Wiring Guidelines

1.6. AC Controller Power

Power the controller using a dedicated, separate breaker in the local lighting-distribution panel.

Do not route the controller AC power in common conduit with variable frequency pump drives.

1.7. AC Power to Solenoid Pumps, Valves & Solenoids

Controller ON/OFF relays switch and power the AC line to valves, solenoids and solenoid pumps. Ensure

that each valve & solenoid has a dedicated neutral cable between the controller and the valve or

solenoid. Do not share a common neutral to multiple valves or solenoids.

1.8. Fractional Horsepower Chemical Feed Pumps

The controller ON/OFF relays 1 through 3 are fused at 5 amps total which will power multiple solenoid

driven chemical feed pumps and solenoid coils, but not the larger fractional horsepower rotational motor

pumps. Fractional horsepower feed pumps (>1/8 HP) are commonly used in high pressure chemical

feed applications and for large volume Sodium Hypochlorite pumps.

Typically, the high motor inrush current requires a dedicated breaker and separate AC feed from the

controller AC power breaker.

1.10. Sensor Wiring

Analog sensors (pH, ORP, and Temperature), contact sets, water meters and flow switches may be

cabled in a common conduit without causing operational problems.

Do not mix AC Line, 120VAC wiring with any sensor or communications cable in a common conduit.

Grounded, metallic conduit is preferred in areas where variable frequency drives operate.

CAUTION

Fractional horsepower chemical feed pumps cannot be directly powered by the

controller. Use the controller 120VAC control output to switch a motor start relay with a

120VAC coil for these type pumps or feeders.
