INSTALLATION: ELECTRICAL WIRING
WARNING
Hazardous voltage can shock, burn, or
cause death.
CAUTION
Improper wiring can result in permanent
damage to the system. Pump connection must comply with National
Electric Code (NEC) or Canadian Electric Code (CEC)
and all applicable local codes.
WARNING
If you are not sure of the proper electrical
connections, employ a competent electrician for the installation. This
ensures the installation complies with all noted electrical codes.
Disconnect power at electrical panel before making any electrical
connections. Supply voltage must be +/- 10% of device nameplate
voltage.
Low or high voltage can damage the device and will void the
warranty. Connect device to dedicated branch circuit with no other
appliances on it.
A fused disconnect switch or circuit breaker should be placed at
or near the pump as required by local electrical codes.
NOTICE
Before installing the device, carefully check
the technical features and make sure they comply with those of the
pump and the system. The control label displays maximum pump hp.
Confirm compatibility between this device and the chosen pump.
NOTICE
Follow all indications on the electrical diagrams
shown in Figure 7.
WARNING
Serious or fatal electrical shock may
result from failure to connect the pump and control to the service
entrance ground. Also ground metal plumbing and all other metal
near the device. When grounding these components, use a wire no
smaller than the power supply wires from the circuit breaker to the
device. To reduce the risk of electric shock, disconnect power before
working on or around the water system.

Installation Procedure: Wiring
1.
Disconnect electrical power at the main breaker.
2. Confirm the voltage rating matches the pump/motor's voltage
rating and that the device's hp/kW rating is equal to or greater
than that of the pump/motor.
3. Verify that the dedicated branch circuit for the device is
equipped with a proper listed fuse/listed circuit breaker.
4. Remove the cover of the device by removing the screws as
shown in Figure 4. Cover features and label may vary based
on your model.

5. If mounting in wet environments, liquid-tight cables (Figure 5)
or flexible conduit fitting (Figure 6) are required (not supplied)
to ensure that the enclosure maintains a watertight Type 4
rating. Install the liquid-tight cables or flexible conduit fitting
into the conduit nuts in front of the power supply and motor
connectors (Figures 5 and 6).
WARNING
conduit and fittings must be used to maintain Type 4 rating
(Figures 5 and 6). If you use water-resistant cables to run
electrical wire to the pump (Figure 5), tighten the supplied
cable/conduit connector to torque of 106 in-lbs (13 Nm).
If you use flexible conduit fittings to run electrical wire to the
pump (Figure 6), tighten the supplied cable/conduit connector to
a torque of 106 in-lbs (13 Nm), compressing the O-ring against
the outside housing of the flow control.
