Power Supply and Wiring

Section 6
Power Supply
The controller requires a single-phase power supply of 230 volts +/- 15% on a dedicated 20-amp
DANGER
two-pole circuit breaker. A dedicated circuit means no other appliances use the same circuit! The
Hazardous
voltage
output power from the motor controller is three-phase, variable frequency and variable voltage.
Maximum output voltage and frequency are line input voltage and 60 Hz, respectively. Low supply voltage will
reduce pump performance.
Note
Installation and maintenance MUST be performed by properly trained and qualified personnel.
Always follow the National Electric Code or Canadian Electric Code, as well as all local, state and
provincial codes when wiring the system.
Wire and Conduit
Factory installed input and output power leads are supplied with the controller. Do not use wire smaller than 14
AWG. Use of Metal Conduit with Metal Conduit Connectors is recommended for all electrical connections.
Output Power Connections
Connect the motor leads for 230 volt, 200 volt, or 208 volt operation using the nameplate as a
DANGER
reference. Connect the output power leads from the controller to the 3 motor leads in the conduit
Hazardous
voltage
box on the motor. Connect the ground (green) output power lead to the ground screw in the conduit
box on the motor. This step is performed in its entirety at the factory for complete systems. See diagram 4 for
details
.
Note
If the pump has more than 50 feet of wire from the controller, consult factory for selection of an
output load filter (load reactor).
Connecting Input Power
Connect the 230 volt, single-phase power supply leads and Safety Ground wire from a 20 amp two-
DANGER
pole circuit breaker (in the OFF position) to one side of a 20-amp two-pole disconnect switch.
Hazardous
voltage
Connect the input power leads supplied with the controller to the other side of the disconnect
switch. Be sure to use Metal Conduit with Metal Conduit Connectors for electrical connections.
Danger
The controller has a high leakage current to ground. The terminals marked "GND" in the
DANGER
controller must be connected to the safety ground from the electrical service entrance.
Hazardous
voltage
Failure to properly ground the controller or motor will create an electrical shock hazard.
Note
Do not use GFCI protection with this controller. Nuisance tripping will result.
