PUMP MODULE POWER SUPPLY
After all water and plumbing connections have been completed, a licensed, qualified electrician should connect the
power supply to the pump. It is important to follow the National Electrical Code (NEC), as well as any local codes to
ensure a safe installation.
4.1
ELECTRICAL SPECIFICATION
Establish that the circuit to be used to power the pump module is of the same electrical specification as the pump
module. The BIGHORN electrical specification can be found on the serial number data plate on the pump module
(inside the pump control box).
4.2
ELECTRICAL CIRCUIT
The circuit to the pump module must be dedicated and properly sized to carry the electrical load placed upon it by
the pump motor. Please refer to the serial number data plate on the pump module for more details.
4.3
ELECTRICAL POWER SUPPLY
The power supply to the pump module must be hard wired to a correctly rated fuse protected circuit complying with
NEC guidelines. NOTE : This pump unit has a frequency inverter. If local electrical code requires a GFCI (Ground
Fault Circuit Interrupted), this pump will require a special GFCI unit. Please contact MicroCool for details.
4.4
TERMINAL STRIP - POWER
After verifying all of the above, power should be on to the terminal strip located inside the NEMA 3R electrical
enclosure mounted on the pump module. We recommended that the correct sized wiring be in conduit (preferably
liquid tight); make the final connection to the high voltage terminal strip.
4.5
ELECTRICAL CONNECTIONS- LOW VOLTAGE
NOTE: All control wiring such as remote start must be SHIELDED cable of suitable size, for this application.
