Electrical Connections

Risk of severe injury or death by electrical shock.
• To reduce risk of electrical shock, disconnect power before working on or around the system. More
than one disconnect switch may be required to de-energize the equipment before servicing.
• If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected
application of power.
• Some pumps are supplied with lead wires and are intended to be hardwired using a junction box or
other approved enclosure. The pumps include a grounding connector. To reduce risk of electric
shock, be certain that it is properly connected to ground.
• In a 230 V direct wire installation, one side of the line going to the pump is always electrically ener-
gized, regardless of whether the liquid level control switch is open or closed. To avoid hazards when
installing or servicing, install a double-pole disconnect near the pump installation.
• Some pumps are supplied with a grounding conductor and grounding-type attachment plug. To
reduce risk of electric shock, be certain that it is connected only to a properly grounded grounding-
type receptacle. Do not remove the third prong from the plug. The third prong is to ground the pump
to help prevent possible electric shock hazard.
• Check electrical outlets with a circuit analyzer to ensure power, neutral, and ground wires are prop-
erly connected. If not, a qualified, licensed electrician should correct the problem.
• The flexible jacketed cord assembly mounted to the pump must not be modified in any way, with the
exception of shortening the cord to fit into a control panel. Any splice between the pump and the
control panel must be made within a junction box and comply with the National Electrical Code.

Wiring Guidelines

Check the pump label for proper voltage required. Do not connect to voltage other than that shown.
Be certain that this pump is connected to a circuit equipped with a ground fault circuit interrupter (GFCI)
device if required by code.
The pump should be connected or wired to its own circuit, with no other electric receptacles or equipment
in the circuit. The fuses or circuit breaker should be of ample capacity in the electrical circuit.

Line Voltage Connections

The VCMA pump has a power cord for connection to the power supply. The power cord must be connected
to a constant source of power matching the voltage specified on the pump nameplate. Do not connect to a
fan or any device that runs intermittently.
Models With Stripped Wire Ends
Some models are supplied with a stripped wire cord end. Power connections
must be made within a junction box, and must comply with the National
Electrical Code. Employ a licensed electrician.
The power cord wires are color coded as follows:
• Green/yellow - ground
• Brown - line, and
• Blue - line (230 V) or neutral (115 V)
