Electrical Service And Operation - Liberty Pumps PROVORE 380 Serie Manuel D'installation

5. Electrical Service and Operation


Risk of electric shock. Always disconnect the pump from the power source before handling or making adjustments.

The electrical connections and wiring for a pump installation should only be made by qualified personnel.

This pump is supplied with a grounding conductor or a grounding-type attachment plug. To reduce the risk of electric shock, be
certain that the grounding conductor is connected only to a properly grounded control panel or, if equipped with a grounding-type
plug, that it is connected to a properly grounded, grounding-type receptacle.

Do not bypass grounding wires or remove ground prong from attachment plugs.

Do not remove cord and strain relief, and do not connect conduit to pump.

Do not use an extension cord.

This pump requires separate, properly fused and grounded branch circuit. Make sure the power source is properly sized for the
voltage and amperage requirements of the motor, as noted on the pump nameplate.

The electrical outlet or panel shall be within the length limitations of the pump power cord, and at least 4 feet above floor level to
minimize possible hazards from flood conditions.

The installation must be in accordance with the National Electric Code and all applicable local codes and ordinances.
All vertical discharge P380 models come factory-equipped with the float switch mounted on the QuickTree
models come with two cords - one to the float switch and the other to the pump motor. The switch cord has a series (piggyback) plug
enabling the pump (motor) cord to be plugged into the back of it (See Fig.4). The purpose of this design is to allow manual operation of
the pump. Note, on / off operation of the pump must be controlled by the circuit breaker.
For automatic operation the two cords should be interconnected and plugged into a separately fused, grounded outlet of proper amp
capacity for your selected pump model. (See Section 1, General Information, or the pump nameplate for electrical specifications of
your model.) Both cords are equipped with 3-prong plugs and must be plugged into a properly grounded 3-wire receptacle. DO NOT
REMOVE THE GROUND PRONGS.
In the event of switch failure, the pump cord can be separated
and plugged into the electrical outlet, directly bypassing the
switch. For 115V and 230V single phase pumps should only
be operated without the float switch by using the circuit
breaker or panel disconnect. Do not let the pump run dry.
If the pump is to be wired directly into a control device or
junction box, and it is necessary to remove the plugs, have a
certified electrician do the wiring in accordance with the
National Electric Code and applicable local codes.
In 230V installations, one side on the
line going to the pump is always "hot",
whether the float switch is on or off.
To avoid hazards, install a double
pole
