Motor Cable Grounding Test
Do not connect the pump control cable
to the control box or incoming voltage
before verifying the pump ground;
otherwise, personnel will be exposed to
serious injury or death.
Using a volt-ohm meter, connect one lead to the
motor cable green/yellow ground lead. Connect
the other lead to an uninsulated point on the pump
body. The test circuit should close.
If the test circuit does not close, there is a defect in
the cable or motor which must be corrected.
Control Box Connections
This pump is shipped completely wired for the volt-
age shown on the nameplate, and is ready for op-
eration through an approved control box.
Ground and wire the control box in accordance
with the instructions accompanying it.
