pump must be approved by the Gor­
man‐Rupp Company for the application.
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.
Liquid Level Devices
The pump may be controlled to perform filling and
dewatering as shown in Figure B‐3 by using the
float switch and liquid level control offered as op­
tions.
Overheating will occur if the liquid level falls
below the level required to cool the pump
motor (see LIQUID LEVEL in Operation,
Section C).
