3.7Electrical Grounding

WARNING: ELECTRICALLY GROUND THIS UNIT PRIOR TO START-UP. Failure to do so may result in serious injury or death!

Verify there is electrical continuity between the motor module and the junction box using a volt-ohm meter (Figure 2.1, Pump and Motor Labels). The junction box must be grounded to an earth ground following local electrical codes. Grounding lugs are provided within the junction box for this purpose. Check the continuity of your ground connection to the motor module using a volt-ohm meter.

The motor module flange may also be directly connected to an earth ground.

3.8Motor Protection - IMPORTANT!

Warranty on the flow-cooled motor is void unless proper quick-trip ambient compen- sated protection is used on all three motor lines. Subtrol may be used on pumps with Franklin Motors. Refer to the motor installation manual.
