Disconnect, lock out, and tag power at the panel before servicing the pump
When servicing equipment, use non-sparking tools and use caution when removing or
installing equipment to avoid generating a spark.

NOTE: The above readings do not include the added resistance of the power supply wires to the submersible pump. Therefore, for
the readings to fall within the above limits, the resistance should be checked at the submersible pump junction box. If the resis
-
tance readings are taken at the control box or magnetic starter, they will be sightly higher.
