3.5 Checks to Make Before Installation
• When a grounded plug is used:
Use the megohmmeter to measure the insulation resistance between
the cable assembly prongs and ground.
• When connection leads are used:
With the megohmmeter, measure the insulation resistance between
each core lead and the ground lead.
Reference insulation resistance: 20M
Ω
or greater
Note: The reference insulation resistance (20M
Ω
or greater) is the
value when the pump is new or has been repaired. For the reference
value after installation, see “Periodic Maintenance Table.”
DO NOT measure the insulation resistance with insulation resistance
tester for the following parts. It will cause damage (Model PSA 2 500).
Improper ways to measure insulation resistance
1 Between the plug prongs.
2 Between the electrodes on the level relay unit.
3 Between the electrodes on the level relay unit and the plug prongs.
