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.”

Electrical Wiring
Performing electrical wiring
Electrical wiring should be performed by a qualified person in accord
with all applicable regulations. Failure to observe this precaution not
only risks breaking the law but is extremely dangerous.
Incorrect wiring can lead to current leakage, electrical shock or fire.
Always make sure the pump is equipped with the specified overload
protectors and fuses or breakers, so as to prevent electrical shock from
a current leak or pump malfunction.
Operate within the capacity of the power supply and wiring.
Grounding
Do not use the pump without first grounding it properly. Failure to
ground it can lead to electrical shock from a current leak or pump
malfunction.
Do not attach the grounding wire to a gas pipe, water pipe, lightning
arrester or telephone grounding wire. Improper grounding can result in
electrical shock.
