4.4 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
arrestor or telephone grounding wire. Improper grounding can result in
electrical shock.
Cable Assembly
If it is necessary to extend the cable assembly, use a core size equal
to or larger than the original. This is necessary not only for avoiding a
performance drop, but to prevent cable overheating which can result in
fire, electrical leakage or electrical shock.
If a cable with cut insulation or other damage is submerged in the
water, there is a danger of damage to the pump, electrical leakage,
electrical shock, or fire.
Be careful not to let the cable assembly be cut or become twisted. This
may result in damage to the pump, electrical leakage, electrical shock,
or fire.
If it is necessary to submerge the connection wires of the cable
assembly in water, first seal the wires completely in a molded
protective sleeve, to prevent electrical leakage, electrical shock, or fire.
DO NOT allow the cable assembly wires or power supply plug to
become wet.
Make sure the cable does not become excessively bent or twisted, and
does not rub against a structure in a way that might damage it.
If used in a deep-well installation, the cable assembly should be
secured every twenty feet.
