Performing electrical wiring
WARNING
• 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 electrical leakage, electrical shock or fire.
• Absolutely provide a dedicated earth leakage circuit breaker and a thermal
overload relay suitable for the pump (available on the market). Failure
to follow this warning can cause electrical shock or explosion when the
product fails or an electrical leakage occurs.
Provide an extra allowance in the capacity of power supply and wiring.
Grounding
WARNING
Do not use the pump without first grounding it properly. Failure to ground it
can lead to electrical shock from an electrical leak or pump malfunction.
CAUTION
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.
Connecting the power supply
WARNING
Before connecting leads to the terminal strip, make certain the power supply
is turned off (circuit breaker, etc.), to avoid electrical shock, shorting, or
unexpected starting of the pump, leading to injury.
WARNING
Before inserting the power supply plug, make certain the power supply
is turned off (circuit breaker, etc.), to avoid electrical shock, shorting, or
unexpected starting of the pump, leading to injury.
CAUTION
Do not use the product with the cabtyre cables or plug connected loosely,
which can result in electric shock, shorting, or fire.
CAUTION
Draw power from a dedicated power outlet having sufficient capacity for the
pump. Sharing the outlet with other equipment may cause overheating at the
branch outlet and could result in fire.
CAUTION
Be sure to use a dedicated
power supply with a ground
leakage circuit breaker.
Note:
The shape of the plug may differ from that
shown in the illustration.
When using a three-prong grounded plug, con-
nect as shown in the drawing.
When a single-phase power source is used, con-
nect the leads to the control panel terminals as
shown in the diagram, making sure they do not
become twisted together.
