Electrical Wiring Work
WARNING
• All electrical work must be performed by an authorized electrician,
in compliance with local electrical equipment standards and internal
wiring codes. Never allow an unauthorized person to perform electrical
work because it is not only against the law, but it can also be extremely
dangerous.
• Improper wiring can lead to current leakage, electrical shock, or fire.
• Abusolutely provide a dedicated earth leakage circuit breaker and a thermal
overload realy 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.
Operate well within the capacity of the power supply and wiring.
Grounding
WARNING
Be sure to install the ground wire securely. Failure to observe this precaution
could damage the pump and cause current leakage, which may lead to
electrical shock.
CAUTION
Do not connect the ground wire to a gas pipe, water pipe, lightning rod, or
telephone ground wire. Improper grounding could cause electrical shock.
Connecting the Power Plug
WARNING
Before inserting the power plug or connecting the wires to the terminal
board, make sure that the power supply (i.e. circuit breaker) is properly
disconnected. Failure to do so may lead to electrical shock, short, or injury
caused by the unintended starting of the pump.
CAUTION
Do not use damaged cabtyre cables, power plugs, or loose power outlets.
Failure to observe this precaution could lead to electrical shock, short circuit,
or fire.
When a single-phase power source is used,
connect the leads to the control panel termi-
nals as shown in the diagram, making sure
they do not become twisted together.
When a three-phase power source is used,
connect the leads to the control panel termi-
nals as shown in the diagram, making sure
they do not become twisted together.
