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.
• Absolutely provide a dedicated earth leakage circut 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.
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.
Follow the diagram on the right to connect the power.
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.
When a three-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.

When using a three-prong grounded plug,connect as shown in the drawing.
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.
(This drawing shows a 2-pin plug type.)
5 ELECTRICAL WIRING
CAUTION Beware that the power plug
varies by country or region.
Note:
The cabtyre cable, if it is unused, is termi-
nally processed. If there is a need to peel
off the cable again, have the terminal pro-
cessed.
