Danger
Securely connect the terminals of the power cable. Loose terminals may
cause an open phase fault, which causes the motor to burn out.
(1) For the size of the power cable, refer to the following:
Type
Minimum size of the cable
(200-volt class)
All types 1.6mm
(2) Be sure to install a ground fault interrupter and an overload protection device on the primary
power side of the pump.
* The starting current of the Top Runner Energy Efficiency Standards (equivalent to IE3)
motor-equipped product tends to become higher than that of the standard efficiency (IE1)
motor-equipped product. Therefore, it is necessary to apply and verify an earth leakage circuit
breaker and overload protection device on the occasion of replacement from the IE1
motor-equipped product. (Refer to the startup current and the rated current in 2.5 “Specification
table” .page 2-3.)
If you have any questions, please contact us.
Note
It is necessary to apply and verify a protective device on the primary side of
the pump on the occasion of replacement from the IE1 motor-equipped
product.
If not applied, the protective device may operate at the time of startup.
(3) When connecting to terminals, securely connect to the power according to the below figure.
(Standard voltage product)
* If there are four or more terminals, follow the connection nameplate in the terminal box.

(4) Be sure to attach a ground wire to prevent an electric shock.
Connect the ground wire to the ground terminal inside the control panel.
Warning
Connecting a ground wire to gas or water pipes is illegal
and extremely dangerous.
