IMPORTANT
① Use crimping terminals for the connection and tighten screws.
Check also screws fixing the connector tighten.
② Motor rotation direction is clockwise viewed from the motor side.
Refer to the arrow mark castled on the Motor flange
③ Be sure also to put a safety circuit such as
MCCB(Molded Case Circuit Breaker),
MC(Magnetic Contactor) and THR(Thermal Relay)
for the electrical connection.
④ Ensure to have a correct grounding.
You have a risk of getting electrical shock in case of failure or electric
leakage.
You are recommended further to install a dedicated earth leakage
breaker.
⑤ Minimize the length of the ground wire
⑥ Wire size, please determined by consideri
ng the voltage drop of the
wire.
Typically, the voltage drop, please to be within 2% of the rated voltage
of the motor.
Voltage drop calculation：
√3 × wire resistance (Ω / km)×Wiring length (m) × motor rated current (A) × 10
-3
※ motor rated current, refer to "Table 4".
WARNING
Install and operate this product
in compliance with the laws and
regulations relating to the safety, e.g. Fire Defense Law, Electric wiring
regulation and so on. In the country and region you use this product.
IE3 motor is used for this pump.
Striking current
tends to be high because efficiency of IE3 motor is higher
than conventional motor. Because of this consequence
momentary operation by striking current of the motor in the case of
current set rating of MCCB (Molded Case Circuit Breaker), ELCB (
Leakage Circuit Breaker) and THR (Thermal Relay).
It is required to readjust setting of MCCB, ELCB and THR.
