3.5 Electrical Connection
IMPORTANT
Conduct the electrical connection referring to the “Fig.4”,
“Fig.5”, “Fig.6” and “Table.7”.
Use crimping terminals for the connection and tighten screws.
Check also screws fixing the connector tighten.
Motor rotation direction is clockwise viewed from the motor side.
Refer to the pump’s nameplate.
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.
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.
Minimize the length of the ground wire
Wire size, please determined by considering the voltage drop of the wire.
WARNING
Install and operate the 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
the
product.
WARNING
PMB300D, 600D, 1200D, 2400D has adopted the IE3 motor.
※ PMB100D has adopted the IE2 motor.
Striking current
tends to be high because efficiency of IE3 motor is
higher than conventional motor. Because of this consequence
, there
could be momentary operation by striking current of the motor in the
case of current set rating of MCCB (Molded Case Circuit Breaker
),
ELCB (Earth Leakage Circuit Breaker) and THR (Thermal Relay).
It is required to readjust setting of MCCB,
ELCB
and T
HR
.
CAUTION
The motor protection of PMB1200D and PMB2400D (thermal), we
will recommend the lagged type.
