WARNING
① Turn OFF the Power Supply to do the electrical connection.
Never try to work on it on keeping the electricity turned ON.
②
A correct wiring work must observe the law and the rule that relates
safely. A wrong wiring work might start a fire.
③
The measures such as lockout/tag out should be executed not so as to
turn the power switch by mistakes during working.
④
You have a risk of getting electrical shock when the machine caused a
failure or electrical leakage.
Make sure to have the steady grounding.
You are also recommended to install a dedicated earth leakage breaker.
The screw of the earth
terminal at the motor side is provided with an
“earth mark ” in the terminal box.
The diameter of the cable to connect to a ground is the same as a cable
supplying a power supply in a motor at least.
Be sure to ground the motor ground terminal
200V - 240V: Ground to 100ohm or less
380V - 460V: Ground to 10 ohm or less
⑤
Use a safety circuit which keeps the motor from starting a fire which is
caused by over current.
⑥ Install a safety circuit suitable for the capacity of the motor. If a
circuit is not installed, or if a safety circuit
that is unsuitable for the
motor capacity is installed, the motor will be damaged leading to fire.
⑦
The safety circuit must use the one that operates by the ratings current
value of the motor that uses it.
Do the setting of the sa
fety circuit in a rating current value of the motor
in line with the voltage and the frequency of the power supply.
When a motor is different from the standard, please do the setting of
the safety circuit in a rating current value of the motor you use.
⑧ Never fail to close the Terminal box cover to operate the Pump.
⑨
Do not use it excluding the voltage rating of the motor. It causes
damaging by a fire and a fire of the motor.
CAUTION
Do the Direct-in start connection.
