Coolant piping <Mounting>
Check and ensure that any of hazardous energy is blocked before starting
the operation.
Power Supply wiring <Mounting>
Check and ensure that any of hazardous energy is blocked before starting
the operation.
Entitled staff should conduct the wiring operation. Erroneous wiring work
might cause a fire.
Conduct the wiring operation correctly in compliance with laws and rules
concerning the safety (e.g. Fire Defense Law, Electric Equipment
Technology standard, Internal line cord) in the country and region you use
the product.
Ensure to have a correct grounding.
You are recommended further to install a dedicated Leak breaker. You
have a risk of getting electrical shock in case of failure or electric leakage.
It is imperative to put the Overload protection device. Otherwise it would
cause the motor burn out and/or fire.
Wire size, please determined by considering 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 2".
Operation
Do not run the Pump on blocking the exhaust outlet or putting any device
that might hamper gas passage onto the outlet. There is a risk that the
pressure inside the Vacuum pump rises up to cause break or oil leak of
the casing or Oil level gauge resulting in overload of the motor.
This product is not made as the withstand pressure structure. Ensured
pressure value of the Pump shall be 0.03MPaG (0.3kg/cm
2 G) (Gauge
pressure).
