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 4" and "Table 3."
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
(Gauge pressure).
Do not operate the Pump in hazardous area (where there is a risk of
creating hazardous atmosphere by explosive gas). It might cause
injury and/or fire.
Be sure to turn OFF the Power Supply to execute check and repair.
You have a risk of getting electrical shock or injury by accidental
