If not, it can cause injury from electric shock.
Be sure to ground
Danger of restart
Be sure to switch off electric source before maintenance or inspection.
Single-phase motor has a thermal protector.
Vacuum pump restarts become cool without warning after vacuum pump.

must be provided.
Min. circuit ampacity of conductor is
1-phase 10A /3-phase 7A
Max. branch circuit breaker is 15A
When you used this pump in Europe or UK.
This vacuum pump must be equipped with a main disconnect device in accordance with requirements of EN/BS
EN 60204-1, clause 5.3.2. It is recommended to use a circuit breaker as main breaker which is suitable for

position and complies with the other requirements of EN/BS EN 60204-1, clause 5.3.
CAUTION
Motor burnout
Before doing any wiring, check electric source and voltage.
Single-phase is a multi voltage type of AC100V/AC200V. Three-phase is a multi
voltage type of AC200V/AC400V.
Voltage can be changed at terminal block.
This pump is wired to 200V when shipping from factory.
Check your electric source, voltage, and cord correctly to terminal block.
Improper wiring and incorrect voltage can cause motor burnout.
Check voltage
Danger of problem recurrence and failure
If protective device or thermal protector activates, be sure to turn off electric
source and inspect causes to solve the problem.
Do not operate until problem is solved.
Operation while problem is left unsolved can cause problem recurrence and failure.
