3.5 Fluctuations in the power voltage
Standard: General rules for rotating electrical machines
IEC 60034-1:2004
To the voltage change in Domain A, in main rated values, it operates continuously, and can
be used practically convenient, and to the voltage change in Domain B, it shall operate with
main rated values and shall be used practically convenient.
However, operation with "it is convenient and safe is maintained on "practical use, it means
not resulting in the grade which shortens a life remarkably, and the characteristic, a
temperature rise, etc. do not apply correspondingly in the state of rating. Moreover, main
rating shows rated torque (N
･
m).

(It applies only to the voltage)
3.6 Checking Operation After Installation
１）
Make sure that power is turned “OFF” before connecting the power cord to a power source that meets
the voltage requirement for motor.
Caution: Always use a power cord that meets the voltage and current requirements.
２）
Turn “ON” the power to check that the vacuum pump is working.
３）
After the pump has been checked, turn “OFF” the power.
