3.Wiring
3.1 Junction box
Permanent magnet motors need to be driven by permanent magnet motor drives. The
name of each contact is marked inside the T-box. Please follow the correct marking for wiring
connection.

3.2 Rotating direction
(1)
Please confirm if the rotating direction is correct.
(2)
The rotating direction of the motor is confirmed by observation from shaft end direction
at load side; if change of rotating direction is desired, please adjust it from the drives.
(3)
Please confirm that the airflow direction of cooling fan is from the fan side toward the
motor side (shaft end).
3. Commissioning and operation
1.Before operation
All motors have been strictly tested prior to their ex-factory; however, owing to the
possible impacts arising from long-term storage or transportation against motor status,
please check and validate motor status before use.
(1)
Precautions before commissioning:
Are power supply wirings correctly connected? Is external cover of T-box
normally accessorized and locked?
Are anchor bolts loosened?
Is there any improper ventilation condition?
Is there occurrence of contact friction problem between rotating parts and
stationary parts when manually rotating the shaft end?
