START-UP
Perform the following operations and checks before start-up:
1) check that all safety measures have been applied;
2) power up the motor unloaded at rated voltage;
3) check that the sepate fan cooling (if any) is operating;
4) check that operation is smooth and vibration-free;
5) If the brake is fitted, verify that it operates regularly;
6) if operation is satisfactory, apply the load to the motor while checking on values of absorbed cur-
rent, power and voltage.
Abnormal operations such as over current, overheating, noise, or vibrations, may cause seri-
ous damage or hazardous conditions. In these cases, cut power and notify maintenance per
-
sonnel immediately.
Switch-pole motors, nine pin motors (motors with voltage in ratio 2) and, at request, single-pole mo-
tors with separate power supply are equipped with an auxiliary terminal board with 6 terminals for
brake connection.
In this version, motors feature a larger terminal box.
