8.1
General
Carry out an overall check, making particularly sure that the
gear reducer is fi lled with lubricant.
Where Y-Δ starting is being used, input voltage must match the motor lower voltage (Δ connection).
For asynchronous three-phase motor, if the direction of rotation is not as desired, invert two phases at the terminals.
8.2
Running-in
It is advisable to execute a running-in of approximately 200 ÷ 400 h so that it is possible to achieve maximum functionality. The
temperature of both gear reducer and lubricant may well rise beyond normal values during running-in. After the running-in period
it may be necessary to verify the gear reducer fi xing bolt tightness.
