In the case of "increased safety" terminal boxes, make sure to comply with the clearances specified in EN 50019
between conductive parts having different potentials. Tighten the screws and nuts on the live parts to the specified
torque.

Depending on the model, additional terminals for instance for temperature monitoring or space heater are located
either in the main terminal box or in additional terminal boxes; see the supplied wiring diagram.
Please note!
Take note of the rating data imprinted on the terminals.
Please note!
Keep the wiring diagram supplied in the terminal box in the enclosure with the documents belong-
ing to the drive.
Motors with unidirectional fan
Make sure that the fan's direction of rotation matches that of the motor.
Motors with separate cooling via separately powered external fans
Make sure by means of the electric control that the main motor can be operated with the motor switched-on for sepa-
rate cooling.
