7.5 Commissioning an external fan
Machines of shaft heights 250 and 280 are shipped with the air-outlet grille of the external fan
motor for connection to a 50 Hz supply already fitted. The cover sheet ① for motors which
operate on 60 Hz is supplied as a motor accessory.
NOTICE
Operation on 60 Hz
In operation on a 60 Hz supply, the external fan motor can overheat or burn out. If you intend
to operate the external fan on a 60 Hz mains supply, then fit the cover sheet ① with the
screws provided under the air-outlet grille before you commission the motor.
