3.20 Installing a fan (Option: FAN-A, FAN-R)
The fan wheel of a radial and axial fan is arranged on the high-speed shaft of the gear unit and
protected against accidental contact by a fan cover. The fan takes in air through the protective grill of
the fan cover. The lateral air baffles of the fan cover guide the air past the gear unit housing. Through
this, the air dissipates a specific amount of the housing heat.
An electrical external fan, which is driven by an external three-phase motor, is available as a special
option. For the correct installation and the electrical connection, refer to the manufacturer’s manual.
