Electrical installation
6.3 Forced ventilation unit
PMCtendo SZ synchronous servo motors offer the option of being cooled with a forced ven-
tilation unit in order to increase performance data while maintaining the same size.
Retrofitting with a forced ventilation unit is also possible in order to optimize the drive at a
later date. When retrofitting, check whether the conductor cross-section of the power cable
of the motor must be increased.
The following plug connection for the connection of the forced ventilation unit is included in
the scope of delivery.
