Switching on with the anti-condensation heating active

NOTICE
Excessive machine temperature
If the anti-condensation heating is operated while the machine is running, this can increase
the temperatures inside the machine. This can result in material damage.
● Make sure that the anti-condensation heating is switched off before the machine is
● Only operate anti-condensation heating when the machine is switched off.

Switching on the machine

1. If at all possible, run the machine without load and check that it is running smoothly.
2. If it runs perfectly, connect a load.
3. If this is possible using the available measuring equipment, check the bearing and stator

NOTICE
Thermal overload of motors connected directly to the line supply
In addition to the load torque, the ramp-up (accelerating) time is essentially influenced by
the moment of inertia to be accelerated. While ramping up when connected to the line
supply, the inrush (starting) current is a multiple of the rated current. This can result in
thermal overload. This can damage the motor.
As a consequence, when ramping up, observe the following:
● Monitor the ramp-up time and number of consecutive starts.
● Comply with the limit values and/or ramp-up conditions specified in the catalog or the
order documentation.
