1.7.3 Hazards due to unexpected movement of driven machinery
The motor shaft may start moving under certain conditions, e.g. when the supply voltage is switched
on or a holding brake is released. This way, the machinery driven by the drive can start to move
unexpectedly. This may result in severe injuries, also for third parties.
• Before switching on or releasing a brake, first secure the relevant hazard zone of the machinery
and make sure that there are no persons in the hazard zone.
1.7.4 Hazards due to loose parts
Loose parts may cause injuries to persons during transport, installation work or operation.
• Fasten or remove loose parts.
• Secure or remove free keys on the motor shafts.
1.7.5 Hazards due to high or low temperatures
The motor may heat up to 70°C during operation. Risk of burns on contact with hot surfaces. At very
low ambient temperatures freezing may occur on contact.
• Only touch the motor when wearing gloves after operation or at very low ambient temperatures.
• Before starting maintenance work, allow the motor to cool down sufficiently after operation.
• Provide a contact guard if there is a risk that persons may touch the drive when it is in operation.
• Do not place any flammable materials on the drive.
1.7.6 Hazards due to noise
Some motors or attached components may cause hazardous noise levels during operation. Wear
hearing protection if work has to be carried out close to such drives.
