WARNING
Active implant malfunctions due to permanent-magnet fields
Even when switched off, electric motors with permanent magnets represent a potential
risk for persons with heart pacemakers or implants if they are close to
converters/motors.
• If this affects you, maintain the minimum distance to such equipment that is
specified in the "Intended use" chapter.
• When transporting or storing permanent-magnet motors always use the original
packing materials with the warning labels attached.
• Clearly mark the storage locations with the appropriate warning labels.
• IATA regulations must be observed when transported by air.
WARNING
Injury caused by moving or ejected parts
Contact with moving motor parts or drive output elements and the ejection of loose
motor parts (e.g. feather keys) out of the motor enclosure can result in severe injury or
death.
• Remove any loose parts or secure them so that they cannot be flung out.
• Do not touch any moving parts.
• Safeguard all moving parts using the appropriate safety guards.
WARNING
Fire due to inadequate cooling
Inadequate cooling can cause the motor to overheat, resulting in death or severe injury
as a result of smoke and fire. This can also result in increased failures and reduced
service lives of motors.
• Comply with the specified cooling requirements for the motor.
WARNING
Fire due to incorrect operation of the motor
When incorrectly operated and in the case of a fault, the motor can overheat resulting
in fire and smoke. This can result in severe injury or death. Further, excessively high
temperatures destroy motor components and result in increased failures as well as
shorter service lives of motors.
• Operate the motor according to the relevant specifications.
• Only operate the motors in conjunction with effective temperature monitoring.
• Immediately switch off the motor if excessively high temperatures occur.
