10.2 Voltage Protection Module VPM
Danger to life through electric shock when using third-party motors
VPM can be used with third-party motors. If, when using third-party motors, the VPM does
not limit the DC link voltage, this can result in death or severe injury.
• Please observe the following when using third-party motors:
Danger to life through automatic start of the drive
An uncontrolled automatic start of the drive can result in fatal accidents.
• Take precautions against an automatic start of the drive.
NOTICE
Damage when using motors that are not short-circuit proof
Use of motors that are not short-circuit proof in conjunction with a Voltage Protection
Module can result in their destruction.
• Only use motor that are short-circuit proof.
Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. This can also result in more downtimes and reduced service
lives of components.
• Maintain the 200 mm clearances above and below the components.
NOTICE
Damage to devices as a result of incorrect connecting cables
Using incorrect connecting cables for Voltage Protection Modules can damage the
connected components.
• Use shielded MOTION-CONNECT 800PLUS motor cables, type 6FX8.

WARNING
– Carry out a risk analysis.
– Ensure that the third-party motors correspond to the electrical properties of the
specified Siemens components.
– Check the correct functioning of the VPM.
