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:
– 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.
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.
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.
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.
