Safety instructions for Power Modules

Danger to life if the fundamental safety instructions and residual risks are not observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Observe the fundamental safety instructions.
• Consider the residual risks for the risk evaluation.
Danger to life due to electric shock caused by residual charge of the DC-link capacitors
Due to the DC-link capacitors, a hazardous voltage is present in the DC link for up to five
minutes after the power supply has been switched off.
Touching live components results in death or severe injury.
• Only carry out work on these components after this time has elapsed.
• Measure the voltage before starting work on the DCP and DCN DC-link terminals.
Danger to life through a hazardous voltage when connecting an unsuitable power supply
Death or serious injury can result when live parts are touched in the event of a fault.
• Only use the intended supply voltage to operate the Power Modules.
Danger to life due to electric shock caused by not covered terminals (for frame sizes FSD
to FSF)
Contact with live terminals can cause death or severe injury.
• Before starting the connection work, ensure that the Power Module is de-energized.
• After connecting the supply and motor cables to the appropriate terminals, reattach the
• Only connect the Power Module to the supply voltage after these checks have been
