Safety instructions for Blocksize Power Modules (PM240-2)
Danger to life if the fundamental safety instructions and residual risks are not heeded
Failure to heed the fundamental safety instructions and residual risks in Chapter 1 can
result in accidents causing severe injuries or death.
• Follow the fundamental safety instructions.
• Consider the residual risks on the risk assessment.
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 5
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 due to hazardous voltage when an unsuitable power supply is connected
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.
