Safety instructions for DC link components

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 27) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Danger to life through electric shock due to the residual charge of the DC link capacitors
Because of the DC link capacitors, a hazardous voltage is present for up to five minutes
after the power supply has been switched off.
Contact with live parts can result in death or serious injury.
• Do not open the protective cover of the DC link until 5 minutes have elapsed.
• Measure the voltage before starting work on the DCP and DCN DC link terminals.
Danger to life through electric shock when the protective cover of the DC link is open
Contact with live parts can result in death or serious injury.
• Only operate the components with closed protective cover.
Danger to life through electric shock due to incorrect connection to the DC link
Incorrect connections can lead to overheating and therefore a risk of fire. There is also a
risk of an electric shock. This can result in serious injury or death.
• Only use adapters (DC link adapters and DC link rectifier adapters) released by
Booksize Power Units
