Danger to life if the fundamental safety instructions and remaining risks are not carefully

If the fundamental safety instructions and remaining risks in Chapter 1 (Page 25) 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 as well as fire hazard due to overcurrent protective

devices that trip too late

Overcurrent protective devices that do not trip or trip too late can cause an electric shock or

• To protect personnel and for fire protection purposes, at the infeed point, the short-

Danger to life through electric shock due to a high DC link voltage

As long as the Line Module is connected to the line supply, the DC link is charged with a

high voltage. Contact with components can result in death or serious injury.

• Isolate the Line Module from the line supply during installation or maintenance work,

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.
