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

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.

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

circuit rating and loop impedance must correspond to the specifications in the

documentation in order for the installed overcurrent protection devices to trip within the

specified time.

e.g. via the line contactor or main switch.
