Danger to life through electric shock due to the 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.
Contact with live parts can result in death or serious injury.
• Do not open the protective cover of the DC link until five minutes have elapsed.
• Check that the cabinet is de-energized.
Note
Line Modules are formed by means of a connected Motor Module. See Forming circuits of
