The DC link busbars are located under the DC link cover.
DANGER
Danger to life through electric shock due to the residual charge of the DC link capacitors
As a result of the DC link capacitors, a hazardous voltage is present for up to 5 minutes after
the power supply has been switched off.
Contact with live parts results in death or serious injury.
● Do not open the protective cover of the device until 5 minutes have elapsed.
● Before starting any work, check that the system is in a completely no-voltage condition by
measuring all poles/phases, also to ground.
● Ensure that the associated warning plate in the appropriate language is attached.
