Safety instructions for the hardware
WARNING
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
● Comply with the fundamental safety instructions.
● When assessing the risk, take into account residual risks.
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.
WARNING
Danger to life through electric shock due to incorrectly installed DC link clips
Incorrectly installed DC link clips at the left-hand end of the drive line-up can cause an electric
shock.
● For all 50 mm wide modules (exception: Smart Line Module) remove the DC link clips,
including the bolts. Do not tighten the screws without the DC link clips.
● For all components that are 75 mm wide or wider, it is not permissible that the DC link
clips are moved to the left or removed.
WARNING
Danger to life through electric shock due to missing DC link side covers
There is a danger of an electric shock through contact when the side covers of the DC link
are missing.
● Mount the side covers that are provided on the first and last component in the drive line-
up.
● Order any missing side covers (order number: 6SL3162-5AA00-0AA0).
