Safety instructions for DC link adapters
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 27) 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 due to the residual charge of the DC link capacitors
Because 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 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 incorrectly installed DC link bridges
Incorrectly installed DC link bridges
at the left-hand end of the drive line-up
can cause an
electric shock.
• For all 50 mm wide modules
1)
(exception: Smart Line Module
2)
), remove the DC link
bridge, including the screws. Do not tighten the screws without the DC link bridges.
• For all components that are 75 mm wide or wider, the DC link bridges may neither be
swung over to the left nor removed
3)
.
1)
For 50 mm wide modules, the DC link bridge cannot be swung inwards.
2)
Smart Line Modules do not have a DC link bridge.
3)
The DC link bridge guarantees the mechanical stability of the DC link busbars.
