Safety instructions for Control Supply Modules

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 when live parts are touched when using the control supply module
The Control Supply Module has 2 supply circuits. Death or serious injury can result when
live parts are touched.
• Switch off both supply circuits before you start any work.
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 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 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 on the first and last component in the drive line-up.
• Order any missing side covers (Article number: 6SL3162-5AA00-0AA0).
