Safety information

Warning
After disconnecting all the supply voltages, a hazardous voltage will be present in all
components for another 5 minutes. The protective cover must not be opened until this time
has elapsed.
The DC link protective cover must be released using an insulated screwdriver.
Caution
The DC link discharge time hazard warning must be affixed to the modules in the local
language.
A set of labels in 12 languages is available using order number: 6SL3166-3AB00-0AAx.
Notice
The 80 mm clearances above and below the components must be observed.
Caution
The tightening torque of the DC link busbar screws (1.8 Nm) must be checked before
startup.
Danger
In addition to the line module, the control supply module must be disconnected from the
supply system to electrically isolate the DC link from the supply network.
If a selectively tripping AC/DC-sensitive residual-current circuit-breaker is used, the control
supply module must be connected downstream of this.
