Safety information

Risk of electric shock
This component is equipped with two supply circuits! A hazardous voltage is still present for
up to 5 minutes after the power supply has been switched off. Only after this time has
expired may the protective cover be opened using a suitable tool.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components (e.g. with a defective lock on the protective cover) must not be
operated further. Secondary damage or accidents can otherwise result.
DC link discharge time
The hazard warning for the DC link discharge time must be attached to the component in
the local language.
A set of labels in 16 languages is supplied with the component.
The cooling clearances of 80 mm above and below the components must be observed.
CAUTION
The tightening torque of the DC link busbar screws (1.8 Nm, tolerance +30 %) must be
checked before commissioning. After transportation, the screws must be tightened.
CAUTION
DC link side covers are supplied with the components as standard and must be attached to
the last component in the S120 Combi drive line-up. They can also be ordered separately, if
required (order no.: 6SL3162-5AA00-0AA0).
CAUTION
Use of the 24 V terminal adapter
When using the 24 V terminal adapter, it must be screwed onto the Control Supply Module
using the EJOT PT K30 x 16 screw supplied (tightening torque: 0.5 Nm).
