Safety information

Risk of electric shock
A hazardous voltage is still present for up to 5 minutes after the power supply has been
switched off.
It is only permissible to open the protective cover after this time has expired.
A suitable tool (e.g. screwdriver or the unlocking tool supplied) must be used to open the
protective cover of the DC link.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used further, otherwise this could result in secondary
damage or accidents.
A DC-link discharge voltage danger notice in the relevant national language must be
attached to all of the components.
A set of labels in 16 languages is supplied with the component.
With a connected braking resistor, the Braking Module is ground-fault proof.
CAUTION
The connection to the braking resistors must be made using a shielded cable.
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
The DC link lateral covers are supplied as standard with the components; they can also be
ordered separately, if required (order no.: 6SL3162-5AA00-0AA0).
The cooling clearances of 80 mm above and below the components must be observed.
Note
If braking resistors other than 6SN1113-1AA00-0DA0 and 6SL3100-01BE31-0AAx as
described in Chapter "Braking resistors for Braking Modules", are used then these could be
destroyed.
