Safety Information

Danger
A hazardous voltage is present for 5 minutes after the power supply has been disconnected.
The adapter cannot be installed until this time has elapsed.
When opening the protective cover for the DC link, you must activate the release. A suitable
tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used, otherwise this could result in secondary damage
or accidents.
Danger
Components for which the recesses for the DC link supply adapter have been removed must
no longer be operated without them. If components need to be operated without neither the
recess nor DC link supply adapter, the DC link cover must be replaced.
Caution
The DC link discharge voltage hazard warning on the modules on which the adapter is
installed must be in the local language.
A set of labels in 12 languages is available using order number: 6SL3166-3AB00-0AAx.
Caution
The screw tightening torque (1.8 Nm, tolerance: +30%) for securing components to the
module-side DC link busbar must be checked before commissioning to ensure that it is
correct. After transportation, the screws must be tightened.
Caution
To ensure safe electrical separation, the 24 V supply cables and those for the DC link
connection cables must be physically separated (> 100 mm), or the 24 V cables must be
doubly insulated (e.g. light plastic-sheathed cable).
Warning
The DC link connection cables must be routed in such a way as to ensure that they are
ground-fault and short-circuit proof in accordance with DIN/VDE 0100 or suitable fuse
protection must be provided.
Caution
The total length of the DC link (including the connection cables) must not exceed 10 m.
