Safety Information

Danger
Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the power
supply has been disconnected.
This time must elapse before any work may be carried-out on the adapter (e.g. mounting/
installation).
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.
