Electrical installation
During the electrical installation of the C4000 – ATEX II 3G/3D safety light curtain, observe
the following notes in addition to the information in the underlying operating instructions.
The rated voltage must not be exceeded!
When used in an explosion-protected area, special requirements apply to the power
supply:
Ensure that the rated voltage cannot be exceeded by more than 40 %, even in the case
of temporary faults. At a maximum permitted supply voltage of 28.8 V, 40.3 V must not
be exceeded.
Only disconnect the electrical connections of the device when power is switched off!
On the disconnection of parts carrying electrical power, sparks may be produced. This will
result in a serious risk of injury in an explosive area.
Always first switch off the power supply before you disconnect a connection cable from
the device.
Ensure that all electrical connections are made to the device or the connections are
protected!
The IP enclosure rating for the connections and thus the device is only guaranteed when
the connections are protected. Otherwise foreign objects may enter the connection
chamber. This could cause an explosion the next time the device is switched on.
Ensure that all electrical connections are always made and screwed tight.
Or:
Screw the protective cap attached to the device onto the electrical connection and
tighten if the connection is not used.
In any case take appropriate technical precautions to maintain the IP enclosure rating of
the connection cables.
