for use in that area. Otherwise it must be installed in an area which is known to be non-hazardous.
WARNING
Opening the device
DO NOT OPEN WHEN ENERGIZED.
WARNING
Risk of explosion when connecting or disconnecting the device
EXPLOSION HAZARD
WARNING – EXPLOSION HAZARD - Do not connect or disconnect while circuit is live unless area is known to be non-
hazardous.
WARNING
Explosion hazard from sparks when connectors come loose
If a plug connector comes loose from the associated device interface during operation in a hazardous area, a spark over at
the interface may cause an explosion. Death or serious physical injury as well as property damage may result.
For use in hazardous areas, it must be ensured that the plug connectors of the cables are fully connected to the respective
interface and cannot come loose from the interfaces in any case.
Secure all connected cables directly at the transition between connector and cable to the nearest fastening point of the
strain relief plate or strain relief element using a cable tie. Tighten up all cable ties in such a way that they fully wrap
around the respective cable but do not damage the cable.
WARNING
Explosion Hazard
Batteries must only be changed in an area known to be non-hazardous.
The lithium battery shall only be replaced by a trained technician.
