Danger!
Explosion hazard from live wiring of non-intrinsically safe circuits
If you connect or disconnect energized non-intrinsically safe circuits in a potentially
explosive atmosphere, sparks can ignite the surrounding atmosphere.
Only connect or disconnect energized non-intrinsically safe circuits in the absence
of a potentially explosive atmosphere.
Danger!
Explosion hazard from wrong mounting
The device safety can be impaired by external environmental influences and
by mechanical stress. That can lead to sparking that can ignite a surrounding potentially
explosive atmosphere.
Mount the device in a surrounding enclosure that complies with IEC/EN 60079–0
and that is rated with the degree of protection IP54 according to IEC/EN 60529.
CORRECT: Device snapped on vertically.
INCORRECT: Device snapped on from the side.
Can damage the contacts and cause the device to fail.
