Operating instruction
4 Mounting
• Plug the safety barrier outside the hazard-
ous area to a C-rail.
• Connection the potential equalization line out
of the Ex-area to the PA-terminal.
• Connect the intrinsically safe circuit (blue)
correctly to position on the safety barrier
which is marked blue. Note the polarity.
• Now connect the not-intrinsically safe circuit
correctly to the upper side (white) of the
safety barrier. Wrong polarity destroys the
safety barrier.
Note:
Lines in Ex-areas must be marked blue along
their entire length.
