Operating Instructions
4 Mounting
• Mount the safety barrier onto a carrier rail
outside of the hazardous area
• Connect the potential equalisation cable
from the Ex-area to the projecting PA-termi-
nal
• Connect the intrinsically safe circuit (blue)
correctly to the blue-coloured side of the
safety barrier. Note the polarity.
• Now connect the non-intrinsically safe circuit
correctly to the upper white-coloured side of
the safety barrier. Wrong polarity will de-
stroy the safety barrier.
Note:
Cables in Ex-areas must have a durable blue
marking along their entire length.
