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.
