Safe area
The pac-Bus is an accessory for the
isolating power supply. It consists of
pac-Bus elements (one per isolator) and
the terminal set (one per pac-Bus
segment).
The power supply is connected via the
terminals 1 and 2.
The signalization of line faults can be
read out via the terminal 3 and 4.
Please remove one of the jumpers
between terminal 3 and 4. Connect the
wire to the terminal. The line fault
signalization uses a potential free
contact in the isolator.
