Terminals
and wiring
The screw terminal to facilitate all input and
output connections are located on the rear panel
of the annunciator case. Each screw terminal
can accommodate one or two max. 2.5 mm
2
wires. No terminal lugs are needed.
A connection diagram is attached to on one of
the side surfaces of the annunciator case.

Important 1
Make sure that the connected auxiliary supply
voltage complies with the specification. If two
auxiliary supply voltages are used, both voltages
are to be in accordance with the specified supply
voltage range.
Also make sure that the Protective ground (22)
is properly wired.
Important 2
If the annunciator is powered from two separate
auxiliary voltage sources, the supply networks
must be galvanically separated e.g. with an iso-
lating transformer if the customer does not
accept that the supply networks are galvanically
interconnected.
