E61-283-00
Operating Instructions
English translation
Errors and technical changes reserved
At A1-A2 connect the supply voltage
The internal alarm contact switches the voltage from A1
to terminal 14.
The voltage on the fault alarm inputs S1-S5 ist the same
as the supply voltage.
External fusing (6 A) of the output contact 14 must be
provided.
A line cross section of 2.5 mm
2
must not be exceeded
If the 24 V version is used, a safety transformer accord-
ing to EN 61558-2-6 or a power supply unit with electrical
isolation from the mains must be connected.
If the device does not function after commissioning, it must
be returned to the manufacturer unopened. Opening the
device will void the warranty.

Maintenance
The device must be checked once per month for proper-
function and for signs of tampering.
The device is otherwise maintenance free, provided that it
was installed properly.
