- relay type: 1A@ 30VDC/50VAC, time lag: approx. 10s.
- OC type, 50mA max., normal status: L (0V) level, failure: hi-Z level, time
lag: 10s.
CAUTION! In Fig.2. the contact set in the potential-free status
corresponds to a state with no AC power (AC power failure).
- OC type, 50mA max., normal status: L (0V) level, failure: hi-Z level

LED indication :
- presence of AC power
–
presence of DC voltage at the
PSU output
- battery voltage level
-red LED (fig.1, element 1).
Under normal status (AC supply) the diode
is permanently illuminated. The absence of AC supply is indicated by
the AC diode going out.
Caution: the LED indicates absence of AC power if the loss lasts minimum
10s.
-green LED (fig.1, element 2)
indicates DC power at the PSU output.
Under normal status the diode is permanently illuminated. In case of a
short circuit or an overload, the diode is off.
- green LED (fig.1, element 3)
indicates battery voltage level. Under
normal status (U
BAT
> 23V) the diode is permanently illuminated. In
case of decrease of battery voltage (U
BAT
< 23V) the diode is off.

2.1. Requirements.
The module is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for 230V/AC interference and low-voltage installations. The unit should be mounted in
confined spaces, in accordance with the 2nd environmental class, with normal relative humidity (RH=90% maximum,
without condensation) and temperature from -10°C to +40°C.
The module shall be mounted with a PSU of PSB 27,6V series in a metal enclosure (cabinet, intended device). In
order to fulfil LVD and EMC requirements, the rules for: power-supply, encasing and screening shall be followed,
according to application.
It is crucial to connect the PE wire to the appropriate PSU terminal.
2.2. Installation procedure.
1. Before installation of the module, make sure that the PSB 27,6V PSU supplying LEDs are disconnected from the 230V
AC mains supply.
2. Mount the module on the PSB 27,6V power supply unit.
3. Cut the BAT+, BAT- leads in the PSB 27,6V PSU, separate and connect to the module, following the diagram. (fig.2).
4. Cut the leads of the signal connector in the PSB 27,6V power supply unit, separate and connect to the module,
following the diagram. Connect the Lac, Ldc, GND leads of the PSU with appropriate outlets on the automation module.
(see fig. 4).
5. Connect the technical outputs of the other device.
6. Connect the 230VAC power cables. Connect the PE cable (yellow-green) to the appropriate PSU terminal (marked with
- earth symbol).
