GENERAL SAFETY RULES
Before installation, read the instruction manual to avoid errors that can
damage the device and give you an electric shock.
Before installation, cut off voltage in 230 V power-supply circuit.
To switch power off, use an external switch, in which distance between contacts of all poles
in disconnection state is not less than 3mm.
The shock protection circuit shall be done with a particular care: the yellow and green wire
coat of the power cable should be connected to the terminal marked with the grounding
symbol on the PSU enclosure. Operation of the PSU without the properly made and fully
operational shock protection circuit is UNACCEPTABLE! It can cause damage to the
equipment or an electric shock.
Device should be transported without batteries. This has a direct impact on safety of user
and device.
Installing and connecting power supply must be carried out without batteries.
When connecting batteries to power supply, pay particular attention to correct polarity.
If necessary, it is possible to permanently disconnect battery from power supply systems by
removing FBAT fuse.
Power supply is adapted to be connected to a power distribution network with an effectively
earthed neutral conductor.
Ensure a free, convection air flow around the enclosure. Do not cover ventilation openings.

3 Installation.
3.1 Requirements.
Power supply units is to be mounted by a qualified installer, holding relevant permits and licenses (required in
installation country) to connect (interfere) with ~230 V mains supply.
Because power supply units is designed for the continuous operation and is not equipped with ON/OFF switch,
the power supply circuit should have the appropriate overload protection. Moreover, the user shall be informed about
the method of unplugging (most frequently through separating and assigning an appropriate fuse in the fuse-box).
The electrical system shall follow valid standards and regulations. The PSU shall work in a vertical position that
guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
As PSU cyclically runs a periodic battery test, during which resistance in battery circuit is measured, pay
attention to proper connection of cables to terminals. Installation cables should be firmly connected to battery side
terminals and to power supply connector. If necessary, it is possible to permanently disconnect battery from power
supply systems by removing FBAT fuse.
3.2 Installation procedure.
CAUTION!
Before installation, cut off voltage in ~230 V power-supply circuit.
To switch power off, use an external switch, in which distance between contacts
of all poles in disconnection state is not less than 3mm.
It is required to install in the supply circuits, in addition to power supply, circuit breaker with 6 A
nominal current.
1. Mount the PSU in a selected locatio.
Connect power cables ~230 V to L-N clips of PSU. Connect ground wire to clip marked by earth symbol .
Use a three-core cable (with a yellow and green protection wire ) to make connection.
Wires should be deisolated to a length of 7mm.
Shock protection circuit shall be done with a particular care: yellow and green wire coat of
power cable should be connected to terminal marked with grounding symbol on PSU enclosure.
Operation of PSU without properly made and fully operational shock protection circuit is
UNACCEPTABLE! It can cause damage to equipment or an electric shock.
2. Connect receivers’ cables to AUX output terminals.
3. If needed, connect cables from devices to technical inputs and outputs:
- APS; technical output of battery failure
- EPS; technical output indication of 230 V power collapse (alarm control panel, controller, indicator, etc.).
- PSU; technical output of collective failure of PSU
- EXTi; input of external failure
- TAMPER; contacts of antisabotage protection
4. Install battery/batteries in a designated area of enclosure. Connect batteries with PSU paying special attention to
correct polarity and type of connections (Fig. 4):
a) b)
Fig. 4. Connecting batteries depending on voltage version of power supply:
a) ) power supplies 12V version, b) power supplies 24V version

5. Screw terminals of temperature sensor to "Temp" terminals of PSU (figure 2, point 6). Attach sensor to battery,
e.g. with adhesive tape. For the 27.6 V version, it is recommended to place sensor between batteries.
6. Switch on ~230 V supply. The corresponding LEDs on the power supply PCB should be ON: green 230 V AC
and above AUX connectors.
7. Check current consumption of receivers, taking into account battery charging current, so as not to exceed total
current efficiency of PSU (see section 2.1).
8. Once the tests and control operation have been completed, close the enclosure.
3.3 Procedure for checking power supply module on installation site.
1. Check indication displayed on printed circuit board of power supply:
a) 230 V AC LED should remain lit to indicate presence of mains supply voltage.
b) LED above AUX connectors lights up to indicate presence of output voltage.
2. Check output voltage after 230 V power failure.
a) Simulate lack of 230 V mains voltage by disconnecting main circuit breaker.
b) 230 V LED should go out.
c) LED above AUX connectors lights up to indicate presence of output voltage.
d) LED ALARM LED will start blinking.
e) EPS technical outputs will change status into opposite after time 11 s.
f) Turn on 230 V mains voltage again. Indication should return to initial status from point 1 after about
11 seconds.
3. Check whether lack of continuity in battery circuit is properly indicated.
a) During normal PSU operation (230 V mains voltage on), disconnect battery circuit by disconnecting FBAT fuse.
b) Within 5 minutes PSU will start signalling a failure in battery circuit.
c) LED ALARM LED will start blinking. APS technical output will change status into opposite.
d) FBAT fuse in battery circuit again.
e) Power supply should return to normal operation, indicating initial status, within 5 minutes after battery test is
completed.
