1. Before installation make sure that the mains 230 V is disconnected.
2. Install the power supply at the selected place and evacuate connection wires.
3. Remove the main fuse protecting the transformer primary circuit [15].
4. Connect the supply conductors ~230V to the terminals of the transformer (AC 230 V). The earthing
conductor should be connected to the terminal marked with the grounding symbol. Three-wire cable
should be used for the connection (the protective conductor in green-and-yellow).
The power conductors should be connected to the appropriate terminals on board [14] [16] and
properly insulated.
Particular care must be taken when making the electric shock protection circuit:
yellow-green protection conductor of the power cable must be connected from one
side to the clamp marked
the power supply unit without correctly installed and technically functional electric
shock protection circuit is NOT ALLOWED!
This can lead to damage to the equipment and poses risk of electric shock.
5. Connect the conductors of the consumers to terminals '+' and '-' of the connection block on the
power supply unit board [11].
6. If necessary, connect the conductors from the equipment (alert central appliance, controller,
signalling units, etc.) to technical outputs:
- BS the output signalling the fault to the 230V/ AC
In the course of the normal operation of the powerpack, the BS technical output is disconnected from
the mass ('-'), while in the case of the 230 V AC power failure, it is shortened to the mass ('-') after the
time determined by the Z1, Z2 [5] switching pieces (Tab. 3)
- AW output signalling faults
The technical output AW during the normal operation of the power supply unit is shortened to the
mass ('-'), while in the case of the occurrence of any of the above-mentioned events, the output
becomes disconnected from the mass.
7. With the switching pieces Z3, Z4 [5] determine the time of disconnecting the battery in the case of
battery assisted operation when the voltage on the terminals drops below ~10V.
8. With CHARGE jumper , determine the battery charging current:
I
= ~0,45A – jumper CHARGE installed
ACC
I
= ~0,9A – jumper CHARGE removed
ACC
9. Switch on the power supply 230V AC and insert the network fuse protecting the primary circuit of
the transformer [15]. Check the optical signalling of the power supply unit operation
The output voltage of the unloaded power supply unit is ~13,8V DC.
During battery charging, the voltage may be anywhere between ~12V÷13,8V DC.
10 .Connect the battery in accordance with the indications [6] (colours).
11. By the means of the STOP [3] pushbutton, enable or disable the battery dynamic test (Tab.2)
Disabling the test will also disable signalling the faults to the battery on the AW output, but will not
disable the system protecting the battery from entire discharging.
12. Perform the power supply unit test: optical signalling [7] [8] (Tab.1), acoustic signalling [1],
technical outputs through:
- disconnecting the 230V AC power supply: optical and acoustic signalling - immediately,
technical output BS after the time determined by switching pieces Z1, Z2 (Tab.3) / 3. Indication of
operation of the power supply unit /
- disconnecting the battery: optical, acoustic signalling, technical output AW - following
performing the battery test (~ 10 min)
13. By the means of the STOP [3] pushbutton, enable or disable the battery dynamic test
Disabling the test will also disable signalling the fault to the battery on the output.
14. With ZB [2] pins, determine whether the acoustic signalling (Tab.2) is to be enabled (switching
piece installed) or disabled (switching piece removed).
15. Following installing and checking the correctness of operation of the power supply, the enclosure
may be closed.
3. Indication of operation of the power supply unit
The device is equipped with visual and sound indication of operation.
