4.2. Installation procedure.
CAUTION!
Before installation, cut off the voltage in the 230 V power-supply circuit.
To switch power off, use an external switch, in which the distance between the contacts of
all poles in the disconnection state is not less than 3mm.
It is required to install an installation switch with a nominal current of 6 A in the power supply circuits
outside the power supply unit.
1. Mount the PSU in a selected location with use of special metal expansion bolts. Do not use PVC
dowels.
2. Connect the power cables ~230 V to the L-N terminals of the PSU. The cable length inside the housing
should not exceed 10 cm. Connect the ground wire to the terminal marked with grounding symbol in
enclosure. Use a three-core cable (with a yellow and green protection wire) to make the connection.
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.
3. Connect the receivers’ cables to the AUX1 and AUX2 output terminals on the PSU board.
4. If needed, connect the cables from the devices to the technical inputs and outputs:
- ALARM; technical output of collective failure of the PSU
- EPS; technical output of AC power loss indication
- EXTi; input of collective failure
5. Install the batteries in a designated area of the enclosure (see Fig. 3).
Connect the batteries with the PSU paying special attention to the correct
polarity. Batteries must be connected in series using the special cable
(included). Attach the temperature sensor to any of the batteries with
mounting tape (included). Place the temperature sensor between the
batteries.
6. Switch on the ~230 V supply. The corresponding LEDs on the power supply PCB should be ON: 230 V
green and AUX1, AUX2.
7. Check the current consumption of the receivers, taking into account the battery charging current, so as
not to exceed the total current efficiency of the PSU (see section 3.1).
8. Once the tests are completed, close the enclosure.
