2. Installation.
2.1 Requirements.
The buffer PSU shall be mounted by a qualified installer with appropriate permissions and qualifications for
230V/AC installations and low-voltage installations (required and necessary for a given country). The device shall
be mounted in confined spaces, according to the environment class II, with normal air humidity (RH=90% max.
without condensation) and the temperature from -10°C to +40°C. The PSU shall work in a vertical position that
guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
During normal operation, the total current drawn by the equipment may not exceed I = 1,0A.
Maximum battery charging current: 0,2A. Total device c battery: 1,5A max.
As the PSU is designed for a continuous operation and is not equipped with a power-switch, therefore an
appropriate overload protection shall be guaranteed in the power supply circuit. Moreover, the user shall be
informed about the method of unplugging (usually through assigning an appropriate fuse in the fuse-box). The
electrical system shall follow valid standards and regulations.
2.2 Installation procedure.
1. Before installation, cut off the voltage in the 230V power-supply circuit.
2. Mount the PSU in a selected location and connect the wires.
3. Connect the power cables (~230Vac) to L-N clips of the PSU. Connect the ground wire to the clip marked by the
earth symbol PE. Use a three-core cable (with a yellow and green PE protection wire) to make the connection.
Lead the cables to the appropriate clips through the bushing of the connection board.
The shock protection circuit shall be performed with a particular care, i.e. the yellow and
green wire coat of the power cable shall stick to one side of the terminal - marked with
‘
‘
symbol on the PSU enclosure. Operation of the PSU without the properly made and
fully operational shock protection circuit is UNACCEPTABLE! It can cause a device
failure or an electric shock.
4. Connect the receivers’ cables to the +AUX, -AUX connectors of the terminal block on the PSU board.
5. If necessary, connect the device conductors to the technical outputs:
- FAC; AC status indication (alarm panel, controller, indicator, LED, etc.)
Use the
T
AC
(J1,J2)
jumper to determine
the indication time lag.
- TAMPER; the indicator preventing the PSU from unwanted opening
6. Allowing of the battery parameters, determine the maximum charging current using the I
BAT
pins.
7. Using the P
BAT
pins, determine whether the function of disconnecting the discharged battery U<10V (+/-5%) is to
be on or off.
The battery protection is on
if the P
BAT
jumper is removed.
8. Activate the ~230V/AC supply (the AC red diode and AUX diode should be permanently illuminated)
9. Check the output voltage (the PSU voltage without load should amount to 13,6 V÷ 13,9 V, during battery
charging 11 V÷ 13,8 V). If the value of the voltage requires adjustment, it should be set by the V
ADJ
potentiometer,
monitoring the voltage at the AUX output of the PSU.
10. Connect the battery in accordance with the signs: +BAT red to ‘plus’, -BAT black to ‘minus’, (the LB diode light
should fade throughout the time of charging).
11. Once the tests and control operation have been completed, close the PSU.
