2. Installation.
2.1 Requirements.
The buffer PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for 230 V interference and low-voltage installations. The unit should be mounted in confined
spaces, in accordance with the I environmental class, with normal relative humidity (RH=90% maximum, without
condensing) and temperature from -10°C do +40°C. The PSU shall work in a vertical position that guarantees sufficient
convectional air-flow through ventilating holes of the enclosure.
The unit should be mounted in a metal enclosure (cabinet) in a vertical position so as to ensure free, convection
air flow through the vents. In order to meet the EU requirements, follow the guidelines on: power supply, enclosures and
shielding: - according to application.
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.
CAUTION!
Before installation, make sure that the voltage in the 230 V power-supply circuit is cut off.
To switch off power 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 and connect the wires.
2. Connect the power cables (~230 V) to AC 230 V clips of the transformer. Connect the ground wire to the
clip marked by the earth symbol
. Use a three-core cable (with a yellow and green protection wire) to
make the connection. Lead the cables to the appropriate clips of the subplate through the insulating
bushing.
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 - in the PSU
enclosure. Operation of the PSU without a properly made and fully operational shock
protection circuit is UNACCEPTABLE! It can cause a device failure or an electric shock.
3. If needed, connect the device cables to the technical outputs:
- EPS; technical output indicating AC power failure
- APS; technical output indicating battery failure
4. Connect equipment to the appropriate output terminals of power supply (positive connector +V, negative
connector -V)
5. Use the I
BAT
jumper to set the maximum battery charging current, taking into account the battery parameters and
required charging time.
