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 II-nd 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.
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 min. 3 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. Connect the receivers’ cables to the +AUX, -AUX connectors of the terminal block on the PSU board.
4. If needed, connect the device cables to the technical outputs:
- EPS; technical output indicating AC power failure
- APS; technical output indicating battery failur
- optional installation of the AWZ639 relay module changing technical outputs of the OC type to relay type
(page. 10, section. 3.3)
5. Use the I
BAT
jumper to set the maximum battery charging current, taking into account the battery parameters and
required charging time.
6. Mount the battery in the battery compartment of the enclosure (Fig. 3). Connect the batteries with the PSU
paying special attention to the correct polarity and type of connections (Fig.4):
