Chart 1. Acceptable output current from the PSU depending on ambient temperature.
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.
Before installation, prepare a PSU load balance:
1. Output current 9x0,5A + 1A battery charge
2. Output current 9x0,5A + 2A battery charge
Total device c battery: 7A 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 (PSU module connector). 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 insulating 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.
