2. Installat on.
2.1 Requ rements.
The buffer power-supply shall be mounted by the qualified installer having appropriate (required and
necessary for a given country) permissions and qualifications for connecting (operating) 230V/A installations and
low-voltage installations. The device shall be mounted in closed rooms, according to the environment class II, of
the normal air humidity (RH=90% max. without condensation) and the temperature within the range from -10° to
+40° . The power-supply shall operate in a vertical position so that free and convectional air flow through
ventilating holes of the casing is guaranteed.
Before installation is started, the balance of the power-supply load shall be performed. During the normal
operation, the sum of currents collected by receivers shall not exceed I=3,5A (P=49W) including the battery
charging current Ibat.
As the power-supply is designed for a continuous operation and is not equipped with a power-switch,
therefore an appropriate overload protection in the power supply circuit shall be guaranteed. Moreover, the user
shall be informed about the method of isolation of the power supply from the power voltage (usually through
assignment and marking of an appropriate fuse in the fuse-box). The electrical system shall be made in
accordance with valid standards and regulations.
2.2 Installat on procedure.
1. Before nstallat on s started, the voltage n the 230V power-supply c rcu t shall be solated.
2. The power-supply shall be mounted in a selected location and connection cords shall be lead.
3. The power cables (~230Vac) shall be connected to L-N terminals of the power supply. The earth conductor shall
be connected to the terminal marked by the earth symbol . The connection shall be made by means of a three-
core cable (with a yellow and green PE protection wire). The power cables shall be lead to appropriate terminals of
the connection board through bushing.
The c rcu t of the shock protect on shall be performed w th a part cular care, .e. the yellow and
green protect on w re of the power cable shall be connected from one s de to the term nal marked
by the symbol of n the cas ng of the power-supply. Operat on of the power-supply w thout the
properly made and fully operat onal c rcu t of the shock protect on s
UNACCEPTABLE!
It can result n fa lure of dev ces and electr c shock.
4. onnect the conductors of consumers to the +AU, -AUX terminals of the terminal box on the power-supply unit.
5. If necessary, connect the conductors from the equipment to the technical outputs:
- BS A status indication (alarm panel, controller, signaling unit, LED diode, etc.)
- AW technical output of operation status of the power supply
