2. Installation.
2.1 Requirements.
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 AC 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°C to
+40°C. 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, 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=10A (P=138W max.)
, including
the maximum 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 Installation procedure.
1. Before installation is started, the voltage in the 230V power-supply circuit shall be isolated.
2. The power-supply shall be mounted in a selected location and connection cords shall be lead.
3. The power cables (230 VAC) 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 circuit of the shock protection shall be performed with a particular care, i.e. the yellow and
green protection wire of the power cable shall be connected from one side to the terminal
marked by the symbol of
in the casing of the power-supply. Operation of the power-supply
without the properly made and fully operational circuit of the shock protection is
UNACCEPTABLE! It can result in failure of devices and electric shock.
4. Connect the conductors of the loads to the +AUX-, +AUX1-, +AUX2-, +AUX3- terminals of the terminal box on
the power-supply unit.
