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 be mounted in a close casing (a cubicle, a terminal device) and in order to fulfill LVD and
EMC requirements the rules for power-supply, encasing and shielding shall be observed according to application.
Due to the power supply design, the PE wire has to be connected to the corresponding connector of the
supply unit. Operation without proper grounding of the power supply is not allowed!
Prepare the power supply loading balance before installation. Under normal operation, the total current
drawn by the device may not exceed I = 1 A. Maximum battery charging current: 0,5 A. Total device c
battery: 1,5 A max.
2.2. Installation procedure.
1. Before beginning installation, ensure that the power in the 230V AC power supply circuit is disconnected.
2. Install the unit in the previously selected place.
3. Connect the 230VAC power leads. Connect the PE cable (yellow-green) to an appropriate terminal on the
power supply unit (marked with
).
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 load/loads to proper output connectors of the power supply (positive end is marked as +V,
negative as -V).
5. Connect battery to the unit according marks (colors).
6. After the completion of tests and trial activation, close the housing, cabinet etc.
