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 the battery to the B +, B- terminals. Determine the charging current using jumpers according to
the table below.
6. After the completion of tests and trial activation, close the housing, cabinet etc.
