2. Installation.
2.1. Requirements.
The power suppl shall be mounted b the qualified installer having appropriate (required and necessar for a
given countr ) permissions and qualifications for connecting (operating) low-voltage installations. The unit shall be
mounted in closed rooms, according to the environment class II, of the normal air humidit (RH=90% max. without
condensation) and the temperature within the range from -10°C to +40°C.
The power suppl 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-suppl , 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 o the
supply unit. Operation without proper grounding o the power supply is not allowed!
2.2. Installation procedure.
1. Prior to installation of the power suppl unit, make sure that power leads have been disconnected from the
230VAC mains.
2. Install the unit in the previousl selected place.
3. Connect the 230VAC power leads. Connect the PE cable ( ellow-green) to an appropriate terminal on the
power suppl unit (marked with ).
The circuit o the shock protection shall be per ormed with a particular care, i.e. the yellow and green
protection wire o the power cable shall be connected rom one side to the terminal marked by the
symbol o in the casing o the power-supply. Operation o the power-supply without the properly
made and ully operational circuit o the shock protection is
UNACCEPTABLE!
It can result in ailure o devices and electric shock.
4. Connect load/loads to proper output connectors of the power suppl (positive end is marked as +V,
negative end as -V).
5. Upon the completion of tests and trial activation, close the housing, cabinet etc.

3. Maintenance.
All maintenance procedures can be performed after the disconnection of the power suppl from the electrical grid.
The power suppl does not require an special maintenance procedures, but in the case of significant dust accumulation,
dusting using compressed air is recommended.

placed on the purchase order.
2. Should such purchase order be missing when the claim is submitted, the three- ear guarantee period is counted from the date
of the manufacturing of the device.
3. The warrant includes free-of-charge repairing or replacing with a functional equivalent (the selection is made b the
manufacturer) of the malfunctioning device, due to reasons attributable to the manufacturer, including manufacturing and material
defects, unless such defects have been reported be ond the warrant period (item 1 and 2).
4. The equipment subject to warrant is to be brought to the place where it was purchased, or directl to the main office of the
manufacturer.
5. The warrant applies to complete equipment, including the t pe of defect specified in writing, using a properl filled warrant
claim.
6. Should the claim be accepted, the manufacturer is obliged to render warrant repairs, as soon as possible, however not later
