1.1. Gener l description.
The power supply unit is intended for the feeding of alarm system equipments, which require 24V DC supply
voltage and current load I=2,5A. The design enables simple changing of the output voltage, within the range of 24V÷2 V
DC, using a potentiometer. The power supply unit is protected against short-circuit, overload and overvoltage.

2. Inst ll tion.
2.1 Requirements.
The power supply shall be mounted by the qualified installer having appropriate (required and necessary for a
given country) 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 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 h s to be connected to the corresponding connector of the
supply unit. Oper tion without proper grounding of the power supply is not llowed!
2.2. Inst ll tion procedure.
1. Prior to installation of the power supply unit, make sure that power leads have been disconnected from the
230VAC mains.
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 sh ll be performed with p rticul r c re, i.e. the yellow nd green
protection wire of the power c ble sh ll be connected from one side to the termin l m rked by the
symbol of in the c sing of the power-supply. Oper tion of the power-supply without the properly
m de nd fully oper tion l circuit of the shock protection is
UNACCEPTABLE!
It c n result in f ilure of devices nd electric shock.
4. Connect load/loads to proper output connectors of the power supply (positive end is marked as +V,
negative end as -V).
5. Upon the completion of tests and trial activation, close the housing, cabinet etc.

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

GENERAL WARRANTY CONDITIONS
1. Pulsar K. Bogusz Sp.j. (manufacturer) grants a two-year quality warranty for the equipment, starting from the date of purchase
placed on the purchase order.
2. Should such purchase order be missing when the claim is submitted, the three-year guarantee period is counted from the date
of the manufacturing of the device.
3. The warranty includes free-of-charge repairing or replacing with a functional equivalent (the selection is made by the
manufacturer) of the malfunctioning device, due to reasons attributable to the manufacturer, including manufacturing and material
defects, unless such defects have been reported beyond the warranty period (item 1 and 2).
4. The equipment subject to warranty is to be brought to the place where it was purchased, or directly to the main office of the
manufacturer.
5. The warranty applies to complete equipment, including the type of defect specified in writing, using a properly filled warranty
claim.
6. Should the claim be accepted, the manufacturer is obliged to render warranty repairs, as soon as possible, however not later
that within 14 days from the delivering of the equipment to the service centre of the manufacturer.
7. The repair period mentioned in item 6 may be prolonged, if there is no technical capability to carry out the repairs, and in the
case that the equipment has been accepted conditionally, due to the failing of the warranty terms by the claimant.
. All the services rendered by force of the warranty are carried out at the service centre of the manufacturer, exclusively.
9. The warranty does not cover the defects of the equipment, resulting from:
- reasons beyond the manufacturer's control,
- mechanical damage,
- improper storage and transport,
- use that violates the operation manual or equipment application,
- random events, including lightning discharges, failures of power networks, fire, flooding, high temperatures and chemical agents,
- improper installation and configuration (at variance with the rules set forth in the manual),
10. Each confirmation of structural modifications or repairs, carried out beyond the service centre of the manufacturer, or any
modification of serial numbers or warranty labels, results in the loss of the rights resulting from the warranty.
11. The liability of the manufacturer towards the buyer is limited to the value of the equipment, determined according to the
wholesale prices suggested by the manufacturer on the day of purchase.
12. The manufacturer shall not be responsible for the defects that resulted from the damaging, malfunctioning or inability to
operate the equipment, particularly, if such defects are the result of failing to abide by the recommendations and requirements
contained in the manual, or the use of the equipment.
