NTRODUCTION
PWR2D/4D is power supply unit with rated output voltage increased from 12.0Vdc to 13.8Vdc by means of
user available potentiometer. PWR2D/4D is dedicated to installation in ACMAX system, particularly to supply
EXP2D/4D. The PWR is dedicated to installation inside enclosure and can be installed only by qualified
technician with all necessary certificates concerning connection and maintenance of 230Vac and low voltage
networks. BOX-IP-15/16 (AC-MAX) metal enclosure are factory adapted to installation of PWR2D/4D.

NSTALLATION
1. The PWR must be installed inside enclosure in order to properly protect it against unauthorized persons.
2. All installation and maintenance works must be done with 230Vac power supply disconnected.
3. Cable F which is connected to electric shock protection circuit must be connected to PWR's terminal
with symbol.
4. Power supply 230Vac must be connected to L and N terminals of the PWR.
5. PWR's terminals V+ and V- must be connected to supplied device using included wires which prevent
significant voltage drop between PWR and the device. Low drop of voltage is particularly essential when
the device is equipped with battery as lowered voltage might prevent full battery charging.
6. Starting, configuration and adjustments must be done in accordance with system procedures after
connection of 230Vac power supply.
7. Do not alter the potentiometer which is factory adjusted to 13.8Vdc output voltage.
8. Close the enclosure with mounted PWR when installation and starting works are finished.
The installation can be done only by qualified person with all necessary
certificates concerning connection and maintenance of 230Vac and low
Earthing system must be executed carefully, properly and effectively.
