2. Installation
2.1. Requirements
The buffer PSU module is dedicated for installation by the qualified electrician, holding relevant permits and
licenses (applicable and required for the specific country) for connecting (interference with) the 230V/AC and low-voltage
systems. The unit should be mounted in the non-open premises, in accordance with the II-nd environmental class, with
the normal relative humidity (RH=90% maximum, without condensing) and temperature within the range -10°C to +40°C.
The should be operated in the position ensuring that the air may freely flow through ventilation openings in a
convectional way.
1. Output current 2,0A + 0,2A battery charging
2. Output current 2,0A + 0,5A battery charging
Total device c battery: 2,5A max.
As the PSU module is designed for constant operation, it is not equipped with supply isolator, the proper overload
protection in the supply circuit should be ensured. Also the user should be advised of the methods of disconnecting the
PSU module from the supply voltage (most frequently through the separation and indication of the relevant fuse in the
fuse box). The wiring system should be completed in accordance with the applicable standards and regulations.
