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 PSU module should be operated in the position ensuring that the air may
freely flow through ventilation openings in a convectional way.
Prior to entering for the installation, the balance of load should be drawn up. Pending the normal
operation, the sum of currents consumed by the consumers may not exceed
I=2,5A
with the inclusion of the
battery charging current
Ibat.
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.
The unit should be installed in the metallic enclosure (cabinet, equipment) equipped with the DIN TH35 rail
(width 35 mm) and, in order to meet the requirements of EU, the following rules should be observed: supply,
development, shielding - accordingly to the application.
The module requires for proper operation Voltage in range 16-22V AC with galvanic separation (transformer).
It is needed to compare power of the transformer with the Diagram.1. (S=f(I).
