2. Installation.
The buffer power pack is dedicated for assembly by the qualified assembly man, holding relevant
certificates (as required and necessary for the specific country), permissions and authorizations for making
connections in 230 V AC systems and LV systems. The equipment should be assembled in non-open-space
rooms, in accordance with environment class II, with standard air relative humidity (RH – 90% maximum, without
condensation) and the temperature within the range from - 10°C to +40°C. The power pack should be operated in
the vertical position such that the free air convection is ensured through the ventilation openings of the enclosure.
Prior to entering for installation, the balance of power pack loads should be drawn up. During the normal
operation the sum of currents consumed by the consumers may not exceed 3A, with the incorporation of the
battery charging current.
As the power pack is designed for the constant operation, the circuit breaker is not included and this is
why the proper and appropriate shock protection in the power supply circuit must be ensured. Also the users
should be informed about the method of disconnecting the power pack from the power supply voltage (most
frequently through the separation and designation of the relevant fuse in the fuse box). The wiring system should
be completed in accordance with the applicable norms, standards and regulations.
Caution: Prior to entering for installation make sure that the voltage in the 230 V power supply circuit
is disconnected.
1. Assemble the power pack in any place and connect the connection leads.
2. Remove the power grid fuse protecting the transformer primary circuit.
3. Connect the 230 V power supply conductors to the 230 V AC transformer terminals [8]. The earthing
conductor should be connected to the terminal designated with the earthing symbol [10]. The connection
should be made by means of the three-wire cable (with yellow-green PE protective conductor). The power
supply conductors should be evacuated to the relevant terminals of the connection board, through the
insulation pass.
