2. Installation.
The power supply is dedicated for assembly by the qualified personnel, holding relevant certificates (as required
and necessary for the specific country), permissions and authorizations for making connections in 230 VAC 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 1,1A, with the incorporation of the battery charging current
Iacc = 0,1A
.
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 power supply is disconnected from 230V AC
mains.
1. Install the power supply and connect the connection leads.
2.
Remove the AC fuse F2 (refer to fig. 3 – element no. 9) 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 run as far as the relevant terminals of the connection board, through the insulation pass.
Caution: Pay special attention when completing the shock protection circuit: the yellow-green PE protective
conductor of the power supply cable must be connected from one side to the terminal designated
in the
power pack enclosure. The operation of the power pack without the shock protection circuit properly
completed and technically operable IS NOT ADMISSIBLE!
The operation without such circuit threatens with damage to the equipment or electric shock.
