6. If necessary, connect the conductors from the equipment (alert central appliance, controller,
6. Switch on the power supply 230V AC and insert the network fuse protecting the primary circuit of
the transformer [8]. Check the optical signalling of the power supply unit operation.
The output voltage of the unloaded power supply unit is ~12,0 V/DC.
7. For installation with considerable voltage drops on resistance of the wires incoming to the
consumers, it is possible to adjust the voltage level with assembly potentiometer [5]
(~11,0V÷15,0V DC).
•
A - outputs A1, A2, A3
•
B - outputs B1, B2, B3
•
C - outputs C1, C2, C3
8. Following installing and checking the correctness of operation of the power supply, the enclosure
may be closed.
3. Indication of operation of the power supply unit
The device is equipped with visual indication of operation. Voltage presence across the outputs of the
power supply unit is indicated by LEDs lighting at the unit front panel Ax, Bx, Cx ;x:{1,2,3}..
A1, A2, A3
B1, B2, B3
C1, C2, C3
RED LED:
•
lit - power supply unit operated from 230 V/AC (~AC)
•
no lit - shortage of power supply 230 V/AC (~AC)
GREEN LEDs:
•
lit - voltage DC on output enabled
•
no lit - shortage of output voltage DC ( failure output )
