2.2. Installation procedure.
1. Mount the enclosure (cabinet, etc.) and lead cables through cable glands.
2. Mount the DC/DC converter with adhesive tape or mounting screws.
3. Supply DC voltage to the + IN, -IN terminals with correct polarization.
4. Connect the re
ceivers’ cables to the +AUX, -AUX connectors of the terminal block on the module’s board.
5. Switch on the DC voltage (the red IN LED should be permanently illuminated, the AUX green LED should be permanently
illuminated).
6. Once the tests and operation control are performed, close the enclosure, cabinet, etc.
3. Converter 's module operation indication.
3.1. Technical output.
The converter is equipped with two diodes indicating operation status: IN, AUX.
IN- red LED
: during normal status (DC power supply) it is lit continuously. No DC supply is indicated by switching off the IN
LED.
AUX
-
green LED
: indicates DC supply status at the module’s output. During normal status, it is lit continuously, in case of
short circuit or overload the AUX led is off.
4. Maintenance and operation.
4.1. Overload or short circuit of the converter output.
The AUX output is protected with the PTC polymer fuse. If the load current exceeds Imax (110% ÷ 150% @ 25ºC of the
converter capacity), the output voltage will be automatically disconnected, which will be signaled by switching off the green AUX LED.
Voltage restoration requires disconnecting the output load for approx. 1 min.
In case of power supply overload, the output voltage is automatically disconnected, which is indicated by turning off the
corresponding LED. The voltage is automatically restored once the fault (overload) is cleared.
4.2. Activation of the overload protection of the power supply unit.
In case of the activation of the overload protection, the output voltage is automatically disconnected. Restart is possible after
disconnecting the converter from the power source for at least 20 seconds.
5. Maintenance.
All maintenance procedures can be performed after disconnecting the converter from the power network. The converter does
not require any specific maintenance; however, its interior should be cleaned with compressed air if used in dusty conditions.
