The DRA-DCC-8 is designed for standard DIN rail mounting.
Place the unit on the upper part of the mounting rail with the fastening tab facing
down. Using a suitable flat screwdriver loosen the tab slightly and attach the unit
to the rail. Once the tab is loosened, ensure that the unit is fastened securely in
place.
2. REPLACING FUSES
In order to replace a blown fuse, the unit has to be disassembled, as follows:
a. Take off both terminal strips by removing the four screws at the edges.
Note: This does not require disconnecting the cables connected to the strips.
Remove the front panel using a suitable flat screwdriver. Press down gently on
the plastic springloaded tabs located in the slots either side of the unit.
c. Disconnect the flat connector which couples the LED circuit on the front panel.
d. Replace the blown fuse.
WARNING: Never install a fuse rated more than 800mA
3. ASSEMBLY
The DRA-DCC-8 unit includes
two printed circuit cards
designated as P.N 7041 and

circuit cards should occupy
the slots in the enclosure
according to fig 1.
