6.6 Wiring (Refer to Fig. 12)

1 Disconnect power.

2 Remove the four (4) protective set-screws from detector front. (Fig. 8 Item 1)

3 Release the four (4) socket-head screws that secure the detector housing

(Item 1) to its back cover (Item 5) Using HEX KEY No. 5. Hold the housing

(Item 1) during the removal of the screws. With the screws removed, pull the

detector housing (Item 1) from its cover (Item 5). The cover remains attached

to the detector mount, the housing slides under the cover and remains

attached to it by a securing cable (Item 2). The Terminal Board inside the

detector cover is now revealed.

4 Remove the protective plug mounted on the detector conduit inlet, pull the

wires through the detector cover (Item 5) and secure them firmly to the cover

using the cable-clamp (Item 3) attached to it. Use a 3/4"-14NPT or M25x1.5

explosion-proof conduit connection to assemble the conduit to the detector.

5 Connect the wires to the required terminals (Item 4) according to the wiring

diagram. See paragraph 6.7 and figures no. 10 and no. 11.

6 Connect the grounding wire to the ground screw outside the detector cover

(Fig. 8 item 2).

The detector must be well grounded to Earth Ground for proper

operation.

7 Verify the wiring. Improper wiring may damage the detector.

8 Check the wires for secure mechanical connection and press them neatly

against the terminal board to prevent them from interfering while closing the

detectors’ housing.
