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

(Item 1) to its back cover (Item 4) Using HEX KEY No. 5. Hold the housing
(Item 1) during the removal of the screws. With the screws removed, pull the

the detector cover is now revealed.

entry, pull the wires through the detector cover (Item 4) and secure them firmly
to the cover using the cable-clamp (Item 2) attached to it. Use a 3/4"-14NPT
or M25x1.5 explosion-proof conduit /cable gland connection to assemble the
conduit / cable to the detector.
5 Connect the wires to the required terminals (Item 3) according to the wiring
diagram. See paragraph 6.7.

(Fig. 8 item 2).
The detector must be well grounded to Earth Ground for proper
operation.

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.
