Ø
To connect the detector to the electrical cables
15
Disconnect the power.
16
Remove the back cover of the detector by removing four (4) socket head-screws in the
cover bolts. The terminal chamber is now revealed.
17
Remove the protective plug mounted on the Detector Conduit/Cable entry; pull the
wires through the Detector Inlet.
18
Use a ¾" – 14 NPT explosion-proof conduit connection or M25x1.5 flameproof gland
to assemble the cable / conduit to the detector.

19
Connect the wires to the required terminals on the Terminal Board according to the
wiring diagram (Figure 7) and Table 17.
20
Connect the grounding (earth) wire to the ground (earth) screw outside the detector
(Earth Terminal). The detector must be well grounded to earth ground.
21
Verify the wiring. Improper wiring may damage the detector.
22
Check the wires for secure mechanical connection and press them neatly against the
terminal to prevent them from interfering while closing the back cover (Figure 7).
