Connect the wires to the required terminals on the Terminal Board according to the
wiring diagram (Figure 7) and Table 17.
6
Connect the grounding (earth) wire to the ground (earth) screw outside the detector
(Earth Terminal). The detector must be well grounded to earth ground.
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 to prevent them from interfering while closing the back cover (Figure 7).

VERIFYING THE DETECTOR WIRING
The detector has five output wiring options within the EExde integral terminal section of
the enclosure. There are 12 terminals labeled 1-12.
For more information on the wiring options, see
Wiring Instructions
on page 43.
For mA wiring options see Figure 10, Figure 11, Figure 12, and Figure 13.
For relay connection options see Figure 9.
Table 17 describes the function of each terminal for all the wiring options.
