Completing the Installation
For the following,
1. Unscrew the M5 Socket Head Cap screws from the base. Remove the detector from the
base.
2. Detach NPT conduit bushing from base.
3. Install the base on a suitable work platform and secure using the 4 mounting screws,
washers, nuts, and rubber grommets.
4. Run the power, control, and ground wires from the conduit into the conduit bushing and
connect to the wiring terminals in the base. Follow Figure 6‐2, Arrangement and Functions
of Mounting Connection Terminals, for details.
5. Tighten the conduit bushing to 4‐1/2 +‐ 1 turns of engagement. Seal the conduit entry
with an approved hazardous location conduit sealant.
6. Run the earth ground wire to the external ground stud on the base.
7. After completing all wiring, refer to Table 6‐1 to verify the functionality of the front cover
LEDs.
8. Inspect base and re‐apply a thin film of anti‐seize compound if required; re‐install the
detector on the base and evenly tighten the M5 screws to 40 in‐lbs.
9. Upon completing the installation, check the resistance of the earth ground lug to ground
which should not exceed 1 ohm.
10. Arrange the power‐supply system so that the power‐supply voltage across the device
terminals ranges from 18 to 32 V (taking into account the IPES‐IR3 consumption).
