2.5 Electrical Installation
The sensor assembly wiring should be installed in accordance with local electrical codes. Proper electrical
installation of the gas sensor is critical for conformance to electrical codes and to avoid damage due to water
leakage.
If a conduit run exists, a drain should be incorporated. The drain allows condensation inside the conduit run to
drain safely away from the sensor assembly. Electrical seals act as a secondary seal to prevent water from
entering the wiring enclosure. However, electrical seals are not designed to provide an absolute watertight seal,
especially when used in the vertical orientation. The electrical seal fitting is required to meet the National
Electrical Code per NEC Article 500-3d (or Canadian Electrical Code Handbook Part 1 Section 18-154).
Requirements for locations of electrical seals are covered under NEC Article 501-5.
NOTE
A conduit seal is required to be located within 18" of the J-Box and sensor assembly.
Crouse Hinds type EYS2, EYD2 or equivalent are suitable for this purpose.
NOTE Water damage from water leaking into the enclosure is not covered by the Detcon warranty.
NOTE
Unused ports should be blocked with suitable
