2.3.1. AC Power
When wiring the Gas Monitor to a permanent AC source, the AC source circuit breaker and / or switch
must be IEC approved. The circuit breaker and / or switch must be near the unit and marked as the
disconnect device. The minimum current rating must be 10A. Minimum wire size for line power
conductors is 18 AWG. Use only U.L. listed conduit and hubs that are the same or better environmental
rating as the enclosure.
2.3.1.1.
Unlatch and open the Gas Monitor cover.
2.3.1.2.
Confirm that the AC power is not energized, and thread the wires through the top
Rigid / IMC grounding hub. A cable that totally encases these conductors is
recommended. Make certain to tighten the Rigid / IMC grounding hub sufficiently to
ensure a moisture resistant seal to the cable conduit.
2.3.1.3.
Make certain the Rigid / IMC grounding hub is secured tightly to the Gas Monitor
enclosure.
2.3.1.4.
Make certain the wires are properly secured to the AC Terminal Block. See the
below figure for location.
NOTE: AC (Earth) ground must terminate on TB1 ground terminal to prevent electric shock
hazard.
2.3.2. DC Power
2.3.2.1.
Unlatch and open the Gas Monitor cover.
2.3.2.2.
Confirm that the DC power is not energized, and thread the wires through the bottom
Rigid / IMC grounding hub. A cable that totally encases these conductors is
recommended. Make certain you tighten the Rigid / IMC grounding hub sufficiently to
ensure a moisture resistant seal to the cable conduit.
2.3.2.3.
Make certain the Rigid / IMC is secured tightly to the Gas Monitor enclosure.
