Installation in Hazardous Locations
For installation in hazardous locations, the RMA 3000 must be configured and installed as detailed in the
appropriate Honeywell-certified engineering drawing(s), which conform to practices specified by various
approval agencies. Installation requirements vary somewhat among approval agencies, but all are based on
the fact that each meter is housed in a sealed fireproof/explosion-proof housing.
Wiring-Port Seals at Remote Housing
When used in hazardous environments, the remote housing must be configured as a flameproof/explosion-
proof housing, in which all points of entrance and exit for wiring are protected and sealed via rigid metal
conduit or suitable cable gland fittings.
Examples of metal conduit fittings are shown in Figure 3, and an example of a sealed cable gland is shown
in Figure 4.
