To reduce the risk of fire or explosion, do not install the beacon
in a hazardous location if the operating temperature exceeds the
ignition temperature of hazardous atmosphere.
Before proceeding, use Table 4 above as a guide and determine
that the unit’s operating temperature DOES NOT exceed the
hazardous atmosphere’s ignition temperature.
For marine applications, all wiring including supply wire must be
stranded wire and meet the USCG (CFR46) Sections (110-113).
NOTE:
In high-humidity environments when units are mounted
dome down, condensation may occur in the conduit system. Use
properly rated conduit seals/drains to prevent moisture from
entering the fixture.
