Conduit Sealing
Each conduit run from a hazardous to a non-hazardous location should be sealed so that
gas or flames cannot pass from one electrical installation to another through the conduit
system. A conduit seal must also be installed within 18 inches of the Source and Receiver
enclosure if installed in a Division 1 location. A conduit seal may not be required if installed
in a Division 2 location.
General Monitors requires the use of a drain loop or conduit seal in the conduit to prevent
moisture from entering the unit housing. For installation in a Division 2 location using
Division 2 wiring methods, a drain loop or conduit seal may not be required. Consult
Article 501 of the NEC for details.
WARNING:
The conduit entries should be sealed per the NEC 501.15 or Canadian
Electrical Code Handbook (Part 1, Section 18-154) for Division 1
installations.
WARNING:
Unused cable entry holes must be sealed with an approved explosion-proof
stopping plug.
CAUTION:
Acetic acid will damage metal components, hardware, and other
components. If damage results from the use of a sealant that outgases
acetic acid such as a room temperature vulcanizing sealant (RTV), the two-
year warranty will be void.
CAUTION:
Consult the manufacturer for dimensional information on the flameproof
joints for repair.
