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.
MSA 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.
