4.1 PAC-Seal Connection Instructions
A conduit seal is necessary for most equipment enclosures in hazardous areas. Consult
your local codes for full guidance.
It is
very important that knowledgeable personnel, familiar with national and local
codes, supervise hazardous area equipment installations.
The sealing compound generally used for PAC-seals is an inorganic, chemically setting,
magnesium oxide base material, which develops a slight expansion while hardening
into a porcelain-like body. Sealing Compound is supplied as a powder and need only
be mixed with water to apply. Approximately one ounce of sealing compound is
needed per cubic inch of space to be filled.
IMPORTANT
• The sealing compound powder has a shelf life of six months when stored in
unopened, tightly sealed containers in a dry location at 70 ° F.
•
Any equipment accidentally splashed with sealing compound should be
cleaned with soap and water before the sealing compound cures.
Equipment Required
• Four PAC-Seal fittings, 1” NPT or 0.75” NPT for the X-Purge (2 for conduit
connection at the enclosure or I/O casting, 2 for connection in the safe area), or
sealing conduits. The PAC Seal and conduit size selected will depend on the size
and number of conductors, which must be run to the unit. Check with NEC tables to
determine the conduit size necessary
• Conduit for electrical signals and for electrical power (separate runs), NEC and NFPA
approved for use in hazardous areas
• NEC and NFPA approved flexible conduit if needed for difficult installations
• Fittings as required for permanent conduit installation NEC and NFPA approved for
use in hazardous areas
•
Signal cables, power cables, and connectors as required to mate with the
equipment within the enclosure or cast aluminum box
• AC power switch for use in the safe area
IMPORTANT
ALWAYS follow NEC, NFPA, and local codes when installing conduit and PAC-seals
in hazardous areas!
