Det-Tronics HD - PROTECTION AGAINST MOISTURE DAMAGE

7. 1 95-86663
PROTECTION AGAINST MOISTURE DAMAGE
It is important to take proper precautions during
installation to ensure that moisture will not come in
contact with the electrical connections or components
of the system. The integrity of the system regarding
moisture protection must be maintained for proper
operation and is the responsibility of the installer.
NOTE
NEMA 4 / IP66 / IP67 rating requires the use of IP
washers / IP glands (M25) .
If conduit is used, we recommend installing drains,
according to local codes, at water collection points
to automatically drain accumulated moisture. It is also
recommended to install at least one breather, according
to local codes, at upper locations to provide ventilation
and allow water vapor to escape.
Conduit raceways should be inclined so that water will
flow to low points for drainage and will not collect inside
enclosures or on conduit seals. If this is not possible, install
conduit drains above the seals to prevent the collection
of water or install a drain loop below the detector with a
conduit drain at the lowest point of the loop.
Conduit seals are not required for compliance with
explosion-proof installation requirements, but are highly
recommended to prevent water ingress in outdoor
applications. Units with M25 thread must use an IP66
washer to prevent water ingress.
NOTE
For optimum performance and maximum service
life, care should be taken to protect the Model HD
from corrosive contaminants in the atmosphere.
