Harsh Enclosure Cable Openings
The standard glands and plugs provided with the IND780 Harsh Enclosure are
NOT ATEX-certified for increased safety and therefore not suitable for installation in
a Zone 2/22 environment. IND780 terminals supplied in Europe have ATEX plugs
in their openings, and are shipped with a kit of ATEX glands. For IND780 terminals
supplied elsewhere, METTLER TOLEDO supplies an optional ATEX Glands kit
(#64063383) that has enough ATEX-certified glands and plugs for all connections
to the harsh enclosure. Figure 2-18 and Table 2-2 show the uses and cable size
limits of the various openings in the back of the harsh enclosure, installed using
cable glands from KOP #64063383. The pattern code is included for ease of
reference. It is important to use cables that are within the cable size limits specified
for the glands to ensure proper sealing of the enclosure.
