Wrapping should be done as close to the enclosure as possible.
2.9.2.2. Option Board Cabling
In order to prevent electromagnetic interference when installing option boards (especially Analog
Load Cell boards) in the terminal, twist the loose wires together, as shown in Figure 2-18, before
attaching the green connector to the board.

Harsh Enclosure Cable Glands and Cable Assignments

2.9.3.1. Harsh Enclosure Cable Openings
ORDER TERMINAL WITH PART NUMBER ENDING IN 96 FOR DIVISION 2, 97 FOR ATEX. ALL OTHER IND780
TERMINALS ARE NOT SUITABLE FOR USE IN HAZARDOUS AREAS
FOR TERMINALS MARKED FOR USE IN DIVISION 2 AREAS, THE ONLY SUITABLE CONNECTIONS VIA GLANDS ARE:
PDX, ANALOG LOAD CELL AND FLOW METER.
FOR TERMINALS MARKED ATEX/IECEX, ANY CONNECTION IS ALLOWED USING CORD GRIPS MARKED Ex 'e.'
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 2-19 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.
