either crimped to a single pin or grouped in an
external junction box with one wire going into the
terminal.
5. The wires must have a minimum insulation
thickness of 0.01" (0.25 mm).

6. Add extra wire length of 1.25" (31.75 mm) past
top of opening in explosion-proof/flameproof box
to pluggable terminal block. (Allows connector
to be moved out of the way when changing
electronics. Prevents repouring seals.)

minimum.
Attention
9. The minimum wire strand in a stranded wire
should have a diameter of 0.1 mm or greater.
For wires going to the I.S. interface board in the main
housing or to the DIN-rail-mount I.S. board:
1. The wire strip length is to be between 0.16" and
0.24" (4 mm and 6 mm).
2. The terminal blocks are rated for a wire size of
16 AWG (1.31 mm
3. The only terminals that might have multiple
connections are the shield connections.
These must be crimped to a single pin before
connection to the board.
4. If cables are used (recommended for
connections to the vents and UIC), it is
recommended that the cables be shielded.
5. The wires must have a minimum insulation
thickness of 0.01" (0.25 mm).
