I/O Manual
6. Add extra wire length of 1.25" (31.75 mm) past
top of opening in explosion-proof/ameproof box
to pluggable terminal block. (Allows connector
to be moved out of the way when changing
electronics. Prevents repouring seals.)
7. Conduit seal on I.S. wiring side must be within
18" (457.2 mm) of the explosion-proof/ameproof
box.
8. Wire should be copper only, rated 90 °C
minimum.
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
2
) to 26 AWG (0.081 mm
2
)
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).
6. Wire should be copper only, rated 90 °C
minimum.
7. The minimum wire strand in a stranded wire
should have a diameter of 0.1 mm or greater.
WARNING – The 6000-ISB I.S. termination board
and 6000-TEMP are not certied to operate in
dust-hazardous locations. The 6000-DPE is a
dust-proof enclosure designed only to house
either or both the I.S. termination board and 6000
temperature hub. No other devices are allowed
in the enclosure. This does not apply to the 6000
control unit with housing, a complete unit.
