Note
Twisted pair wiring is required for RS-485 bus wiring. Wiring runs
under 1000 ft. (305 m) should be AWG 22 or larger. Wiring runs from
1000 to 4000 ft. (305 to 1219 m) should be AWG 20 or larger. Wiring
should not exceed AWG 16.
NOTICE
When the enclosed threaded plug is utilized in the conduit opening, it
must be installed with a minimum engagement of five threads in order
to comply with explosion-proof requirements. Refer to the Rosemount
4088 MultiVariable Transmitter Reference Manual for more
information.
6. Reinstall the housing cover and tighten so the cover is fully seated with
metal to metal contact between the housing and cover in order to
meet explosion-proof requirements.
Note
Installation of the transient protection terminal block does not provide
transient protection unless the transmitter housing is properly
grounded.
