8.2 Purged Unit Instrument RJ-45 Connection
The Purged Enclosure uses different AC Power
and communication entrances.
The instrument air is routed to the entrance on
the filter, as shown.
AC (“mains”) power is provided to the lower
entrance on the box where shown in this
photo. This shows the temporary AC power
cord. A permanent installation must use
dedicated wiring, in accordance with local
codes.
The RJ-45 fiber optic communication lines enter
the enclosure. From here, the cables go to the
fiber optic modem located inside the
instrument.
The purge enclosure uses a 100BaseTX-FX
Media Converter for safety and clean
communications in a factory environment.
A 30-meter fiber optic pair is supplied. Longer
lengths are available by special order. Maximum
cable distance is 2 kilometers. This is a full-
duplex system.
The fibers must be fed into the enclosure using
a proper fitting, as shown at right.
The modem is shown with the correct fitting for
purge systems. The connections ends are
shown, with protective covers in place. The
covers must be removed to attach the cables.
