AMEVision Host Display to sensor
AMEVision Host Display to host computer (RS-485 communications)
All wiring conductor ratings should be for the minimum temperature
required for the equipment being connected to the analyzer, but not less
than 60 °C.
Use only the applicable ATEX-Certified cable glands to maintain the ATEX
rating for the AMEVision Display User Interface. If not using a conduit en-
try, leave the factory ATEX/NEMA-approved plugs intact. Never leave any
holes unplugged.
Follow all applicable electrical codes for your location.
Follow proper grounding, shielding and noise protection practices as de-
scribed in this section.
Use twisted-pair cable with an overall braided shield, or twisted-pair cable
in rigid metal conduit for all sensor and signal wiring.
For AC mains supply wiring, use 12 to 14 American Wire Gauge (AWG)
(3.3 mm2 and 2.1 mm2).
For all signal wiring, use 18 to 24 AWG (0.82 mm2 to 0.33 mm2).
For sensor connections, Figure 1-2 shows the recommended sensor cable
types for various WDG-style sensors.
Use the conduit entry point closest to the connections you are making.
Do not add any additional conduit entry holes.
You may use 1" conduit with a 3/4" adapter at the entry to the AMEVision
Host Display for signal and sensor wiring.
