Wiring
This wiring section shows you how to make the following connections:
• AC mains supply wiring to control unit
• AC mains supply wiring to sensor
• AMEVision Host Display to sensor
• AMEVision Host Display to host computer (RS-485 communications)
In addition, this wiring section provides mandatory EMC grounding, shielding,
and noise protection requirements.
General Wiring and Conduit Requirements
This section describes general wiring and conduit requirements.
• 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.
