General Wiring and Conduit Requirements
This section describes general wiring and conduit requirements.
• Analyzer wiring conductors must be rated at a minimum of 80 °C. All other
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 NEMA-approved conduit fittings or cable fittings
to maintain the NEMA rating for the analyzer enclosure or WDG-V. If not us-
ing a conduit entry, leave the factory 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
described in this section.
• For all analyzer and signal wiring use twisted-pair cable, 18 to 24 AWG
(American Wire Gauge) (0.82 mm
2
to 0.33 mm
2
), with an overall braided
shield, or twisted-pair cable in rigid metal conduit.
• For AC mains supply wiring, use between 12 and 14 AWG or equivalent
metric between 3.3 mm
2
and 2.1 mm
2
.
• Use the conduit entry point closest to the connections you are making.
Do not add any additional conduit entry holes!
