General Wiring and Conduit Requirements
This section describes general wiring and conduit requirements.
• Sensor wiring conductors must be rated at a minimum of 80 °C. All
other wiring conductor ratings should be for the minimum tempera-
ture 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 fit-
tings to maintain the NEMA rating for the sensor enclosure or WDG-V.
If not using a conduit entry, leave the factory NEMA-approved plugs
intact. Never leave any holes unplugged.
