Interface to Auxiliary Equipment
The interface cabling, to either flue gas analyzers or systems
connected to the 4-20mA outputs, must be overall braid
screened 2-core PVC insulated 24
AWG
– 7/32
AWG
(300V
80°C), for all signals. Wiring must comply with all
applicable codes, ordinances and regulations and where
required must comply with NEC Class 1 (Line Voltage)
wiring. Terminate the screen
at the unit only
using the
cable clamp provided.
If this cable is run in conduit with other cables its
specification may need to be increased to ensure its voltage
rating exceeds the maximum voltage carried by any other
cable in the same conduit.
