combustibles card, you may want to connect the required intercon-
necting wires when you first install your analyzer, especially if run-

ning the wires over long distances through conduit.

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
fittings to maintain the NEMA rating for the Series 2000 controller
or sensor enclosure. If not using 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.
Use twisted-pair cable with an overall braided shield, or twisted-pair
cable in rigid metal conduit for all sensor and signal wiring.
