Termination Base Color Coding and Markings
Field wiring attaches to the terminal strips located behind the
front access door on a termination base (Fig. 7-1). To simplify
installation, field wiring terminals are clearly marked to iden-
tify positive (+) and negative (–) polarity; and three-wire RTD,
normally open relay contact, and normally closed relay contact
wiring connections. Additionally, input and output channel
terminals are color coded for easier recognition. The markings
and color coding together allow wiring the input and output
channels without requiring any additional documentation.
