Field Wiring
•
If this distance is not possible, longer wire runs with shielded wire are allowed up to 30 m
(100 ft). Connect the shield to any
0V
terminal on the controller, making sure to isolate
the shield on the other end. Failing to do so creates ground loops.
•
When possible, route the wiring inside metal piping and ground the piping for better
results.
•
Avoid running any analog signals near sources of electric noise such as: motors,
ballasts, fluorescent lamps, variable frequency drives, high energy contacts, RF (radio
frequency) transmitters, microwave ovens, and any other equipment that generates
electromagnetic interference.
•
Keep a minimum distance of 30 cm (1 ft) between analog output wiring and any
conductor carrying more than 24 VAC.
•
Follow good wiring and installation practices, and follow all local regulations and
electrical codes.
•
Use either of the terminals labeled
0V
to connect the return signal or common.
