USE 18 AWG WIRE MINIMUM. TO MINIMIZE

INTERFERENCE PROBLEMS:



USE SHIELDED WIRE ON ALL ANALOG INPUTS

AND OUPUTS. DO NOT RUN 0-10 VOLT DC

SIGNAL WIRING IN THE SAME CONDUIT AS

LINE VOLTAGE WIRING OR WITH WIRING

THAT SWITCHES HIGHLY INDUCTIVE LOADS

SUCH AS CONTACTOR AND RELAY COILS.

GROUND ONE END OF THE DRAIN (SHIELD)

WIRE.



WHEN 0-10 VOLT DC SIGNAL WIRING MUST

CROSS CLOSE TO CABLE OR NONMETALLIC

CONDUIT CONTAINING LINE VOLTAGE

WIRING OR WIRING THAT SWITCHES HIGHLY

INDUCTIVE LOADS, IT MUST CROSS

PERPENDICULAR (90 DEGREES) TO IT.



KEEP THE 0-10 VOLT DC SIGNAL WIRING AS

SHORT AS POSSIBLE.
