3.2.1.3 Recommended Control and Signal Wire Sizes
The recommended wire size to connect I/O signals to the terminal strip on the AC Line
I/O board is 20 to 14 AWG, (2 to 0.5 mm
2
). Recommended terminal tightening torque
is 0.5 Newton-meters (4.5 in-lbs). Operator controls can be up to 303 meters (1000
feet) from the LiquiFlo drive.
