3.2.2.3 Recommended Control and Signal Wire Sizes
The recommended wire sizes to connect I/O signals to the terminal strip on the
Regulator board and RMI board are shown in table 3.6. 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.
