The following table shows types of cables. It is used in conjunction with the preceding
tables.
The following table specifies the appropriate cables for CN1 and CN2 digital torque amplifier
connectors. Wire sizes were selected with the expectation of three cables per bundle, at an
ambient temperature of 40°C, at the rated current level.
