* These values do not apply when this hardware is used on power modules, such as IGBTs, and diodes). For the required
torque values in these instances refer to the System drawings provided with the drive.
** These sizes are only torqued when used on ground wire.
*** #8 bolts used in secondary connections on CTs are torqued to 15 in-lbs.
Note
Input Conductor Sizing
Be sure to size the input conductors appropriately for the particular application, taking into
account the length of the input power feed as well as local electrical code and local standards.
Labels located near the connections recommend the use of 75
