ATTENTION: A contactor or other device that routinely disconnects and
reapplies the AC line to the drive to start and stop the motor can cause drive
hardware damage. The drive is designed to use control input signals that will
start and stop the motor. If used, the input device must not exceed one
operation per minute or drive damage can occur.
