CAUTION: Jumpering CTB1-35 and CTB1-36 together will not allow for motor
flux to decay prior to applying AC line power to the motor in the event of a drive
fault. The absence of the 10-second time delay can result in a devastating
torque pulse which can damage your motor, driven load and/or installation. The
AF 650 GP & Bypass panel does not have a line synchronizing function to
permit a smooth switchover to AC line power, therefore a time delay is the only
way to ensure a safe transition.
