5. Route the other end of the ControlNet cable through the bottom of the
drive, and insert its ControlNet cable plug into the mating option module
receptacle. We recommend using a 1786-TPS straight tap.
IMPORTANT Remove power from the drive before installing the option module in the drive
control pod.
IMPORTANT After inserting the option module into Port 4, 5, or 6, make sure to tighten the
module screws to the drive control pod to properly ground the module to the
drive. Torque both screws to 0.45…0.67 N•m (4.0…6.0 lb•in).
ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain high
voltages that can cause injury or death. Remove power from the drive, and then
verify power has been discharged before connecting the option module to the
network.
