text: <s>[INST] Safe Off Wiring for PowerFlex 40P I have an MSR138DP and PF40P, with an E-stop. Is there a working electrical drawing that I can have to design a Cat 1 stop? The exisiting drawing on the DriveGuard manual does not explicitly state what the 'Enable' input is located on the PF40P? Please help. [/INST] There is actually two steps to installing the Driveguard option. You remove the driveguard plug which just protects the pins that a terminal strip plugs on to and then remove the drive Enable jumper. The driveguard is really just a relay that is energized by a field device (e-stop pull-cord, etc) and the contacts enable the drive to run. You have to remove the front plastic cover on the drive to get to the pins. Page 7-8 show the location on a 40P drive. I/O terminals 1, 2, and 3 are dedicated to Stop. Start, and Reverse operation. The driveguard really takes the place of the enable jumper which, I believe, disconnects gating power to the IGBT's. \\n </s>
