text: <s>[INST] PowerFlex DC Interposing Relay Summary: Recommendations for Interposing Relay on Frame C drive? Customer says tech support said an interposing replay for the main contactor on a Frame C drive would help with contactor faults. KB document 32187 indicates that we don't recommend an interposing relay for a 100C contactor. The customer didn't have any information sent by tech support. Do we, or don't we, recommend an interposing relay for a Frame C drive? If we do, what kind of relay and is there a wiring diagram? [/INST] You can install a 50 mF capacitor between the digital output driving the main contactor and common to fix this issue. There is a tech note out there but I do not have it handy. \\n </s>
