text: <s>[INST] PowerFlex 40 trips GFCI I have a 120v PowerFlex 40 that trips a GFCI when you press the start funtion. Works fine when on a non GFCI circuit. Whats causing the GFCI to trip? [/INST] This is quite normal, and usually it happens due to filtering...the filter works by filtering the noise down to earth which would cause the GFCI to trip. Follow the instructions in the User Manual, page 1-7, and use a Type B RCD Also take a look to the following technotes: Aid 40028 - Aid 40632 Hope this helps… - fuzzy logic \\n </s>
