text: <s>[INST] 1305 replaced by Powerflex 525 Summary: Main RCD Tripping after drive replaced.Hi We have recently replaced a 1305-BA09 with a Powerflex 25B-D010N114 in an 18 year old panel, since doing this we have started to get random tripping of the main RCD in the panel. Has anyone any experience of this happening and reasons for it. Thanks Graham [/INST] Tell us about the motor leads. Are you using VFD cable? Is the shield landed directly on the VFD (as it should be)? Is the motor end of the shield also landed on the motor (as it should be)? Is the ground wire running back from the motor landed directly on the VFD (as it should be)? \\n </s>
