Page 233 ACH550-UH User’s Manual Grounding and Routing Background Motor cables require extra care in grounding and routing. The reasons have to do with the following factors: • Parasitic capacitance – Capacitors are, essentially, conductors that don’t touch, but are in close proximity to each other. So, for example, there is a weak capacitive connection between cables and any conductors they are near.
Page 234 ACH550-UH User’s Manual • Power Shield Cable – For power shield cable details, see "Motor Cable Requirements for CE & C-Tick Compliance" below. Grounding See "Ground Connections" in "Input Power Connections" above. For CE compliant installations and installations where EMC emissions must be minimized, see "Effective Motor Cable Screens"...
