Wiring and EMC considerations
Determine electro-magnetic compliance (EMC) requirements
per local codes. In general:
• Follow local codes for cable size.
• Keep these three classes of wiring separated: input power
wiring, motor wiring and control/communications wiring.
• Check the operational limits for the allowed maximum motor
cable length in section
• If the installation must meet the European EMC Directive
requirements (see section
EN 61800-3 (2004)
for the allowed maximum motor cable length in section
connection
Note: Non-proper wiring is the source of the majority of EMC
problems. Please follow the instructions to avoid these
problems.
