1) Category C1 with conducted emissions only. Radiated emissions are not
compatible when measured with the standard emission measurement setup
and must be measured on cabinet and machine installations for each case.
Notes:
• Remove the EMC screw to disconnect the internal EMC filter.
Refer to EMC filter disconnection
• Radiated emissions are according to C2 with ACS380-042x
drives. For ACS380-040x drives, use a metal enclosure to fulfill
radiated emissions C2 limits with an external EMC filter.
• For 3-phase 380...400 V drives, the maximum motor cable lengths
are according to C3 in the above table with an internal EMC filter.
• For 1-phase and 3-phase 208...240 V drives, the maximum motor
cable lengths are according to the motor cable length table on
page 107. The EMC category for these drives is C4 (no EMC).
