The following diagram shows the terminal layout for frame size R3, which, in
general, applies to frame sizes R1
…
R6, except for the R5/R6 power and ground
terminals.
WARNING! For IT systems and corner grounded TN systems, disconnect the
internal EMC filter by removing:
- On ACS550-01: screws EM1 and EM3
- On ACS550-U1: screw EM1 (drive is shipped with EM3 already removed).
