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! To avoid danger, or damage to the drive, on IT systems and corner
grounded TN systems, see section Disconnecting the internal EMC filter on page 23.
