5.4 Dimensions for 230V MMC Smart Drive
This section contains dimensional information on the narrow width (-DN) Digital MMC-
SD drive, the standard width (-D) Digital MMC-SD drive, and the Analog Interfaced
drive (no letter suffix). Use this information to determine mounting hole locations on
the drive panel.
When locating the drive on the panel, observe the clearance requirements found in
Table 3-1 on page 21. Mount the drive to the panel with #10 bolts and #10 star
washers (to ensure proper ground connection).
