3.5.2 Changing the drive rotation
The bevel-gear Thimble assembly or the Thimble gear assembly in the UMB permits either clockwise (CW)
or counterclockwise (CCW) rotation. Before installing EC350, note whether the output shaft of the meter
rotates CW or CCW. You can change the driver rotation by positioning the Thimble gear assembly of
EC350 to match the meter rotation.
