Power Distribution 115VAC Control Voltage – Figure 2.9 illustrates the distribution of
115VAC control voltage within the Bulletin 1395. Single phase 115VAC
control voltage, provided from an external source by the user enters the
drive at TB2-2 and 3. Fuse F3 provides protection against short circuits on
the 115VAC input to the drive.
