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.
