Power Distribution
115VAC Control Voltage - Figure 4.11 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 TB5-4 and 5. Fuse F4 provides protection against short circuits on
the 115VAC input to the drive terminal block TB6 (an internal terminal
block).
