a. As an Output, indicates that the AC Input Power to the drive is OK. As an Input,
instructs the drive to run even though AC Input Power is not present. This is typ-
ically used when two drives share bus power that is provided by the drive con-
nected to AC Input Power. See
section A.1 on page 301 for more information.

b. As an Output, indicates that the drive’s Shunt Output is active. As an Input,
instructs the drive to activate its Shunt Output. Whenever the Shunt On signal is
active (24Vdc nominal), the user-supplied shunt resistor (installed between Ba+
and Ba-) is connected across the DC bus. See
section A.1 on page 301 for
more information.

CAUTION
A possible ignition hazard within the MMC 460V Smart Drives exists if exces-
sive current is drawn from the 24 VDC powering the MMC Smart Drive. To
prevent this possibility (due to improper wiring or 24 VDC supply failure), a
fuse should be used in series with the 24 VDC to the MMC Smart Drive (4 A
max). In addition, the 24 VDC shall be supplied by an isolating source such
that the maximum open circuit voltage available to the MMC Smart Drive is
not more than 30 VDC.
