Auxiliary power supply
The ACS2000 drive system requires an auxiliary
power supply to provide power for the internal
controls, pre-charge system, and fan(s). This power
is supplied via a 3-phase 480 V power feed (400 V
and 600 V auxiliary supply voltages are available by
option). In the event of power interruption, the
internal controls power supplies are buffered to
ride through for 0.2 seconds. If power is not
restored, the drive will perform a controlled
shutdown and indicate fault.
The power draw of the drive is shown in Table 4.
The auxiliary supply is wired to terminal block X01
(see Figure 34).

See Appendix P - Integral Input Contactor
Disconnect, located on the CD, for detailed
information on drives with this option.
The upstream disconnect may be the integral input
contactor disconnect option. The Kirk key for this
option is located behind the door of the
disconnect section.
Note: Auxiliary power may be provided by
the integral input contactor disconnect on
drives with this option.
Note: The power feed for the auxiliary
supply shall be protected with suitable
branch circuit protection rated
according to Table 4.
See Appendix E - Wiring diagrams, located
on the CD, for information on the
configuration of the auxiliary power
interface present in the drive.
See Rating label of the drive located on the
back of the control compartment door for
information on the rated voltage(s) and
current(s) that the auxiliary power must
match. See Chapter Control system,
Figure 34 for terminal block location.
