2.4.1 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 2-1. The auxiliary supply is
wired to terminal block X01 (see Figure 2-17).
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 2-1.
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 3 - Control system,
Figure 3-2 for terminal block location.
