Chapter 1
Control Circuit Input Power
The control circuit must be powered by an external 230V AC or 115V AC single
phase power supply. For frame B and C drives only, a jumper is required between
terminals SA and SB for 115V AC control input power. For frame B drive SA-SB
terminal block location, see
Figure 43
on page
67
. For frame C drive SA-SB
terminal block location, see
Figure 43
on page

.
Note:
If the SA-SB terminal block is not configured for the correct input voltage,
“No Fault” (F0) will display on the HIM, if installed.
