FEC AFC1500 - Manual (Page 17)

Power wiring reference
Even though the Multi Unit power input allows it to connect to 120 VAC- 220
VAC power lines, typically the unit is connected to the same power source
that the SAN Units are connected to. (200 to 220 VAC ± 10%) . In the
example wiring diagram shown below there are two power branches: one is
for the control circuitry connected to 120 VAC and the other is for the SAN
power circuitry, connected to 220 VAC. For convenience, the Multi Unit is
wired together with the AFC1500 Servo Controllers. Note that the Multi Unit
is using one phase while the Servo Controllers use three phases.
