4.3 Power Wiring Reference
Even though the Main 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 Main Unit is wired together with the DSP1500 Servo Controllers.
Note that the Main Unit is using one phase while the Servo Controllers use three phases.
Note: Diagram shown with the Main Unit wired using same cable used for SAN Unit for
standardizing components. Pin #2 is not wired internally on the Main Unit.
