Connect to Power
Use the supplied connector to connect to the AC
supply according to the diagram below. Use 16
AWG wire for Line (L) and Neutral (N). Use 14 AWG
for Earth Ground (G).
AC input voltage must be
selected by switch.
Check
input voltage avoiding damage
before
power on!
80VAC<Input AC Voltage<135VAC:
set the switch on 115V Status
135VAC<Input AC Voltage<265VAC:
set the switch on 230V Status
The SRAC2 has an internal 5A fast acting fuse.
Care should be taken when working with high voltages.

Selecting the Motor
Each position of the 16-bit rotary selects a different motor, automatically setting the configuration parameters
in the drive. The SRAC2 drive comes programmed with up to 16 typical motors as factory
defaults. Drives can be customized with specially selected motors when required. Available
options are listed on the drive label. Each motor in the loaded database has unique settings to
optimize the anti-resonance.
If the motor selection is changed, the drive power supply will need to be cycled.
