Motor and AC Power Connections

The three-phase motor terminal connections are made at connections A, B, and C. Motor
Connections A, B, C and its Protective Ground must be made with #14 AWG wire
rated @ 300 Volts. Motor frame and shield connects to
Input voltage connection to the Soloist is made at the AC1 and AC2 terminals. Earth
ground is connected to
must be made with #14 AWG wire rated @ 300 Volts.

External fuses or circuit breakers (15 Amps maximum, time delay type) are required for
the AC1 and AC2 AC inputs for protection and must be located near the Soloist. For
optimum protection, use 10 Amp protection devices (15 Amp devices are required in
applications requiring maximum power).
The AUXPWR input is an option, but, if present must be powered. For example, if the
AC bus input voltage is less than 85 VAC at TB102 AC1, AC2, the optional -AUXPWR
control power input must be present and powered for keep alive operation. This feature
can also be used when an external emergency stop circuit is present, which removes bus
power (as illustrated in Section 2.6.1 In either case, the -AUXPWR input provides keep
alive or control power to the drive at all times.
The AUXPWR input is located on the side of the unit, as shown in the previous
illustration. The supply connections to the AC1 and AC2 -AUXPWR inputs and the
protective ground must be at least #18 AWG wire rated @ 300 V (3 Amp external fusing
is required for AC2. The AC1 is fused internally at 3 Amps).
