Switch in drive mode. Apply power by turning
the main disconnect switch to the ON position.
6. Enter drive programming data per the drive
instruction manual.
7. Check motor rotation direction in drive control as
follows.
7a Put panel in drive mode.
7b Hand start drive at minimum speed (see
drive instruction manual for details).
7c Confirm directional rotation.
7d If incorrect, stop the drive, remove
power, and lock out.
7e Reverse connection of T1 & T2 motor
leads. Do not change incoming power
leads.
7f Remove lockout and apply power.

T1, T2, and T3. Verify the motor amps
are within drive and motor rated current
and are balanced within 3%. If incorrect,
see 7.1 Start Up Troubleshooting for
isolation procedures.
9c Check input current on input terminals
L1, L2, and L3. Verify that current is
BAS-SVX49A-EN
within FLA of drive and balanced within
