5. To apply power, turn main disconnect (and drive disconnect, when applicable) to ON position. If a bypass
is connected, place bypass in drive mode.
6. Enter drive programming data per instructions in drive instruction manual.
In steps 7 through 11, for a bypass with a contactor motor selection (CMS) option, put the motor selector switch
in motor 1 position. Repeat the procedure for motor 2 with the switch position in motor 2. For dual motor
applications, check both motors at same time.
7. Check motor rotation direction in drive control as follows.
a. Put panel in drive mode.
b. Hand start drive at minimum speed (see drive instruction manual for details).
c. Confirm directional rotation.
d. If incorrect, stop drive, remove power, and lock out.
e. Reverse connection of any 2 of 3 motor leads at terminal. Do not change incoming power leads.
f. Remove lockout and apply power.
g. Confirm directional rotation.
8. Check motor rotation direction in bypass as follows.
a. Momentarily bump motor in bypass.
b. Confirm directional rotation.
c. If incorrect, stop drive, remove power, and lock out.
d. Reverse connection of any 2 of 3 input power leads at terminal. Do not change motor leads
f. Confirm directional rotation.
NOTICE
CAUTION FULL SPEED OPERATION! ENSURE THAT THE MOTOR, SYSTEM, AND ANY ATTACHED EQUIPMENT IS
READY FOR FULL SPEED OPERATION. USER ASSUMES ALL RESPONSIBILITY FOR ASSURING SYSTEM IS ABLE
TO SAFELY RUN AT FULL SPEED. FAILURE TO ENSURE THAT THE MOTOR, SYSTEM, AND ANY ATTACHED
EQUIPMENT IS READY FOR FULL SPEED OPERATION COULD RESULT IN EQUIPMENT DAMAGE.
9. Check full load amps in drive mode on motor terminals.
a. Put unit into drive mode.
b. Check full load amps on motor terminals T1, T2, and T3. Verify motor amps are within drive and motor rated
current and are balanced within 3%. If incorrect, see Troubleshooting Section in this manual for isolation pro-
cedures.
c. Check full load amps on input terminals L1, L2, and L3. Verify that current is within FLA of drive and balanced
within 3%. If incorrect, see Troubleshooting Section in this manual for isolation procedures.
10. Check full load amps in bypass mode on motor terminals.
