5.If a bypass is connected, place the Mode Selector 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.
7g Confirm directional rotation.
8.Check motor rotation direction in bypass as follows.
8a Momentarily bump motor in bypass.
8b Confirm directional rotation.
8c If incorrect, stop drive, remove power, and lock out.
8d Reverse connection of L1 & L2 input power leads to the main disconnect. Do not change motor leads.
8e Confirm directional rotation.
9.Check motor current in drive mode on the motor terminals.
9a Put the unit in drive mode.
9b Check motor current on motor terminals 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
within FLA of drive and balanced within 3%. If incorrect, see 7.1 Start Up Trouble- shooting for isolation procedures.
10.Check motor current in bypass mode on the motor terminals.
10a Put the unit in bypass mode.
10b Check full load amps on terminals T1, T2, and T3. Verify the motor amps are within motor FLA rated current and balanced within 3%. If incorrect, see
7.1Start Up Troubleshooting for isolation procedures.
For steps
11.Check operation of any optional functions to confirm that they work, as applicable. Options may include run permissive, fire mode, common start/stop, or others.
