Start-up Procedure, Electronic Bypass (E-Bypass)

Step Check
1 Verify that all three input phases are connected to the input fuse block (or circuit breaker depending upon model) and
that the motor leads are connected to the output terminals of the overload relay only.
NOTE: The M1 (Bypass) contactor and the M2 (Output) contactor outputs are connected together at the factory.
2 Verify that all factory connections within the bypass are tight, as factory connections can loosen during shipment.
3 Dial in the current limit on the overload in accordance with the connected motor.
4 Apply power to the drive with E-Bypass option using the main disconnect. Verify that all three phases are present, and
that the input voltage is correct for the system.
5 The keypad illuminates and the Startup Wizard of the drive is active. Complete the Startup Wizard. When prompted for
Bypass Wizard, answer YES.
NOTE:
This should be activated when the unit is first powered up. If not, reset the drive to factory-default to return to a good,
known starting configuration. This can be completed by selecting the following:
User Settings (6)/Parameter Backup (6.6)/Restore Factory Defaults (6.5.1)/Activate.
See Startup Wizard for detailed information.
6 During the execution of the Bypass Wizard, select Electronic.
NOTE:
A Remote Safety 1 and Remote Safety 2 fault will occur. Press the Back/Reset button once to return to the wizard.
Configure the Remote Safety 1 (3.5.1.44) and Remote Safety 2 (3.5.1.45) once the Bypass Wizard is complete. See
Bypass Wizard for detailed information..

Press the HAND/AUTO button on the drive. Select Drive, and press OK. Select Hand, and press OK. When Activate
displays, press the OK button. Enter a setpoint of at least 5 hertz. Press the green I button to start the motor. Verify that
the motor rotation is correct for the application. Press the red O button to stop the motor.
NOTE: If the motor rotation is incorrect, do not correct now. Complete Step 10 first, then see Step 11 for corrective
actions.
8 "Bump" the unit into Bypass mode by completing the following:
Press the HAND/AUTO button on the drive. Select Bypass, and press OK. When Activate displays, press OK. Then,
quickly press the HAND/AUTO button on the drive. Select OFF, and press OK. When Activate displays, press OK. Verify
that the motor rotation is correct for the application.
NOTE: If the motor rotation is incorrect, do not correct now. See Step 11 for corrective actions.
9 If the motor rotation was incorrect in either Step 9 or 10, remove power to the bypass assembly using the disconnect
switch. Wait 5 minutes to allow for the drive's DC Bus to discharge. See Motor Rotation Correction Wiring for required
changes. Apply power, and repeat Steps 9 and 10 to verify proper rotation again.
10 Press the HAND/AUTO button on the drive. Select Drive, and press OK. Select Auto and press O. When Activate
