Before Applying Power to the Drive
1. Confirm that all inputs are connected to the correct terminals and are
secure.
2. Verify that AC line power at the disconnect device is within the rated
value of the drive.
3. Verify that any digital control power is 24 volts.
4. Verify that the Sink (SNK)/Source (SRC) Setup DIP Switch is set to

IMPORTANT Read the General Precautions section before proceeding.
ATTENTION: Power must be applied to the drive to perform the following
start-up procedures. Some of the voltages present are at incoming line
potential. To avoid electric shock hazard or damage to equipment, only
qualified service personnel should perform the following procedure.
Thoroughly read and understand the procedure before beginning. If an event
does not occur while performing this procedure, Do Not Proceed. Remove
All Power including user supplied control voltages. User supplied voltages
may exist even when main AC power is not applied to the drive. Correct the
malfunction before continuing.
IMPORTANT The default control scheme is Source (SRC). The Stop terminal is jumpered (I/
O Terminals 01 and 11) to allow starting from the keypad. If the control
scheme is changed to Sink (SNK), the jumper must be removed from I/O
Terminals 01 and 11 and installed between I/O Terminals 01 and 04.
