NOTE: This drawing is duplicated in Installation – Step 3: DIP Switches, later in this chapter.4. CONNECT AC POWER

The E-AC Drive does not have an ON/OFF switch. When you connect

power, the automatic test will begin—the drive will turn on and the motor

will start turning. Therefore, before you apply power to the E-AC Drive:

• Properly secure the motor.
• Do not attach a load to the motor shaft.

To apply power, connect one end of your power cable to the drive’s 120V

and terminals. Connect the other end to a grounded 120VAC power

source. (Further instructions are presented later in this chapter.)

5. OBSERVE THE AUTOMATIC TEST

Your E-AC Drive should now be running in the automatic test mode.

•The motor shaft should rotate at approximately one revolution per second
(1 rps) in an alternating mode, until you remove power.
•LED Operation – observe the LEDs on the front panel:
PWR LED (power; green) should illuminate
FLT LED (fault; red) should be off
6. STOP THE AUTOMATIC TEST

Disconnect power to stop the motor. Set DIP SW1-#1 to off. (Return DIP

switches of previously configured drives to original settings, if desired.)
