Important: Slide the side access panel
up into the open position. Remove the
jumper from the AC position (Default)
and reinstall it into the 24 V position
(A.P.S.). The instruction on the side of
the drive will show which position to put
the jumper.

Alternate Power Supply Wiring (Epsilon Only)
Enabling APS power is done by sliding open the access panel on the side of the drive. Then
move the jumper into the APS position using needle nose pliers.
Use static control procedures when handling the jumper inside the drive case.
The APS input is isolated from all other circuits on the Epsilon drive including the DC bus,
logic and I/O. This premits you to use one common 24 VDC power supply for multiple drives
without concern for ground loops and noise coupling between drives. The APS connection
will generate some high frequency ripple (.25 Amps at 80 khz) on the APS power lines. This
may disturb sensitive equipment that shares the same power supply.
