The Isolator Voltage jumper (J3) is located on the Power Board (see Figure 2-2). It
configures the isolated analog output for either voltage that is ranged by an internal +15
volt reference or for voltage that is auto-ranged by the voltage level of the motor drive.
The auto-range voltage position is the default configuration for the Isolator Voltage
jumper.
NOTE: In most cases, the default configuration will be appropriate for your application
and it will not be necessary to re-configure.
If the motor drive does not have an external voltage reference, re-configure the Isolator
Voltage by moving the jumper from the default auto-range voltage position (1) to the
internal +15 volt reference position (2).
