Non-Isolated Process Outputs

The drive supplies four non-isolated -10/0/+10 V outputs for customer
use. These outputs can drive loads with impedances as low as 600
ohms. These outputs are all referenced to the Drive AGND and
therefore should be isolated if they are required to drive outside the
PowerFlex ‗C‘ frame enclosure.

Auxiliary +24V Power Supply

An Isolated 24V Power Supply is built into the DC/DC converter
(Connector P3). This supply may be used for any customer supplied
equipment requiring up to 24 watts at +24 volts. This supply may
also be used to power any custom drive options, such as isolation
modules for additional Process Control Outputs. The health of this
power supply is monitored in the drive.
