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 referenced to the Drive AGND; isolate them if you require them to
drive outside the frame enclosure.

Auxiliary +24V Power Supply
The DC/DC converter has a built-in isolated 24V power supply (Connector P3).
Use this supply for any equipment requiring up to 24 watts at +24 volts. You can
also use it 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.
Replacing the ACB Analog Control Board
To replace the ACB Analog Control Boards:
1. Isolate and lock out all power to the drive.
2. Remove the transparent sheet on top of the Drive Processor Module and
the Drive Processor Module itself before removing the ACB. Remove the
transparent sheet on top of the DPM by removing the 4 screws.
