5.5.8 User I/O Interface
The user I/O is a standard user interface, provided on the power supply. It provides the
ability for the customer to make their own interface for special control or reporting needs.
The interface cable has an HD44 female D-shell connection on the rear of the power
supply. The electrical interface outputs may be configured for open collector mode or for
signal mode (signal voltage levels as indicated), by setting the user I/O DIP switch.
DIP switch SW1 for the user I/O is located next to the J3 on the back of the 2000Xc-series
power supply. User I/O interface cable pinout is listed in Table 5.5.

CAUTION
All unused wires must be individually electrically isolated from each
other. Failure to properly isolate or incorrect wiring can cause the
system controller board to fail.
CAUTION
Ensure GND pins and +24 V pins are wired correctly. Failure to
properly wire these pins will cause damage to the system controller
board.
