External Input/Output Board Replacement
To replace the External Input/Output Boards:
1. Ensure that all medium voltage and control voltage power to the drive is
isolated and locked out.
2. Note and Mark the location and orientation of all the plugs, cables, and
connectors into the XIO board. Use the electrical drawing as a reference.
3. Using your static strap, disconnect all of the connections.
4. Remove the XIO board assembly from the low voltage control cabinet.
The XIO board mounts on a DIN rail, so a special 3-piece assembly is used
to secure the board. The assembly does not come with the new board, so
the old board needs to be removed from the assembly and the new board
installed in its place.
5. Install the new XIO board assembly in the low voltage control cabinet.
6. Reconnect all connections and verify the locations.
7. Apply Low Voltage power and complete a System Test and Medium
Voltage tests to ensure the new board functions properly.
