LED D1 and display U6 indicate the status of the board. Ta bl e 13 illustrates
the possible states for D1.
Replacing the External Input/Output Board
1. Disconnect and lock out all medium voltage and control voltage power
to the drive.
2. Mark the location and orientation of all the plugs, cables, and
connectors into the XIO board. Use the electrical drawing as a reference.
3. Ground your static strap, and disconnect all of the power 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
secures the board. The assembly does not come with the new board, so
you must remove the old board from the assembly and install the new
board 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 both system and medium voltage
tests to ensure the new board functions properly.
