Removing the EXL10 OCS I/O Cover

WARNING: Power, including I/O power must be removed from the unit prior to removing the back
cover. Failure to do so could result in electrocution and/or damage to equipment.
Some I/O configurations require jumper settings to be changed in the EXL10 OCS unit. Examples of these
settings are setting positive or negative logic on digital inputs or setting current or voltage on analog
inputs.
Each EXL10 OCS I/O jumper is set to a factory default. Refer to the EXL10 datasheet to find the default
setting to determine if a jumper change is necessary for a particular application.
To remove the I/O cover of the EXL10 OCS, remove the four (4) Phillips screws from the I/O back. It may
help to place the EXL10 OCS unit face down on a clean work surface. Once the four screws are removed
the I/O cover can be lifted straight off.
