• If the 9900 Base Unit will be mounted in a panel, plug-in
modules may be installed either before or after the base unit
is mounted.
• If the 9900 Base Unit will be mounted using the
accessory wall mount kit (3-9900.392), install plug-in
modules first.
• If the Direct Conductivity/Resistivity Module or Current
Loop Module will be included in your unit, install the
Modbus module first and then install Conductivity/Resistivity
Module over the Modbus Module.
• Attach the output connector to the terminal block on the
Modbus Module prior to installing in the 9900. When
inserting the Modbus module with the wiring connector
ensure the wires are not pinched by the power or open
