5. If multiple I/O expansion modules are to be installed, remove the right-side plastic cover
on all but the last module. For example, if two I/O expansion modules will be installed,
remove the cover on the first module but not the second.
NOTE:
The right-most module must always have the plastic cover over the D-SUB 9 connector
installed.
6. Repeat steps 2.- 4. for all expansion modules, placing the communication expansion
module (maximum of one) on the left side of the base unit and I/O expansion modules
(maximum of three) on the right side of the base unit.
7. Slide the communication expansion module to the right against the base unit. A slight
resistance will be felt as the D-SUB 9 connectors mate.
8. Slide any I/O expansion modules to the left against the base unit. A slight resistance will
be felt as the D-SUB 9 connectors mate.
9. Repeat step 8. for any additional I/O expansion modules. A maximum of three modules
can be attached to a base unit.

Removing modules from the mounting rail

To remove a Nanoline base unit or module from the mounting rail:
CAUTION:
Always disconnect power to the system at the power source before removing any
components from the mounting rail. Do not remove power wires from the connector
without disconnecting power at the source.
1. Disconnect power to the base unit at the power source. If input/output wiring is to be
disconnected, disable any separate power supplies attached to affected I/O devices.
2. Disconnect the power supply wires to the base unit.
3. If expansion modules are to be removed, disconnect any input/output wiring to I/O
expansion modules or network connections to the communication expansion module.
If only the base unit is to be removed, it may be possible to slide the expansion modules
to the side, if sufficient wire length and mounting rail space are available, without
disconnecting I/O wires.
4. If expansion modules are installed, slide them away, one at a time, from the base unit.
Slide communication expansion modules to the left and I/O expansion modules to the
right.
NOTE:
Do not slide multiple I/O expansion modules as a group as damage to the interfacing
connectors may occur.
