Assembling Modules
The following example demonstrates the procedure for assembling the 40-I/O type CPU module and the AS-Interface
master module together. When assembling the 20-I/O relay output type CPU module, take the same procedure.
1. When assembling an AS-Interface master mod-
ule, remove the expansion connector seal from
the 40-I/O type CPU module.
2. Place the CPU module and AS-Interface master module
side by side. Put the expansion connectors together for easy
alignment.
3. With the expansion connectors aligned correctly and the
blue unlatch button in the down position, press the CPU
module and AS-Interface master module together until the
latches click to attach the modules together firmly. If the
unlatch button is in the up position, push down the button to
engage the latches.
Note: When assembling other I/O modules with the AS-Inter face
master module, take the same procedure.
Disassembling Modules
1. If the modules are mounted on a DIN rail, first remove the
modules from the DIN rail as described on page 3-3.
2. Push up the blue unlatch button to disengage the latches,
and pull the modules apart as shown.
Note: When disassembling other I/O modules from the AS-Inter-
face master module, take the same procedure.
Caution
• Assemble MicroSmart modules together before mounting the modules onto a DIN rail. Attempt
to assemble modules on a DIN rail may cause damage to the modules.
• Turn off the power to the MicroSmart before assembling the modules. Failure to turn power off
may cause electrical shocks.
