Assembling Modules
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.
The following example demonstrates the procedure for assembling the all-in-one 24-I/O type CPU module and an I/O
module together. When assembling slim type CPU modules, take the same procedure.
1.
When assembling an input or output module,
remove the expansion connector seal from the 24-
I/O type CPU module.
Unlatch Button
2.
Place the CPU module and I/O 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 I/O 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.
Disassembling Modules
Caution
Remove the MicroSmart modules from the DIN rail before disassembling the modules. Attempt
to disassemble modules on a DIN rail may cause damage to the modules.
Turn off the power to the MicroSmart before disassembling the modules. Failure to turn power
off may cause electrical shocks.
Unlatch Button
1.
If the modules are mounted on a DIN rail, first remove the
modules from the DIN rail as described on page 3-8.
2.
Push up the blue unlatch button to disengage the latches, and
pull the modules apart as shown. When disassembling slim
type CPU modules, take the same procedure.
