10 MOUNTING AND INSTALLATION
MELSEC-ST
(a) Precautions for installing slice modules
1) Wire the base module terminal blocks before installing the slice
modules.
2) A coding element is mounted to the bottom of each slice module for
preventing mis-insertion prior to shipment.
Once a slice module is mounted to a base module, the female part of
the coding element is attached to the base module and the male part
remains the slice module.
This determines the corresponding slice/head module for each
head/slice module. Therefore, from the second insertion, the slice
module cannot be mounted onto the base module other than the one
that matches the element.
Make sure to confirm that the slice module matches the base module
before mounting. When inserting a slice module to a base module first,
there may be some resistance, as the female part of the coding
element is attached to the base module. Make sure to insert the slice
module into the base module until it stops.

3) If the slice module cannot be mounted onto the base module, do not
push it with force. The slice module may not match the base module. In
this case, check the coding element hole, etc., whether they match or
not.
