[Installation Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Precautions for using C Controller modules]
● When mounting a C Controller module, make sure to attach the connector cover included in a base
unit to the module connector of the second slot to prevent entrance of foreign material such as dust.
[Installation Precautions]
CAUTION
● Use the programmable controller in an environment that meets Page 84 General Specifications in this
manual. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of
the product.
● To mount a module, place the concave part(s) located at the bottom onto the guide(s) of the base unit,
and push in the module until the hook(s) located at the top snaps into place. Incorrect interconnection
may cause malfunction, failure, or drop of the module.
● To mount a module with no module fixing hook, place the concave part(s) located at the bottom onto
the guide(s) of the base unit, push in the module, and fix it with screw(s). Incorrect interconnection
may cause malfunction, failure, or drop of the module.
● When using the programmable controller in an environment of frequent vibrations, fix the module with
a screw.
● Tighten the screws within the specified torque range. Undertightening can cause drop of the screw,
short circuit, or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
● When using an extension cable, connect it to the extension cable connector of the base unit securely.
Check the connection for looseness. Poor contact may cause malfunction.
● When using an SD memory card, fully insert it into the SD memory card slot. Check that it is inserted
completely. Poor contact may cause malfunction.
● Securely insert an extended SRAM cassette into the cassette connector of the CPU module. After
insertion, close the cassette cover and check that the cassette is inserted completely. Poor contact
may cause malfunction.
● Do not directly touch any conductive parts and electronic components of the module, SD memory
card, extended SRAM cassette, or connector. Doing so can cause malfunction or failure of the
module.
[Precautions for using Safety CPUs]
● Use the CC-Link IE Field Network remote I/O module (with safety functions) and CC-Link IE Field
Network remote I/O module in an environment that meets the general specifications in the
corresponding manuals (CC-Link IE Field Network Remote I/O Module (With Safety Functions) User's
Manual and CC-Link IE Field Network Remote I/O Module User's Manual). Failure to do so may result
in electric shock, fire, malfunction, or damage to or deterioration of the product.
● Securely fix the CC-Link IE Field Network remote I/O module (with safety functions) and CC-Link IE
Field Network remote I/O module with a DIN rail or module fixing screws. Tighten the screws within
the specified torque range. Undertightening can cause drop of the screw, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
