[Installation Precautions]
●
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.
[Installation Precautions]
●
Use the programmable controller in an environment that meets the general specifications in the
manual "Safety Guidelines" included in the base unit. 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
mounting 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).
●
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 circuiA-5t, 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 incorrect input or output.
●
When using an SD memory card, fully insert it into the 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 a 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 may cause malfunction or
failure of the module.
[Wiring Precautions]
●
Shut off the external power supply (all phases) used in the system before installation and wiring.
Failure to do so may result in electric shock or damage to the product.
●
After installation and wiring, attach the included terminal cover to the module before turning it on
for operation. Failure to do so may result in electric shock.
