[INSTALLATION PRECAUTIONS]
Use the module in the environment given in the general specifications of CPU
module user's manual.
Using the programmable controller outside the range of the general specifications
may result in electric shock, fire or malfunction, or may damage the product.
Load a cable by inserting to a module connector until a clicking sound comes.
Check any looseness after the loading. False connection may cause a mis-input
or mis-output.
Load a module by pressing against the DIN rail until a clicking sound comes.
Check any looseness after the loading. Improper installation may cause the
module to fall out, resulting in breakdowns.
Do not directly touch the module's conductive parts or electronic components.
Doing so could cause malfunction or trouble in the module.
[WIRING PRECAUTIONS]
Before beginning any installation or wiring work, make sure all phases of the
power supply have been obstructed from the outside.
Failure to completely shut off the power supply phases may cause electric shock
and /or damage to the module.
When turning on the power or operating the module after installation or wiring
work, be sure the module's terminal covers are correctly attached.
Failure to attach the terminal covers may result in electric shock.
When wiring the programmable controller, check the rated voltage and terminal
layout of the wiring, and make sure the wiring is done correctly. Connecting a
power supply that differs from the rated voltage or wiring it incorrectly may cause
fire or failure.
Tighten the terminal screws with the specified torque. If the terminal screws are
loose, it may result in short circuits, fire or malfunction. Tightening the screws too
far may cause damage to the screw and /or the module, resulting in short circuits,
fire or malfunction.
Be sure there are no foreign substances such as sawdust or wiring debris inside
the module. Such debris could cause fire, failure or malfunction.
Be sure to fix wires or cables leading from the module by placing them in the duct
or clamping them. Cables not placed in the duct or without clamping may hang or
shirt, allowing them to be accidentally pulled, which may result in a module
malfunction and cable damage.
Install our programmable controller in a control panel for use. Wire the main power
supply to the power supply module installed in a control panels through a
distribution terminal block.
Furthermore, the wining and replacement of a power supply module have to be
performed by a maintenance worker who acquainted with shook protection. (For
the wiring methods, refer to section 4.1)
