[Design Precautions]

zWhen a safety programmable controller detects an error in an external power

supply or a failure in programmable controller main module, it turns off all the

outputs. Create an external circuit to securely stop the power of hazard by

turning off the outputs.Incorrect configuration may result in an accident.

zCreate short current protection for a safety relay, and a protection circuit such

as a fuse, and breaker, outside a safety programmable controller.

zWhen data/program change, or status control is performed from a PC to a

running safety programmable controller, create an interlock circuit outside the

sequence program and safety programmable controller to ensure that the

whole system always operates safely.

For the operations to a safety programmable controller, pay full attention to

safety by reading the relevant manuals carefully, and establishing the

operating procedure.

Furthermore, for the online operations performed from a PC to a safety CPU

module, the corrective actions against a communication error due to a cable

connection fault, etc. should be predetermined as a system.

zAll output signals from a safety CPU module to the CC-Link Safety system

master module are prohibited to use. These signals can be found in the

CC-Link Safety System Master Module User's Manual.

Do not turn ON or OFF these signals by sequence program, since turning ON/

OFF these output signals of the programmable controller system may cause

malfunctions and safety operation cannot be guaranteed.

zWhen a safety remote I/O module has detected CC-Link Safety error, it turns

off all the outputs. Note that the outputs in a sequence program are not

automatically turned off. If CC-Link Safety error has been detected, create a

sequence program that turns off the outputs in the program. If the CC-Link

Safety is restored with the outputs on, it may suddenly operate and result in

an accident.

zTo inhibit restart without manual operation after safety function was performed

and outputs were turned OFF, create an interlock program which uses a reset

button for restart.

[Installation Precautions]

zDo not bunch the wires of external devices or communication cables together

with the main circuit or power lines, or install them close to each other.

They should be installed 100 mm (3.94 inch) or more from each other.

Not doing so could result in noise that would cause malfunctions.

zUse a safety programmable controller in the environment that meets the

general specifications described in this manual.

Using this programmable controller in an environment outside the range of the

general specifications could result in electric shock, fire, erroneous operation,

and damage to or deterioration of the product.

zWhile pressing the installation lever located at the bottom of module, insert the

module fixing tab into the fixing hole in the base unit until it stops. Then,

securely mount the module with the fixing hole as a supporting point.

Incorrect loading of the module can cause a failure or drop.

Secure the module to the base unit with screws.

Tighten the screw in the specified torque range.

If the screws are too loose, it may cause a drop of the screw or module.

Over tightening may cause a drop due to the damage of the screw or module.

zCompletely turn off the external supply power used in the system before

mounting or removing the module.

Not doing so could result in damage to the product.

zDo not directly touch the module's conductive parts or electronic components.

Doing so may cause malfunctions or a failure.

Not doing so could result in electric shock or malfunctions.

zUse a solderless terminal with insulation sleeve for wiring of a terminal block.

Use up to two solderless terminals for a single terminal.

zUse applicable solderless terminals and tighten them with the specified

torque.

If any solderless spade terminal is used, it may be disconnected when the

terminal screw comes loose, resulting in a failure.

zWire the module correctly after confirming the rated voltage and terminal

layout.

Connecting a power supply of a different rated voltage or incorrect wiring may

cause a fire or failure.

zTighten a terminal block mounting screw, terminal screw, and module

mounting screw within the specified torque range.

If the terminal block mounting screw or terminal screw is too loose, it may

cause a short circuit, fire, or malfunctions.

If too tight, it may damage the screw and/or the module, resulting in a drop of

the screw or module, a short circuit or malfunctions.
