Safety Precautions
After you perform safety validation, check items for safety validation printed out to con-
firm Safety Control Units are correctly configured.
Although the Simulator and Simple Automatic Test simulate the operation of the Safety
CPU Unit, there are differences from the Safety CPU Unit in operation and timing. Al-
ways confirm operation on the actual equipment before you operate the equipment.
Accidents may occur if the controlled system performs unexpected operation.
Wiring
Wire the safety input and output lines so that they do not touch other lines.
Serious injury may possibly occur due to loss of required safety functions.
Wire the Safety Control Unit properly so that 24-VDC lines do not touch output lines
accidentally or unintentionally.
Serious injury may possibly occur due to loss of required safety functions.
Wire the safety output lines and 24-VDC lines so that ground faults will not cause the
loads to turn ON.
Serious injury may possibly occur due to loss of required safety functions.
The wiring information that is displayed on the Sysmac Studio is for reference only and
may differ from the actual wiring diagrams. Always confirm the actual wiring and per-
forming suitable wiring.
Serious injury may possibly occur due to loss of required safety functions.
During Power Supply
Do not touch any of the terminals or terminal blocks while the power is being supplied.
Doing so may result in electric shock.
Do not attempt to take any Unit apart.
In particular, high-voltage parts are present in Units that supply power while power is supplied or
immediately after power is turned OFF. Touching any of these parts may result in electric shock.
There are sharp parts inside the Unit that may cause injury.
Replacing Units
When replacing a Safety Control Unit, confirm that the model of the Unit is correct,
confirm that the Unit and terminal block mounting positions are correct, configure the
replacement Unit suitably, and confirm that the Unit operates correctly.
Voltage and Current Inputs
Make sure that the voltages and currents that are input to the Units and slaves are
within the specified ranges.
Inputting voltages or currents that are outside of the specified ranges may cause acci-
dents or fire.
