Separate the control circuits that supply power to the mainUnit from the main circuits using dedicated circuit protectors and fuses.3-1-2 Power Supply Voltage! CautionUse the power supply voltages indicated in Section 2 Unit Specifications andComponents. Failure to adhere to the specifications may result in fire.If the power supply voltage falls below 85% of the rated voltage, the CPM2A willstop and all outputs will be turned OFF.
If low voltage affects the equipment, etc.,provide a protection circuit which shuts off the output until the supply voltage returns to the rated value.In places where power supply conditions are poor, take steps to ensure thatpower is supplied at the rated voltage. Be sure to adhere to safety precautions,such as providing breakers to prevent short circuits in external wiring.When conducting any of the following operations, turn OFF the power to the PC.Electrocution, product damage and malfunction may result.• Connecting or disconnecting Expansion Units, Expansion I/O Units, and CPUUnits.• Assembling Units• Connecting cables and wiring.3-1-3 Interlock and Limit Circuits! WARNING Emergency stop circuits, interlock circuits, limit circuits, and similar safetymeasures must be provided in external control circuits (i.e., not in theProgrammable Controller) to ensure safety in the system if an abnormalityoccurs due to malfunction of the PC or another external factor affecting the PCoperation.
