WARNING
Caution
I/O Configuration
Only basic insulation is provided for the control circuit terminals. Additional
insulation may be necessary in the end product.
These circuits are not separated from hazardous circuits by protective
separation, but only with basic insulation. These circuits cannot be accessed
and must not be interconnected with any circuits which are accessible, unless
they are isolated from accessible circuits by supplemental insulation. These
circuits can be connected only to the following circuits:
30 VDC or less (overvoltage category 2)
250 VAC or less (overvoltage category 2)
Wire inputs and outputs to the 3G3MV-P10CDT Unit as shown in the f
ing diagrams.
The PLC outputs may remain ON or OFF due to deposits on or burning of the
output relay or destruction of the output transistors. External safety measures
must be provided to ensure safety in the system. Not providing proper safety
measures may result in serious accidents.
Note When equipment must conform to the EC Directives (Low-voltage Direc-
tives), use a power supply with double insulation or reinforced insulation.
Check that wiring has been performed correctly before supplying power.
Supplying power with incorrect wiring may result in damage to internal circuits.
The following diagrams show the I/O configurations.
