Characteristics; Power Supplying To The Plc - LG MASTER-K10S1 User Manual

■ ■ ■ ■ Characteristics
• The user program is stored in a EEPROM, and no battery back-up is required.
• Data communication through RS232C and RS485 is available.
• K10S1 includes a high speed counter being applicable for a simple positioning system.
• K10S1 series are suitable for the control of small machinery having I/O points
less than 14 .
■ ■ ■ ■ Power Supplying to the PLC
• To prevent the PLC from an improper
operation caused by the external noise,
place a insulation transformer and/or a
noise filter as shown in the right figure.
• Always install AC power cable and
signal or data lines in separate ducts or
bunches.
• The fuse in the DC power supply may be blown when the DC power
is supplied in reverse polarity.
• Be careful to connect power source cable to the correct terminal.
Internal device of PLC may be damaged by the improper lead connections.
• Supplying power beyond rated voltage/frequency may damage internal devices.
• Grounding
