4.1 Wiring cautions
Wiring cautions 4.1
• Do not run input signals in the same multicore cable as output signals or allow them to share the same wire.
• Do not lay I/O signal cables next to power cables or allow them to share the same trunking duct. Low voltage
cables should be reliably separated or insulated with regard to high voltage cabling.
• Where I/O signal lines are used over an extended distance consideration for voltage drop and noise interference
should be made.
• Do not lay signal cables near high voltage power cabling or cabinet housing along the same trunking duct. Effects
of noise or surge induction may occur. Keep signal cables of more than 100 mm (3.94") away from these power
cables.
• Cut off all phases from the power source before installation or performing wiring work to avoid electric shock.
Incorrect operation can lead to serious damage to the product.
• Cut off all phases from the power source before installing/removing extension or communication cables to modules
to avoid electric shock, incorrect operation or serious damage to the product.
• Replace the terminal cover provided, after installation or wiring work is completed, and before supplying power and
operating the unit to avoid electric shock.
• After reading the manual's safety instruction, initiate the operation for making program changes while the PLC is in
RUN mode, forcing ON/OFF, and switching RUN/STOP.
• The power supply of the extension units/blocks and the special function units/blocks should be started at the same
time or earlier than the FX
2N
Series main unit.
• DO NOT use the “
"
” terminal in PLC.
• When performing incorrect wiring or operation, serious damage will occur.
