General Precautions When Wiring the Input/Output Signal Wires
WARNING
• To prevent the possibility of electric shock when wiring, confirm that the
power supply source and the signal source are turned OFF. After making the
connections, secure the terminal cover and do not touch the terminals with your
hands.
• For signal wires on which voltage exceeding 30 VAC/60 VDC is applied relative
to the ground potential or between signals, use double (reinforced) insulation
wires. For all other signal wires, use basic insulation wires. For the withstand
voltage of insulation wires, see the table below.
Applied Voltage (Vrms or VDC) Basic Insulation Double (reinforced) Insulation
0 to 150 1350 Vrms 2700 Vrms
151 to 300 1500 Vrms 3000 Vrms
301 to 600 2210 Vrms 3700 Vrms
• To avoid electric shock when removing the screw terminal block and screw
terminal plate, be sure to attach the screw terminal block and screw terminal
plate to the input modules before inputting signals. Electric shock or fire can
result if signals are applied to the terminals when the screw terminal block or
screw terminal plate is removed from the input modules.
• When wiring to screw terminals, use round, insulation coated crimp-on lugs on
the terminals (4-mm screws on the screw terminal block, and 3-mm screws on
the screw terminals and screw terminal plate) that do not come out when loose.
• To prevent fire, use signal wires of the following temperature ratings.
Module Type Temp. Rating
Screw terminal block 75°C
Universal input module, DCV/TC/DI input module, 4-wire RTD
resistance input module, Strain input module, Pulse input module,
Digital input module, Digital output module
80°C
Analog output module, PWM output module 85°C
