I/O Wiring
Applicable Wires
For power and input wiring, use AWG18 or AWG16 (0.75 to 1.25 mm
2
) solid or stranded wires. When connecting two
wires together, use wires of the same size.
Terminal Tightening Torque
Tighten the I/O terminals to a toque of 0.6 to 1.0 N·m. Also tighten unused I/O terminals.
Wire Termination
When using crimping terminals for wire termination, be sure to use an insulation tube on
the crimping terminal. One or two crimping terminals can be connected to one screw termi-
nal. Dimensions of an applicable crimping terminal are shown at right.
When wiring without using crimping terminals, strip the wire as long as the terminal clamp
plate (approx. 6 mm), and insert the wire until the wire insulation touches the end of the ter-
minal clamp plate.
Optional Jumper
When using the analog input module or Pt100 Ω input module, be sure to interconnect input terminals of each unused
channel using a wire or optional ring or spade type jumper. Otherwise an error may exceeds the rated value.
Grounding
The upper-right mounting hole has a FG terminal. Connect the FG terminal and control box as shown in the figure below.
Use a UL1007 AWG16 wire to connect the FG terminal to the ground (grounding resistance 100
Ω at the maximum).
The FG terminal is supplied with an M4 screw and
an embedded nut for ground connection when
mounting on a DIN rail. When mounting the SX5L
directly on a panel, prepare a proper screw for
grounding.
Remove paint from the panel surface for grounding
to make sure of electrical connection.
Warning
• Turn off the power to the SX5L before wiring the I/O and network cable. Failure to turn power off
may cause electrical shocks or fire hazard.
Caution
• Prevent metal fragments and pieces of wire from dropping inside the SX5L housing. Put a cover
on the SX5L module during wiring the I/O and network cable. Ingress of such fragments and
chips may cause fire hazard, damage, or malfunction.
• Run the power supply wiring as far away possible from motor lines to prevent malfunction.
• Use wires of an appropriate size to meet the voltage and current requirements. Using inappropri-
ate wires may cause overheat, resulting in possible fire hazard.
• Make sure of correct connection. Incorrect connection may cause overheat, resulting in possible
fire hazard.
• Do not run the I/O wiring in parallel with or in the vicinity of motor lines. Keep the I/O wiring
away from noise sources. Check for loose connection periodically. Loose connection may cause
overheat, resulting in possible fire hazard.
• Keep the power voltage and frequency within the rated values, otherwise the SX5L may be dam-
aged.
• Keep the input signal within the rated values, otherwise the SX5L may be damaged.
