6-1 Precaution for wiring
Follow the below instructions for wiring:
1. Separate power line and I/O lines of the JW300 from high voltage lines and power lines as far as
possible. Do not run power lines and I/O lines in parallel with high voltage or power lines.
2. For the I/O expansion cable and wiring the 5 VDC lines, use supplied accessories for the I/O
expansion cable.
3. Don't run the I/O expansion cable and the 5 VDC cable inside a duct.
4. Provide easy-to-detach wiring thoroughly considering operability at maintenance and repair.
5. Use twisted cables of over KIV 1.25 square for connection to the primary power input terminal of
the power supply module.
6. Use cables of over KIV 0.5 square (0.18 square/32 points connector type) for wiring from the relay
terminal block of the control panel to the input module. For wiring to the output module, use cables
of over KIV 0.75 square for large capacity such as solenoid valves; and cables of over KIV 0.5
square (0.18 square/32 points connector type), for other usage.
7. Use wires of over KIV 1.25 square for wiring from the relay terminal block to input/output equipment.
8. When the whole factory site is grounded for high electricity and not suitable for the grounding of
the JW300, connect the GND terminal of the JW300 with just the board ground.
9. Use the crimp-style terminals of our recommendation for wiring to the terminal blocks of the
JW300, whenever possible.
