Wiring Techniques

The wiring of FX

1S products has been designed to be safe and easy. If during the installation of these product or associated products concern is felt, please contact a professional electrician who is trained to the local and national standards applicable to the installation site.

Wiring Cautions

4.3

• 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.

Power Supply

When wiring AC supplies the “Live” cable should be connected to the “L” terminal and the

“Neutral” cable should be connected to the “N” terminal. Do NOT connect the “Live” wire to the

“N” terminal, the user might receive a dangerous shock on powerup.

Power Supply 4

Use a cable at least 0.2mm

(AWG24) to ground equipment. Ground resistance must be less than 100

Ω

(class D). Note that the ground cable must not be connected to the same ground as the power circuits. Grounding is recommended but if a proper ground cannot be provided the PLC will still operate correctly without being grounded.
