4.5 Precautions on Construction and Wiring
1. During the wiring of FBS–PLC, please follow local national standards or regulations for installation
2. Please choose the wires with proper wire gauge for I/O wiring according to the current loads.
3. Shorter wires are preferred. It is advised that the length of I/O wiring does not exceed 100m (10m for high-speed
input).
4. Input wiring should be separated from output or power wiring (at least 30~50mm apart). In case separation is not
possible, adopt vertical crossing, no parallel wiring is allow.
5. The pitch of FB
