Requirements on the wiring loop area
For cables that transmit low‑level sensor signals and shared cables that transmit relay
signals, lay them close to each other to avoid large loop area. Use twisted pair cables
for analog signals. Lay digital signal cables close to each other.
Figure 8‑58 Recommended wiring loop area
Laying multiple types of cables
For cables of different types, route the cables along the equipotential metal plate. To
enhance the internal EMC performance, separate different types of cables or separate
cables with metal separators (recommended) in the same metal (zinc‑iron or stainless
steel) duct.
