Wiring details and diagrams
Wiring - general
Terminal blocks for I/O and power supply are plug-in connectors with screw terminals. It is recommended to use ferrules on
wires.
LANs and LocalBuses are RJ45 - Note: Be careful to connect correctly. If a network interface cable is connected to a LocalBus
interface, the PC, switch, router or other network equipment will most likely be damaged.
COMs are 9 pole sub-D male connectors and RJ12 (RJ11) connectors.
The wiring diagrams cover all versions of the RTU32N variants. For RTU32N version without I/O this section is still relevant as
it include wiring details for supply voltage and comms interfaces.
Wire size
Earth and power supply: max. 2.5mm² (earth wiring must be 2.5mm² and kept as short as possible).
Other connectors: Max. 1.5mm² with ferrules.
