Shelly 1PM Gen3 module connection diagram
Before connecting the Shelly 1PM module, turn off the power supply in the circuit in which it will be installed. Make sure that the device is located in a safe place, protected from the weather and inaccessible to unauthorized persons.
The module is equipped with six screw connectors to which you can connect the wires using a screwdriver. Here is a description of the individual connectors:
- O : potential-free output
- L1 / L : 230 V AC power supply (or 24 V to 30 V DC), positive pole
- SW : switch input that controls output O
- Debug port : used for diagnostics and testing of the module
Always remember to exercise caution when working with electrical equipment.
