4. Setup and Installation
4.1 Pre-installation Checklist
- Ensure you have a compatible Z-Wave gateway (hub) for device pairing and control.
- Verify that the electrical circuit is rated for the device's specifications.
- Gather necessary tools: screwdriver, wire strippers, voltage tester.
4.2 Wiring Instructions
WARNING: Disconnect power at the circuit breaker before proceeding.
- Connect the Neutral (N) wire from your electrical supply to the 'N' terminal on the Shelly Wave 2PM.
- Connect the Live (L) wire from your electrical supply to the 'L' terminal on the Shelly Wave 2PM.
- Connect the load (e.g., light fixture, appliance) for the first channel to the Output 1 (O1) terminal. The other side of the load should be connected to Neutral.
- Connect the load for the second channel to the Output 2 (O2) terminal. The other side of the load should be connected to Neutral.
- If using external switches for manual control, connect the switch wires to SW1 and SW2 terminals. These switches should be connected to the Live (L) line.
4.3 Physical Installation
