Installation
1. Power off
Safety Warning: Please install and maintain the device by a professional electrician. To avoid electric shock hazard, do not operate any connection or contact the terminal connector while the device is powered on!
2. Wiring Instruction
The wiring diagrams illustrate the connections for the 1C, 2C, and 3C models. Ensure power is disconnected before wiring. The diagrams show connections for Live (L), Neutral (N), and the respective load outputs (L1 for 1C; L1, L2 for 2C; L1, L2, L3 for 3C).
Important: For electrical safety, it is essential to install a Miniature Circuit Breaker (MCB) or a Residual Current Operated Circuit Breaker (RCBO) with an electrical rating of 10A for the 1C and 2C models, and 6A for the 3C model, before the M5-120W. Ensure all wires are connected correctly.
3. Power on
After powering on, the device will enter Pairing Mode by default during the first use. The LED indicator will flash in a cycle of two short and one long flash. The device will exit Pairing Mode if not paired within 10 minutes. To re-enter pairing mode, press and hold the button for 5 seconds until the LED indicator flashes in the specified pattern.
