Installation
Compatible SONOFF Gateways
Before adding a device, please upgrade the gateway firmware to the latest version.Other compatible SONOFF gateway models: ZBDongle-P, ZBDongle-E
1. Power off
WARNINGPlease install and maintain the device by a professional electrician. To avoid electric shock hazards, do not operate any connection or contact the terminal connector while the device is powered on!
2. Wiring instruction
To ensure the safety of your electrical installation, it’s essential either a Miniature Circuit Breaker (MCB) or a Residual Current operated Cicuit-breaker with Integral Overcurrent protection(RCBO) with an electrical rating of 10A has been installed before the ZBM5-1C-120W, ZBM5-2C-120W, ZBM5-3C-120W.
No neutral required mode wiring：
Neutral required mode wiring：
● In no neutral required mode: the minimum supported load is 3W, and this device does not support other types of inductive loads such as fans.
● Make sure all wires are connected correctly.

3. Power on
After powering on, the device will enter the pairing mode defaulted during the first use and the LED signal indicator will “flash slowly”.
It takes 10 seconds for the device to work normally after being powered on for the first time.
*The device will exit the pairing mode if you do not operate it within 3mins. When you want to enter the pairing mode again, long press the any button on the device for 5 seconds until the signal light “flashes slowly” and release.
