SAFETY PRECAUTIONS
1. The device must be installed by a qualified person,
2. Disconnect all power before working on the device. Don’t touch any terminal
when the power is ON.
3. Verify correct terminal connection when wiring.
4. Don’t dismantle or repair the device whether it operates normally, otherwise
no responsibility is assumed by producer and seller.
5. Never use the device at the site which can be invaded by corrode gas, strong
sunshine light and rain.
6. Clean the device with a dry cloth.
7. Fail to follow these instructions will result in serious injury or death.
