Notices :
1. The AC input earth-plating must connect to the real protective grounding line, not connect to neutral line or far grounding line in order to improve the thunder proof and anti-jamming function.
2. Make sure the right polarity when connect the battery.
3. There must allow over 100mm space in front of the power and home front of the power when installation in order to make sure it vents well .
4.The operating environment must pay attention to dustproof, dampproof, far form heat source and electromagnetism interference,no causticity gas and metal dust. If can not confirm the good environment , you must clear the dust ,sundries in certain time in order to assure it is vents well and the reliability.
