Installation And Maintenance

1.DIN 35MM standard rail installation

2.The product adopt the flame - retardant ABS housing,fix the products,connect the power lines and ground lines,examine and power up.

3.Grounding is very important to the normal work of SPD.the ground contact area is no less than 25 mm2 and as short as possible.

4.the products don't need special maintenance while it is on position for a long time.So we should assign some people to examine regularly.Especially in The thunderstorm season.Once stuck,check it Immediately.

5.The product is equipped with a fault indicator.when working correctly,the indicator shows green,When this system malfunctions,it shows red.

6.The internal components is with alternating current,be careful when the system is working.
