afety precautions:

a)   When the solar photovoltaic SPD is installed in final system, it must achieve all the requirements of GB4943 (EN60950, IEC60950) standard;

b)   The equipment has to be installed by authorized professional person, before installation, to cut off power supply, and prohibit hot-line work from accidents

 

Application

AM type DC photovoltaic series power SPD is often used to prevent over-voltage and transient over-voltage from damaging DC power system and equipments, especially in photovoltaic solar power system.

 

Features:

1)  Temperature control circuit break technology, built-in over-current protection circuit, to completely keep away from fire disaster

2)  International famous components and advanced manufacturing technique

3)  Big discharger current capacity, low residual voltage

4)  Remote alarm connect point (optional)  

5)  Clear and intuitive working condition

6)  Easy installation and maintain

7)  Exquisite process, can work under the hostile environment for a long time, like acid, alkali, dust, salt fog, wet, etc

Installation

1)  35mm slide guide installation way

2)  Connect +/- and ground terminal of power system to +/- and ground terminal of SPD, then screw up the bolts

3)  ground line of SPD to lightning protection system ground device

4)  After wiring, please check it until everything is going well, to put into operation.

 

Product maintenance

a) The equipment has to be installed by authorized professional person, before installation, to cut off power supply, and prohibit hot-line work from accidents

b) The sectional area of wire must reach technical demands

c)  When the SPD box is installed in final system, it must achieve all the requirements of GB4943 (EN60950, IEC60950) standard;

d) The product does not need to be maintained specially, but to inspect at fixed period

e)  After thunderstorm season, it is normal that the indicator window is red, but to change a new module or total product instantly

f)  Once there is a failure during system operation, please remove the SPD device at first, if the system can operate normally, the device is broken
