Attentions
1.     The frequency of AC type pilot lamp is 50~60Hz.If work in other frequency ranges,it will be broken.
2.     The common threshold value of anti-interference pilot lamp is below 40V;and if you need higher threshold value please tell us.
3.     Connection error is not allowable to AC type dual-color light,otherwise pilot lamp will be broken.
4.     Avoid using welding mode to connect lines as possible and you should using general plug(2.5*0.8mm) to connect and wear the protective sleeve.If you need to weld,please finish it in 3 seconds by the electric iron which is below 30W and don't exert external force on terminals.
