1、在完成灯具安装时可触及的，并且绝缘失效时能变为带电的部件；

1, when to complete the installation of lamps and lanterns palpable, and insulation failure can become electrically charged components; 

2、为灯具清洁而打开时可触及的，并且绝绿失效时可能变为带电的部件；

2, when open the palpable for clean lamps and lanterns, and absolutely green fails may become electrically charged components; 

3、灯具中安全部件所在的金属安装面；

3, lamps and lanterns of the safety components of metal mounting surface; 

4、与灯具中的安全部件(如电线、控制装置)接触的或可能接触的金属表面；

4, with lamps and lanterns of security components (such as electrical wiring, control equipment) or may contact the metal surface; 

5、更重要的是要从结构上去保证它们之间的连续性。

5, what is more important to went up from the structure to ensure the continuity between them. 

6、用黄绿双色线作标识的导体,无论是内部接线还是外部接线,应仅与接地端子连接；

6, with the yellow green double color line for identification of conductor, whether internal or external wiring connection, should be connected to the earthing terminal only; 

7、用自攻螺丝钉可用来保护接地的连续性，只要在正常使用时不会妨碍这种连接，并且每一连接处至少用两只螺钉；

7, with self tapping screws can be used to protect the grounding continuity, as long as in this connection will not interfere with the normal use, and each joint with at least two screws; 

8、用铝和铜不可直接连接接地，会起电化学反应造成接触电阻变大，影响接地连续的低电阻性；

8, with aluminum and copper cannot be directly connected to ground to electrochemical reaction will cause the contact resistance, impact grounding continuous low resistance; 

9、接地电阻的测量，可用测量设备调至 12V，10A 检测，电阻值≤0.5欧。

9, the grounding resistance measurement, measuring equipment is available to the 12 v, 10 a detection, resistance or less 0.5 euro.
