5.2.2 GROUNDING
接地（
Apply to Framed Duomax
适用边框双玻组件）
Duomax without frame do not need grounding because there will be no leakage
current between cell and encapsulation material due to non-frame structure
双玻组件没有边框，不会形成电池和封装材料间的漏电流，因此无需接地处理。
All module frames and mounting racks must be properly grounded in
accordance with appropriate respective National Electrical Code.
所有组件边框和安装架必须按照相应的《国家电气规程》正确接地。
Proper grounding is achieved by bonding the module frame(s) and all metallic
structural members together continuously using a suitable grounding conductor.
The grounding conductor or strap may be copper, copper alloy, or any other
material acceptable for use as an electrical conductor per respective National
Electrical Codes. The grounding conductor must then make a connection to
earth using a suitable earth ground electrode.
通过使用合适的接地导体将组件边框和所有金属结构件连续连接在一起以实现正
确接地。接地导体或接地线可以是铜、铜合金或任何其他符合相应的《国家电气
规程》要求的用作电导体的材料。接地导体必须通过合适的接地电极连接到大
地。
Trina Solar modules can be installed with the use of third party listed grounding
devices for grounding the metallic frames of PV modules. The devices have to
be installed in accordance with the grounding device manufacturer’s specified
instructions.
天合光能的太阳能组件可以使用第三方列出的接地装置对
PV
组件的金属边框进行
接地安装。设备必须按照接地设备制造商的指定说明进行安装。

Grounding hardware comes in a package that includes the grounding screw, flat
washer
、
star washer and wire
套装附带有接地硬件，其中包括接地螺丝、平垫圈、星形垫圈、链接导线。
Electrical contact is made by penetrating the anodized coating of the aluminum
frame, and tightening the mounting screw (come with the star washer) to the
proper torque of 25lbf.in.
电接触点是通过穿透铝边框的阳极氧化涂层并拧紧接地螺丝（与星形垫圈一起）
至
25lbf.in
的适当扭矩形成的。
Grounding wire size (6 to 12 AWG solid bare copper) should be selected and
installed underneath the wire binding bolt.
应选择合适尺寸的接地线（按照美国线规
6
至
12
的实心裸铜线）并将其安装固定
在连接螺栓下面。
