number, size and position of the grounding holes. The torque applied to ground fixation is 4N·m
~
8N·m.
接地孔设计在光伏组件背面的铝合金边框上,直径为
4mm
,使用单独的接地线和相关配件连接太阳能光伏组件
的铝合金边框并将接地线连接到大地,建议使用
M4*12mm
的接地螺栓并配套有
M4
的螺母,星型垫圈及平垫圈,这
样能确保组件被牢靠接地。您可以在组件产品手册上找到相应的产品图纸,来了解详细的产品接地孔数量,尺寸和
位置。接地固定应用扭力矩为
4N·m
~
8N·m
。
When grounding, each module can be grounded directly or in series or in parallel. If you choose the latter two
options, it is recommended that the maximum number of modules connected in parallel should not exceed four,
and in series should not exceed eight.
接地时,可以每块组件直接接地,也可以在组件串联或者并联后接地。在采取后者方式接地时,建议并联的最
大数量不应超过四块组件,串联的最大数量不超过八块组件。
In addition to use the grounding hole, you can also choose the following grounding ways:
除了使用接地孔来进行接地外,您也可以选用以下方式来进行接地:
(
1
)
Grounding by unused mounting holes
使用未被使用的安装孔接地
(

)
Other professional grounding devices
其他专用接地装置
The electrical contact points of all the above grounding methods should penetrate the anodized film of the
aluminum frame. PV modules can be grounded by other grounding devices, which must be reliable and certified.
The manufacturer's requirements should be followed.
不管采用哪一种接地方式,所有光伏组件铝合金边框的接地电接触点都需要穿透铝边框的阳极氧化涂层。在使
用专用接地装置等其他第三方的接地装置接地时,需要确保这些接地装置是可靠的,并且通过专业认证的产品,在
安装时需要遵守接地装置生产商的使用规定。
