ELECTRICAL WORK
If you want to use the connector purchased by yourself, the following requirements must be complied:
Use only connector special designed for solar electric systems.
Use the recommended or specified tools when install the connectors.
Do not unplug the connectors when the power is on.
The connector suitable for the solar photovoltaic system can be obtained from the manufacturer.
Electrical connection:
Completely cover the module with an opaque material during mechanical installation and electrical
Installation.
Protect the cables from being damaged.
Ground mounting must abide with all local regulations.
Storage battery can not be connected with the solar photovoltaic system.
Grounding:
The module frame must be properly grounded. The grounding wire must be properly fastened to
the module frame to assure good electrical contact.
If the support frame is made of metal, the surface of the frame must be electroplated and have
excellent conductivity. The grounding wire must be properly fastened to the support frame .
There are two pre-drilled mounting holes in the frame, used to install the grounding cable. Each
module should connect with the grounding cable.
We recommend the closed lug when grounding. First insert the ground cable into the jack of the
closed lug, then insert the stainless steel bolt (M3) into the tab of the lug, the grounding
hole on the frame and finally a nut to secure the entire assembly. The spring washer is required in
order to prevent screw loosening and cause improper grounding.
The grounding resistance must be less than 10 ohms.

Junction box installation:
All modules come with a permanently attached junction box and provide with fitted cables.
The junction box is part of the panel itself, please contact the manufacturer if there is
any problem with the module.
