How to Install
Don't underestimate the power of a tiny box! Photovoltaic junction boxes, often called solar junction boxes, are the unsung heroes of your solar energy system. These weatherproof enclosures, strategically placed on the back of each panel, play a critical role in ensuring safe, efficient, and long-lasting solar power generation. By housing and protecting the electrical connections between solar cells, junction boxes prevent exposure and potential damage. They also often contain bypass diodes that maintain energy flow even in shaded areas, maximizing your system's output.
Furthermore, some junction boxes offer surge protection, safeguarding your valuable solar investment from electrical spikes. For a reliable and high-performing solar power system, proper installation of photovoltaic junction boxes is a non-negotiable step.
Step 1
Strip the insulating layer of cable. L=7±0.3mm.Be attention and not to cut off the wire core.
Note: Please keep the cable cross section flat when cutting the cable.
Step 2
Put the stripped cable into the terminal hole and ensure that all cores are in the terminal hole.
Do not touch the positioning angle of the terminal
Step 3
Push the riveted pin into the insulator until they engage. Pull lightly on the lead to check that the metal part has engaged.
Step 4
Install the cable gland. First screw it by hands, then lock tightly by plastic spanner or plastic spanner and ring spanner. The front-end of connector need to be fixed during Production. Unscrew the rear cover, recommended input torque force 3.0N.m
Step 5
Insert male connector and female connector until they
engaged, which can verify whether the connector is in
place.
Note: Plug parts of the cable coupler together until they click in place. When connection is completed, the cable can be pulled to the left and right direction to confirm whether the connector is assembled well.
Step 6
The connectors can be unlocked by hands.
The cable of connector should not be bend too much, the minimum bending radius should be not more the four times of cable O.D generally . For accurate information , refer to cable manufacture’s specification.

Safety Measures
Safety
During your self- installation, if the used part and tool are not ruled by us or if you ignore our preparation and operation, we can't insure the safety and compatibility of the product technology of your self-installation.
Resistance
H07RN cables without tinned are not recommended. Cause the contact resistance of crimping place
will probably exceed the permitted value since the cooper wires are oxidized.
Electricity
For protecting against electric shock, please cut off the power when installing PV connector.
The final products must be supplied with the function electric shock proof.
Water-resistance
TL-CABLE01 are IP67 rated, and they can be positioned for half an hour under 1MT of water, But they can’t be put under water for long time.
Overload
In the case of the load, the connector is not allowed to be disconnected . In the case of it charging , it is not allowed to pull the plug.
Reactions
Some chemicals should avoid contacting with the connector body
