5.5 Module Terminations
The installer should connect cables using the same cable connector equipped in each PV module. For
more information about electrical connection, contact an authorized engineer of HES. HES does not
give warranty for the case of using connectors which are not approved by HES.
5.6 Junction Box & Terminals
A PV module has the plus and minus connectors and a junction box with bypass diodes. On the
junction box, the polarity is clearly marked.
1) Protection Degree : IP67
2) Temperature Range : -40°C ~ +90°C
3) Wire Size : 4.0mm

4) The cable must not be bent or crushed on the direct exit of the cable screw joint. A minimum bending
radius 43mm must be maintained. The cable must be routed in a way that tensile stress on the
conductor or connections is prevented. (Picture 4)

5) When connect connectors, insert connector until locking hook catches the holder and clicks. Pull
each connector gently and make sure connectors are not disconnected. (Picture 5)
6) Do not give between the connector and cable a strong pull (over 10kg).
7) Do not apply external stress to the body of connector. Do not place the connectors in water.
8) When same series modules with different connectors are installed together, make sure those two
connectors are compatible.
