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 HHI.
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 (See the picture 12).
1) Protection Degree : IP65
2) Temperature Range : -40°C ~ +85°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 R
≥
5 x cable diameter must be maintained. The cable must be routed in a way that tensile
stress on the conductor or connections is prevented.

5.7 Conduit
For conduit application, it is necessary to follow the regulation for outdoor installation of conduit. All
fixing parts should be protected from any damage and moisture.
6. Diodes
When there is partial shade on a PV module, reverse-voltage can circulate inside PV module. In order
to protect this phenomenon, the diodes are normally installed in a Junction Box. HHI PV modules are
equipped with bypass diodes. If installer wishes to apply additional diode, he or she should inform an
authorized engineer of HHI.
