Picture 5. Connect connectors
9) If the connectors need to be disconnected, installer should use the exclusive tool to disconnect them
after safety measure such as cut-off of connection band.
10) Connected cables and connectors should be fixed.
11) Action against contamination or corrosion should be enacted on disconnected connectors.
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.
5.8 Diode
When there is partial shade on a PV module, reverse-voltage can
occur
inside PV module. In order to
protect this phenomenon, the diodes are normally installed in the Junction Box. HES PV modules are
equipped with bypass diodes. If installer wishes to change into other diodes, the installer should inform
an authorized engineer of HES.
