Grounding of the module frame can be achieved through use of clamps that penetrate the
anodization in conjunction with grounding of the mounting system or through direct
grounding of the frames by attaching a copper wire to a grounding hole of each module (bolt
size, M6 × 1.0 × 50).

Both standards apply to all module series described in this manual, however, a cable with a
suitable cross section must be used for conducting the sum of the currents as generated by
the modules. A series protection fuse of 15A is recommended for each string when module
strings are wired in parallel.
BenQ Solar recommends the PV conductor, which cross section is 4 mm
2
. External
connection boxes can be used to enable greater cable cross section area for long distance
transmission.
The modules are qualified for the application class A: Hazardous voltage (IEC 61730: higher
than 50V; EN 61730: higher than 120V), hazardous power applications (higher than 240W)
where general contact access is anticipated.
