GENERAL INSTALLATION MANUAL
PV MODULES: P/M SERIES
8. INSTALLATION
Refer to the installation of individual models
of PV module in this manual.
9. ELECTRICAL RATINGS
Refer to the mechanical and electrical ratings
of individual models of PV module in the an-
nex of this manual.
10. GROUNDING
■
Each PV module has two grounding holes
on each short side frame. Do not drill ad-
ditional grounding holes on the frame. And
the negative pole of the modules must be
grounded also. Otherwise, the module
warranty will be void.
■
The grounding is considered within the re-
quirement of local regulation at the site of
installation.
■
When needed frame grounding, please
refer to below example of connection.
Figure 2 - SERIES for more voltage
Figure 3 - PARALLEL for more current
Please be careful in arranging the system
ground so that the removal of one module
from the circuit will not interrupt the groun-
ding of any other modules. The modules
should be grounded to the same electrical
point.
■
An example of acceptable ground connec-
tion using a screw, nut (hardware not
provided) and washer retaining a ground
screw is shown in figure 4. The size of the
grounding cable should be decided by the
professional person who responsible for
electrical installation. In a connection of
this type, the hardware (such as a toothed
locked washer / star washer) must score
the frame surface to make positive elec-
trical contact with the frame. The ground
wire must be considered within the requi-
rement of local and regulation at the site
of installation.
■
If steel parts used for grounding purpo-
se, steel parts must be plated, painted or
enameled for protection against corrosion
before usage.
