1. INSTALLATION
The mounting method has been verified by SHARP and NOT
CERTIFIED by a third party organization. Please review the
descriptions and drawings carefully; not mounting the modules
according to one of these methods may void your guaranty.
These mounting methods are designed to allow module
loading of 2400Pa.
Mounting Using Clips on Long Edge of Module:
Long Edge Parallel to Array Rails (Figure 2)
The modules may be mounted using clips (clamps) designed
for solar modules as shown in Figures 1 and 2. Note that the
clip positions are important – the clip centerlines must be
between 205mm and 410mm from the end of the module.
The module must be supported along the length of the long
edge, and should overlap the array rail by at least 10mm. Note
that the mounting clips should meet the minimum dimensions
(catch width of 7mm and length of 38mm) as shown in Figure
1. The array rails must support the bottom of the frames and
must be continuous pieces (no breaks in the rail). The module
is recommended to be fastened with stainless steel M8 bolts
with torque of 16 Nm.
Mounting Using Clips on Long Edge of Module:
Long Edge Perpendicular to Array Rails (Figure 3)
The modules may also be mounted using clips on the long
sides of the module when the array rails are perpendicular to
the long sides, as shown in Figure 3. The clip centerlines must
be between 205mm and 410mm from the ends of the module.
Note that the mounting clips should meet the minimum
dimensions (catch width of 7mm and length of 38mm) shown
in Figure 1. The array rails must support the bottom of the
frames and must be continuous pieces (no breaks in the rail).
The module is recommended to be fastened with stainless
steel M8 bolts with torque of 16 Nm.
2. ELECTRICAL INSTALLATION INSTRUCTION
Cable characteristics
2
Conductor size: 4.0mm
, Cable type: XLPE cable (CE cable)
Maximum DC voltage: 1.8kV
Ambient temperature: -40°C to +90°C,
Maximum conductor temperature: 120 °C
Module configuration (Recommend)
# Maximum series configuration: please refer to Table 1
(This value is calculated under the condition of Voc at
40 °C.)
# Maximum parallel configuration: (Parallel connection of each
string shall be conducted with following two options. Any other
parallel connections are prohibited.)
a) Case of using the diodes; 1 diode per maximum 2 parallel
strings (Connect a diode or more in series for every string or
every 2 parallel strings for protection of module from reverse
current over load.)
b) Case of using the fuses; 1 fuse per every string (Connect a
fuse for every single string for protection of module from
reverse current over load.)
Connection cables requirement
The module is fitted with SMK Corporation connectors
(CCT9901-2451F/CCT9901-2361F) which are mechanically
and electrically compatible with Multi-Contact AG (PV-
KST4/PV-KBT4) as of 23 October 2013. To extend the module
connecting leads, only use Multi-Contact AG (PV-KST4/PV-
KBT4), or SMK Corporation connectors under the same series.

3. WARNING
Do not stand or step on the PV module (Glass, Frame, Film
and Junction box).
For PV modules with anti-reflective coating glass, do not touch
the glass since finger prints or stains will easily mark the glass.
If dirt build-up becomes excessive, clean the glass surface
with water only.
