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 2400 Pa.
(Figures 1 & 2)
Mounting Using Frame Bolt Holes
The modules may be fastened to a support using the bolt holes in
the bottom of the frames at location "C", as shown in Figure 1 (back
view of the module) and Figure 2 (mounting detail). The module
should be fastened with four (4) M8 bolts. Recommended torque is
12.5 Nm.
Mounting Using Clips on Long Edge of Module:
Long Edge Parallel to Array Rails (Figure 4)
The modules may be mounted using clips (clamps) designed for solar
modules as shown in Figures 3 and 4. Note that the clip positions are
important – the clip centerlines must be between 150mm 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
5mm and length of 38mm) as shown in Figure 3. 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 5)
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 5. The clip centerlines must be between 150mm
and 410mm from the ends of the module. Note that the mounting
clips should meet the minimum dimensions (catch width of 5mm and
length of 38mm) shown in Figure 3. 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
Conductor size: 4.0mm², 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-ContactAG (PV-KST4/PV-KBT4) as of 7thApril
2011. 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 (NU-R250J5 to
NU-R240J5, ND-R250A5 to ND-R225A5 and ND-R245A6 to
ND-R235A6), 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.
