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 2,400 Pa.
Mounting Using Frame Bolt Holes (Figures 1 & 2)
The modules may be fastened to a support using the bolt holes in the bottom of the frame 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 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 150 mm and 410 mm 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 10 mm. Note that the mounting clips should meet the minimum dimensions (catch width of 5 mm and length of 38 mm) 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).
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 150 mm and 410 mm from the ends of the module. Note that the mounting clips should meet the minimum dimensions (catch width of
5 mm and length of 38 mm) shown in Figure 3. The array rails must support the bottom of the modules and must be continuous pieces (no breaks in the rail).
2. ELECTRICAL INSTALLATION INSTRUCTION
Cable characteristics
Conductor size: 4.0 mm
2 , Cable type: XLPE cable (CE cable), Maximum DC voltage: 1.8 kV, Ambient temperature: –40 °C to +90 °C, Maximum conductor tem-
perature: 120 °C
Module configuration (Recommend)
# Maximum series configuration: please refer to Table 1 (This value is calculated under the condition of V
oc 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 7th April 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 Terminal box). For PV modules with anti-reflective coating glass (ND-R250A5 to ND-R220A5,
NU-R250J5 to NU-R240J5), 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.
