ND-123UJF / ND-130UJF
MECHANICAL INSTALLATION
Please review the descriptions below and drawings carefully; not
mounting the modules according to the described method may void
your warranty. Additionally, UL has tested and listed these modules for
mounting using bolts.
Mounting Using Frame Bolt Holes (Figure 10 & 11)
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 11 (back view
of the module) and Figure 10 (mounting detail). The module should be
fastened with four (4) M8 (5/16”) bolts. The mounting method is
designed to withstand loads of 2400 Pa. Take care during installation
to not block the drain holes (D) shown in Figure 11.

Under normal conditions, a PV module may produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values
of Isc and Voc marked on UL 1703 listed modules should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor
ampacities, fuse sizes and size of controls connected to the module output. Refer to Sec. 690-8 of the National Electric Code for an additional
multiplying factor of 125 percent (80 percent de-rating) which may be applicable. Where Canadian UL listing applies, installation shall be in
accordance with CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1.
