Pre-installation
With the incidence of sunlight on all photovoltaic modules, a voltage appears at the
output terminals of the photovoltaic module turning it into a live power source. To
avoid a shock hazard make sure the solar module is covered with an opaque (dark)
material such as paper / cloth.
Stainless Steel can be subject to a process called “thread galling” in which bolts can twist
off and/or the bolt threads seize to the nut’s thread. Apply anti-galling lubricant avail-
able at most hardware or auto-parts stores to all the stainless steel fasteners before in-
stallation. If anti-galling lubricant is not available, any standard lubricant will minimize
the occurrence of “thread galling”.
Well Nut For Anchoring 28" Base Support Mounting
Rails To The RV Roof Or Flat Surface
A Well-Nut is a bushing of tough neoprene rubber with a fl ange at the top end and a
captive brass nut mounted within the bore at the bottom end (Fig. 2). This is used to
anchor the 28" base support mounting rails (1, 2 of Fig.1) on to the roof of the RV or to
other fl at surface. Typical installation is shown in Figs 3 to 6. Tightening a conventional
machine bolt or screw engages the captive nut thereby causing the bushing to expand
outwards. This fastens securely to thinner RV roofs by bulging up and against the bot-
tom surface of the roof (Fig. 5). If used in a blind hole in a solid surface material, the
rubber will expand outwards to create a secure fastening (Fig. 6). The neoprene and
brass resist most environmental conditions. Additionally, the Well-Nut seals the drilled
hole effectively against air and liquid leakage.
