(4) The Sunceram II cells for outdoor use are provided
with leads or solder electrodes on the rear, and these
protrude. Grooves or holes should be provided in the
area of the product where the cells are to be secured.
The cells should be fastened in such a way that the
leads or solder electrodes will not be brought into
close contact with the fastening parts, thereby
preventing distortion or deformation.

3 Condensation
Condensation may form when the Sunceram II cells for
outdoor use are encased and assembled into a product.
Droplets of water from condensation on the cover may
corrode the Sunceram II cell electrodes and other parts.
These droplets can be eliminated for the most part by
making an small hole in the circumference of the cells'
fastening parts as shown in the figure below.

4 Covering the cell surfaces
Directly covering the top and/or bottom surfaces of the
Sunceram II cells for outdoor use with PVC or some
other transparent film will impair the performance of the
cells.
3.7.3. General precautions
(1) The Sunceram II cells for indoor use employ glass
for the substrate and could result in injury. Licking
the cells or putting them in your mouth is dangerous
and should not be done.
(2) Do not drop Sunceram II cells for outdoor use from
high places or subject them to a strong impact. They
may suffer damage or their performance may be
impaired.
(3) Since the electricity is generated by the irradiation
of light from the light-sensing side (glass surface),
do not make this surface dirty with oil or other
substances. If this surface becomes dirty, wipe off
the dirt before use.
(4) The rear surface of the Sunceram II cells for outdoor
use is coated with resin for protection. Bear in mind
that wiping this surface with a cloth moistened with
paint thinner or some similar substance will wear
away the resin and, in severe cases, this may result
in impaired performance.
(5) Do not make marks or scratches with a knife or
other pointed object since the rear side of the
Sunceram II cells for outdoor use is soft and the
cells themselves are formed with a thin film several
dozen micrometers thick. Marks and scratches may
damage the exterior and impair the performance.
(6) Do not pull the leads with a force exceeding that
required. Damage may occur as a result.
(7) See Notice to Readers (on the back cover).
3.7.4. Storage precautions
Normal storage does not entail any special requirements.
Avoid storage in extremely high (over 70°C) or
extremely low (under -20°C) temperatures for long term.
Also avoid storage in places where both the temperature
and humidity are high (over 60°C and over 80% RH).
