SUNCERAM II CELLS FOR INDOOR USE - CONTINUED
2.7. Precautions for use
[Adhere strictly to the guidelines below since mishandling the cells may impair their performance.]
2.7.1. Handling precautions when installing cells in equipment
The method of installing the Sunceram II cells for
indoor use in a product is selected by the construction of
the output terminal areas as shown in the table below.

(C type)
* Copper electrode: type is designated by the suffix not added to the model number "C".
Standard units come with copper electrodes.
* When the output terminal areas are to be reinforced by resin, use a soft resin. Please contact Panasonic when selecting the resin.
2.7.2 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 indoor use from
high places nor 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 indoor
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

Standard models come with silver or copper electrodes.
When it comes to the actual method of installation in the
product, please contact Panasonic.
Features and precautions
* These have a low contact resistance and are thus
suited to the zebra or heat seal connecting method.
* Their contact resistance is not increased by
oxidation, etc. of the electrode surfaces.
* The zebra connecting method, heat seal
connecting.
* Soldering or other such method may be used,
making available a wide-ranging power output
supply method.
* Temperature of soldering Iron: 220 to 280°C;
when soldering time is within 3 seconds.
* Use a soldering flux which complies with JIS
class B or milder or with MIL class RA or milder.
* There is no need to provide reinforcement with
resin after the leads have been attached by
soldering.
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 indoor 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).
2.7.3 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).
