SUNCERAM II CELL FOR OUTDOOR USE - CONTINUED
3.7. Precautions for use
[Adhere strictly to the guidelines below since
mishandling the cells may impair their performance.]
3.7.1. Handling precautions for installation
It should be borne in mind that the Sunceram II cells for
outdoor use applications are energized by sunlight and
not by fluorescent or incandescent lights. For
applications such as back-up power for car batteries, in
vehicle-mounted products such as ventilator fans, radar
3.7.2. Handling precautions when installing cells in appliances
1. Connecting the leads
The table below shows the output terminal choices
available for the electrodes of the Sunceram II cells for
Construction of output terminals and precautions for installing cells in equipment
Electrodes
Copper electrodes
(C type)
Pre-Soldered electrodes
(S type)
With lead wire
(L type)
* Copper electrodes 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. Installing Sunceram II cells for outdoor use in
appliances
Improper installation of Sunceram II cells for outdoor
use in appliance may impair proper functioning of the
units.
Protecting Sunceram II cells for outdoor use with a
•
transparent cover
Protect Sunceram II cells for outdoor use from the
element with a transparent cover. Weatherproof
materials such as acrylic resin and polycarbonate are
recommended for this purpose. As shown in the
figure below, ideally, the shield should completely
cover Sunceram II cells for outdoor use.

detectors and deodorizers, and in teaching aids and toys,
these cells are designed to be suitable for uses which do
not involve direct and/or continuous exposure to rain
and wind. This not withstanding, they are used in all-
outdoor environments, (eg: garden lights, bicycle
headlights, outdoor clocks powered by solar cells, and
work indicator lights). If the cells are to be employed in
such ways, the following handling precautions must be
strictly adhered to.

outdoor applications. (The standard units have copper
electrodes.)
Features and precautions
* Temperature of the soldering iron tip 220 to 280°C
* Completion of soldering within 3 seconds.
* Soldering flux: Must comply with JIS class B or milder or with
MIL class RA or milder.
* Temperature of the soldering iron tip 220 to 260°C
* Completion of soldering within 3 seconds.
* Soldering flux Must comply with JIS class B or milder or with
MIL class RA or milder.
* Do not pull the leads beyond what is required.
Mounting Sunceram II
(1) To mount Sunceram II cells for outdoor use to
appliances, use a flexible means of a attachment
which will not accumulate heat, such as double-
sided adhesive tape.
(2) In mounting Sunceram II cells for outdoor use, do
not press down on the unit from above. If pressure is
absolutely necessary, press on the edge of Sunceram
II cells for outdoor use without compressing the
entire unit and use a soft material to grasp it.
(3) In mounting Sunceram II cells for outdoor use onto
appliances, allow some space between the
appliances and Sunceram II cells as shown in the
picture below. If no space is left, Sunceram II cells
for outdoor use may break through expansion and
contraction caused by heat. Use heat and weather-
proof materials for installation.
