within the following conditions:
1)
Terrestrial applications only—no outer
space use.
2)
The ambient temperature must be
within –20°C (-4°F) to 46°C (115°F).
The temperature limits are defined as
the monthly average low and high of
the installation site.
3)
The
wind
pressure
installation site should be less than
1,440Pa (30PSF)*.
*Note: HIT Double modules were
tested at 30PSF at UL's testing lab.
Modules of exactly the same structure
successfully achieved 50PSF load
ratings at JET's (Japan Electrical
Safety & Environment Technology
Laboratories) testing lab, and are
certified as fully compliant at 50PSF.
4)
Modules must not be installed nor
operated in areas where, salt, hail,
snow,
sand,
dust,
chemically active vapors, acid rain,
soot, etc., are excessive.
