a
These measurements assume that the autoloader is installed in accordance with the instructions in this manual.
b
The autoloader is in its original packaging. The packaging is designed to protect the autoloader from condensation caused by extreme
temperature variations (15° C or more). When the autoloader is moved from a cold storage environment to a warm operating
environment, it must be acclimated in its packaging for at least 12 hours before opening to prevent serious condensation damage
from occurring.
c
The autoloader has been unpacked.
d
The autoloader has not been unpacked. The transportation period does not exceed 72 hours.
e
The upper ambient operating temperature limit of +40° C (+104° F) is specified at +914.4 m (+3,000 feet), derated linearly to +24° C
(+75.2° F) at +3,048 m (+10,000 feet).
f
The data cartridges’ temperature and humidity must be allowed to stabilize in the specified ambient environment for 24 hours.
