INSTALLATIONS
2.
The
PC 6300
should be placed in a dust-free
environment. Airborne dust, dirt, and smoke can cause
excessive wear on moving surfaces, short open circuits
(especially in the presence of high humidity), and read/write
errors on the disk.
3. The
PC 6300
should be placed away from heat and
direct sunlight. Unusually high temperatures coupled with
low humidity can cause static problems.
4.
The front and rear panels of the
PC 6300
should not
be obstructed. The PC 6300 is cooled by a fan located on
the rear panel. This fan pulls air in through air inlets on
the base of the System Module. The base of the System
Module should be free from papers or other materials that
would obstruct air flow.
5.
The System Module should not be placed in a small
enclosed area. The heat dissipation of the system is
140 watts (477.7 BTU/hour); this may be enough to raise the
temperature beyond the maximum allowed if enclosed in a
small area. This will also decrease the air flow around the
module.
