About Placement

This unit performs forced cooling by means of a cooling fan. Give attention to the
following points.

Never block the cooling-fan intake port or ventilation port in the rear panel. Doing so
may cause the temperature of the unit’s interior to rise, resulting in malfunction caused
by heat.
Clean away any buildup of dust in the intake port or ventilation port using a vacuum
cleaner or the like.

This unit can be installed in a rack. When installing the unit in a rack, to ensure efficient
cooling, give attention to the following points.
Ensure that the location provides good air flow and ventilation.
Never block the cooling-fan intake port or ventilation port in the rear panel.
Avoid using the S-4000D in sealed-type rack mounts. As this type of rack does not
permit heated air within the rack to be expelled, the heated air is drawn into the
S-4000D as a result, thus preventing adequately efficient cooling.
If the rack’s rear panel is not removable, ensure that a ventilation port or exhaust fan is
provided at the top of the rack’s rear panel to expel any accumulated heat.
If the S-4000D is mounted in a portable rack, remove both the front and rear rack covers
before use to ensure that the S-4000D’s front and rear panels remain unobstructed.
When installing the unit on a rack, detach the rubber feet from the bottom of the unit.

Use due caution when mounting the S-4000D in a rack or other enclosure so you don’t
get your fingers wedged or pinched.
