General Information ETAS
Ven tilation
If the ES4441.1 is being operated in the ETAS LABCAR system casing (see "Inten-
ded Use" on page 9) make sure you observe the following points:
• The casing and particularly the air vents must be at least 15 cm away from
walls and objects in the environment.
• Leave the casing open at the back.
When the ES4441.1 is being operated in a 19" rack, make sure you observe the
following points:
• The air vents must be at least 15 cm away from walls and objects in the
environment. Make sure there is a gap of at least 1 U to the next compo-
nent, both above and below.
• The ambient temperature in the rack must not exceed the permissible
maximum value (see "Environmental Conditions" on page 78) of 40 °C /
104° F.
Rack System
The ES4441.1 is intended exclusively for operation inside a suitable rack system.
The rack system must have the following properties to ensure protection against
the spread of fire and to prevent contact with a possibly hot-to-the-touch
ES4441.1housing:
• Rack with closed bottom board or bottom with “UL perforation”
*
. Alter-
natively, the bottom may be covered with drip protection boards. The area
to be covered is defined in EN 61010-1:2010 + Cor.:2011, §9.3 (see in
particular §9.3.2/Image 12 „drip protection“). The drip protection boards
must be installed with overlaps to create a completely covered bottom of
the rack. The bottom board or the drip protection boards must be metal
or another fire-retardant material according to IEC 60695-11-10 V1 (or
better). The bottom board or drip protection boards must be sufficiently
sturdy.
• Closed sides and rear, i.e. fully closed rear door and fully closed panels on
both sides of the rack.
• Sufficient active ventilation. Adequate ventilation must be assured and
verified. If necessary, a suitable temperature sensor in connection with an
power-off switch must be installed to interrupt the power supply in case
of overheating. This power-off mechanism must be fail-safe.
All above properties must be fulfilled and guaranteed. Further it must be ensured
that there are no combustible materials/parts in the vicinity of bottom, lid, side
panels, or pack panel.
*UL Perforation: This refers to perforation according to the guidelines in table 16
„Permissible hole size in the bottom of a housing” of IEC EN 61010-1:2010 +
Cor.:2011, §9.3 “Containment of fire within the equipment, should it occur “
