Installation
Ambient Conditions
Location Requirements
The low temperature incubator must only be operated in a location that meets all of the
ambient condition requirements listed below:
• Installation location indoors in dry areas free from drafts.
• The dust burden may not exceed the contamination category 2 based on EN 61010-1.
Using the low temperature incubator in an atmosphere with electrically conductive dust is
prohibited.
• The minimal distance to adjacent surfaces must be observed on all sides (see Section
“Space Requirement” on page 3-3 )
• The operating room must be equipped with appropriate ventilation.
• Solid, level, fire-proof surface; no flammable materials opposite to the rear panel of the low
temperature incubator.
• Vibration-proof substructure (floor stand, lab table) capable of bearing the dead weight of
the low temperature incubator and its accessories (particularly if two devices are stacked).
• The electrical circuitry of the low temperature incubator has been designed for an
operating height of up to 2000 m above sea level.
• If a high-voltage test is to be performed on the unit, it must first be heated for around 30
minutes at 50°C.
• The ambient temperature must be within a range of +18 °C to +28 °C (64.4 °F to 82 °F).
• Avoid direct exposure to sunlight.
• Devices that produce excessive amounts of heat must not be placed near the low
temperature incubator.
• Place the low temperature incubator on a floor stand (option; to be ordered separately),
never on the lab floor. This prevents the penetration of dust or dirt into the device.
• Power line voltage variations must not exceed ±10 % of the nominal voltage.
• Transient surges must lie within the range of levels that normally occur in the power
supply system. The impulse withstand voltage based on surge category II of
IEC 60364-4-443 shall be applied at the nominal voltage level.
