Installation location indoors in dry areas free from drafts.
The dust pollution may not exceed the contamination category 2 based on EN
61010-1. Using the environmental chamber in an atmosphere with electrically
conductive dust is prohibited.
The room must be equipped with appropriate ventilation. Solid, level, fire-proof
surface; no flammable materials opposite to the rear panel of the environmental
chamber.
The electrical circuitry of the environmental chamber 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 16°C - 32°C (61°F to 90°F).
Devices that produce excessive amounts of heat must not be placed near the
environmental chamber.
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.
Relative humidity up to 80%, non condensing, at an ambient temperature of 31°C,
decreasing linearly to 50% at 40°C non condensing.
Please note: Should condensation exist, wait until the moisture has evaporated
completely before connecting the environmental chamber to a power source and
powering up.
WARNING
Connect to suitable power supply only.
See chapter Technical Specifications for specific power input for the respective
unit.
