2.1 Ambient Conditions

(in accordance with DIN EN 61010)
The unit may only be operated:
• Indoors.
• Up to an altitude of 2,000 m above sea level.
• At an ambient temperature range between
5 - 40ºC [41 - 104ºF] *).
• At a maximum relative humidity of 80% at 31°C
[87.8°F], dropping in a linear manner to 50% rela-
tive humidity at 40°C [104°F] *).
• With mains power where the voltage fluctuations
do not exceed 10% of the nominal value.
• Under over-voltage category II conditions.
• Under contamination level 2 conditions.
*) Between 5 – 30°C [41 – 86°F], the unit can be operated at
a relative humidity of up to 80%. At temperatures between
31 - 40°C [87.8 - 104°F], the humidity must decrease
proportionally in order to ensure operational readiness (e.g., at
35°C [95°F] = 65% humidity; at 40°C [104°F] = 50% humidity).
The unit may not be operated at temperatures above 40°C
[104°F].
