Environmental Operation
Conditions
•
Indoor use and altitude up to 2000m
•
Ambient Temperature
75 °F (24 °C)
•
Max. relative humidity 80% for temperatures up to 30ᵒC decreasing linearly to 50 % relative humidity at
40ᵒC
•
Mains supply volt fluctuations up to ±10 % of the nominal voltage
•
Transient overvoltage up to the levels of overvoltage category II (See Note 1).
•
Temporary overvoltage occurring on the mains supply.
•
Applicable pollution degree of the intended environment (pollution degree 2 in most cases (See Note 2).
Note 1: These levels of transient overvoltage are typical for equipment supplied from the building wiring.
Note 2: Manufacturers may specify more restricted environmental conditions for operation, nevertheless the
equipment must be safe within these normal environmental conditions.
