Unless otherwise indicated, all electrical data in the following chapter refer to a 3-phase
AC voltage.
3.1 Operating conditions
3.1.1 Climatic environmental conditions
Storage Standard Class Description
Ambient temperature EN 60721-3-1 1K4 -25…55 °C
Relative humidity EN 60721-3-1 1K3 5…95 % (without condensation)
Storage height – – Max. 3000 m above sea level
Transport Standard Class Description
Ambient temperature EN 60721-3-2 2K3 -25…70 °C
Relative humidity EN 60721-3-2 2K3 95 % at 40 °C (without condensation)
Operation Standard Class Description
Ambient temperature EN 60721-3-3 3K3
5…40 °C (extended to -10…45 °C)
With temperature over 45 °C to max. 55 °C a
deration of 5 % per 1 K must be taken into con-
sideration.
Coolant inlet tem-
perature
Air – – 5…40 °C (-10…45 °C)
Liquid – – 5…40 °C
Relative humidity EN 60721-3-3 3K3 5…85 % (without condensation)
Type of protection EN 60529 IP20
Protection against foreign bodies > ø12.5 mm
No protection against water
Non-conductive pollution, occasional conden-
sation when PDS is not active.
Site altitude – –
Max. 2000 m above sea level
• With site altitudes over 1000 m a derating
of 1 % per 100 m must be taken into con-
sideration.
• From 2000 m, the control board has only
basic insulation to the mains. Additional
measures must be taken for the wiring of
the control unit.
