Operational temperature
-25°C to +70°C (-13°F to 158°F) The operational temperature is the ambient or
surrounding temperature and is defined as the
air temperature 2cm below the device.
Storage temperature
-40°C to +85°C (-40°F to 185°F) For storage and transportation

For altitudes >2000m (6560ft), see Fig. 15-2
For atmospheric pressures <80kPa, see Fig. 15-2
The de-rating is not hardware controlled. The customer has to take care by himself to
stay below the de-rated current limits in order not to overload the unit.

According to IEC 60068-2-6
Shock
30g 6ms, 20g 11ms
3 bumps / direction, 18 bumps in total
According to IEC 60068-2-27
Shock and vibration is tested in combination with DIN-Rails according to EN 60715 with a
height of 15mm and a thickness of 1.3mm and standard orientation.
LABS compatibility
As a rule, only non-silicon precipitating materials are used. The unit conforms to the
LABS criteria and is suitable for use in paint shops.
Corrosive gases
Tested according to ISA-71.04-1985, Severity Level G3 and IEC 60068-2-60 Test Ke
Method 4 for a service life of minimum 10years in these environments.
Audible noi
se Some audible noise may be emitted from the power supply during no load, overload or
short circuit.
