Technical item or function Technical data
Pollution degree PD2
Altitude 0–4000 m (0–13100 ft) above sea level: in case network is not
corner-grounded (Voltage class 5).
Above 1000 m (3300 ft): derating of the output current by 1% per
each 100 m is required.
Vibration (IEC60068-2-6) Displacement amplitude 0.5 mm (peak) at 5–22 Hz)
Maximum acceleration amplitude 1 G at 22–150 Hz
Shock (IEC60068-2-27) maximum 4 G, 11 ms (in package)
Sound pressure level 1 system module in cabinet: 80 dB(A)
+3 dB(A) increase for every additional power unit
1) On board level on coated boards.
