See data sheet for further operating data.
The power input designated in the process-specific data sheet for the motor to be used as well as the adjustment of
the protective motor switch is significant. The motor current is to be limited so that the power input is maximally 15%
above that of the data sheet.
3 Temperature limits
With knowledge of the temperature class, the surface temperature of the compressor may exceed the
maximum allowable temperatures in the following table in no operating condition according to EN 13463-
1.
EN 13463-1 Surface temperatures (EN 13463-1)
Temperature class Limit values maximum allowable
for category 1
maximum allowable
for category 2
T 4 135 °C 108 °C 130 °C
T 3 200 °C 160 °C 195 °C
T 2 300 °C 240 °C 290 °C
T 1 450 °C 360 °C 440 °C
If the reference basis for the identification is a certain material, then the surface temperature for
compressors of
Category 1 may reach maximally 80% of the ignition temperature in °C
Category 2 - with ignition temperatures  200°C may reach values at least 5U
- with ignition temperatures > 200°C may reach values at least 10U
below the ignition temperature
