acc. to EN 60947-4-2
EMC interference immunity
Electrostatic discharge (ESD) EN 61000-4-2 ±4 kV contact discharge, ±8 kV air discharge
Electromagnetic RF fields EN 61000-4-3 Frequency range: 80 ... 1000 MHz with 80 % at 1 kHz
Degree of severity 3: 10 V/m
Conducted RF interference EN 61000-4-6 Frequency range: 150 kHz ... 80 MHz with 80 % at 1 kHz
Interference 10 V
RF voltages and RF currents on cables
• Burst EN 61000-4-4 ±2 kV/5 kHz
• Surge EN 61000-4-5 ±1 kV line to line
±2 kV line to earth
EMC interference emission
EMC interference field strength EN 55011 Limit value of Class A at 30 ... 1000 MHz,
limit value of Class B with 3RW40 2. 24 V AC/DC
Radio interference voltage EN 55011 Limit value of Class A at 0.15 ... 30 MHz,
limit value of Class B with 3RW40 2. 24 V AC/DC
Radio interference suppression filters
Degree of noise suppression A (industrial applications)
Not required
Degree of noise suppression B (applications for residential
areas)
Control voltage
• 110 ... 230 V AC/DC Not available 1)
• 115/230 V AC Not available 1)
• 24 V AC/DC Not required for 3RW40 2.;
required for 3RW40 3. and 3RW40 4. (see table)
1) Degree of noise suppression B cannot be obtained through the use of filters
as the strength of the electromagnetic field is not attenuated by the
filter.

1) The radio interference suppression filter is used to remove the conducted
interference from the main circuit. The field-related emissions comply with
degree of noise suppression B. Filter selection applies under standard
conditions: 10 starts per hour, start time 4 s at 300 % I e .
