Pulse-shaped disturbance variables of motor starters
The following table shows the electromagnetic compatibility of the ET 200SP motor starters
with regard to pulse-shaped interference.
Table 14- 3 Pulse-shaped disturbance variables
Pulse-shaped disturbance variable
Burst pulses (fast transients) in
accordance with IEC 61000-4-4,
tested with 5 kHz.
±2 kV (24 V supply cables)
±2 kV (500 V AC infeed*)
±1 kV (signal cable <30 m)
3
*If you mount the motor starter to the right of a 15 mm or 20 mm I/O module or immediately next to a
header module, use a dummy module. You will find further information in "Selecting motor starters
with a suitable BaseUnit (Page 38)."
High-
energy single pulse (surge) in
accordance with IEC 61000-4-5
500 V AC infeed
±2 kV conducted interference - phase to
ground
±1 kV conducted interference - phase to phase
24 V supply cable:
±1 kV conducted interference - phase to
ground**
±0.5 kV conducted interference - phase to
3
**External protective circuit required (see the Function Manual Designing interference-free controllers
(http://support.automation.siemens.com/WW/view/en/59193566)) if values of 2 kV (phase to ground)
or 1 kV (phase to phase) are required.
