General electrical data
EMC Compliance with the requirements acc. to EN 61800−3
Noise emission Compliance with the limit class C2 according to EN 61800−3(achieved
with a collective filter typical for the application)
Noise immunity Requirements acc. to EN 61800−3
Requirement Standard Severity
ESD 1) EN 61000−4−2 3, i. e.
l 8 kV for air discharge
l 6 kV for contact
discharge
Conducted high
frequency EN 61000−4−6 10 V; 0.15 ... 80 MHz
RF interference
(housing) EN 61000−4−3 3, i. e. 10 V/m;
80 ... 1000 MHz
Burst EN 61000−4−4 3/4, i. e. 2 kV/5 kHz
Surge (surge voltage on
mains cable) EN 61000−4−5 3, i. e. 1.2/50 ms
l 1 kV phase/phase
l 2 kV phase/PE
Insulation resistance EN 61800−5−1, UL 840: Overvoltage category III
Discharge current to PE
(Acc. to EN 61800−5−1) > 3.5 mA AC
Enclosure IP20 for
l Standard installation (built−in unit)
l Cold−plate technique
l Mounting with thermal separation (push−through technique), IP54
on heatsink side
Protective measures against l Short circuit in power terminals (short−circuit−proof at mains
connection)
l Short circuit in auxiliary circuits
– Digital outputs: Short−circuit−proof
– Bus and encoder systems: Limited protection against short circuit
(if necessary, monitoring functions can be switched off, in this
case, error messages must be reset:)
l Earth fault (earth−fault protected at mains connection)
l Overvoltage
Protective insulation of control circuits Protective separation from the mains
Double/reinforced insulation acc. to EN 61800−5−1
1) The noise immunity with the severities given must be ensured by the control cabinet.
The user must check the compliance of the severities given.
