Immunity In order to document immunity towards
interference from electrical phenomena
external, the following immunity test has
been made on a system consisting of a
VLT
®
frequency converter (with options, if
relevant), a screened control cable and
control box with potentiometer, screened
motor cable and motor.
Fault criteria and test were in accordance
with EN50082-2 and IEC 22G/21/CDV.
The tests were made using the following
standards:
IEC 1000-4-2 (IEC 801-2/1991):
Electrostatic discharges (ESD)
Simulation of electrostatic discharges from
human beings.
IEC 1000-4-3 (IEC 801-3):
Incoming electromagnetic field radia-
tion
Simulation of the effects of radar and radio
communication equipment as well as
mobile communications equipment.
IEC 1000-4-4 (IEC 801-4):
Burst transients
Simulation of interference brought about
by coupling with a contactor, relays or
similar devices.
IEC 1000-4-5:
Surge transients
Simulation of transients brought about e.g.
by lightening that strikes near installations.
ENV50141:
Cable-borne HF
Simulation of the effect of radio transmis-
sion equipment coupled to connection
cables.
VDE0160 class W2 test pulse:
Mains transients
Simulation of high-energy transients
brought about by main fuse breakage,
coupling with phase-compensation
batteries, etc.
