AMETEK CTS OCS 500 N6 series
Manual for Operation V 5.24 59 / 80
Test set-up
According to the specifications of IEC 61000-4-12, the surge generator has a source impedance of 12 or 30
when the simulator is coupled between the lines and protective earth.
This will activate fault current detectors or protectors which may be installed in the laboratory.
Therefore it is important
- Not to disconnect the surge simulator form protective earth (power cable)
- To have an installation where the simulator is connected via its ground reference connector to earth
Devices:
OCS500 : Ringwave test generator
CNV 504: Coupling network I/O lines
EUT: Equipment under test
CDN: Coupling/decoupling network
S: Insulating support
Ports
C1: Power supply port
C2: Input/output port
L: Communication port
GRP: Ground reference plane
PE: Protective earth
E: Earth connection
B: Power supply and I/O to source
NOTE - Earth connections should be as short as practically possible.
Application with CNV 504N
Coupling to coupling network CNV504 for
data lines. The earth cable must be
connected to the earth plug on the rear.
Application with CNV 508N4.1
