4.1.2.6 Button Power LINE PWR1 (24)
With this button the EUT power is turned on or off at the phase angle defined.
4.1.2.7 Button Variac (25)
With this button the EUT power is turned on from the varic. When the power of the EUT is feed from input
(48) (see Figure 4.2 ) e.g. internal or external variac, this status will be indicated by the LED (25) .
4.1.2.8 Synchro ON EUT Power (36)
When a voltage higher than 30 V is applied at the EUT power 1 input on the rear side of the TRA3000 F-S-
D-V-C, the synchronisation will be referred to the supply voltage. The LED (36) indicates whether the
synchronisation is based on the EUT power voltage or not. At voltages lower than 30 V the synchronisation
is based on the power line of the TRA3000 F-S-D-V-C (41). If the phase and the neutral are interchanged,
no indication will occur.
4.1.2.9 High voltage pulse output EFT (27)
This output is needed to run EMC tests with the external capacitive coupling clamp or an additional
coupling/de-coupling network.
4.1.2.10 Control plugs EXT-TRA3000 E (29)
This connector is for connecting the ESD discharge circuit accessory EXT-TRA3000 E. See TRA3000 F-S-
D-V-C accessories.
4.1.2.11 Impulse output SURGE (30,31)
These two connectors are for connecting the SURGE coupling kit accessory or three phase coupling/de-
coupling networks. See TRA3000 F-S-D-V-C accessories.
The outputs are marked with „high“ and „low“. The „low“ output is not earthed, and a maximum external
voltage of 280 V ac can be connected, as described on the front panel.
4.1.2.12 High voltage (35)
Attention high voltage at the EFT BNC plug) and SURGE ( MC plugs)
4.1.2.13 Earth connection (34)
Particularly for interference tests with high frequency components, such as EFT, a large surface earth
connection is necessary. The earth terminal of the TRA3000 F-S-D-V-C allows a low inductance earth
connection between test equipment and the reference ground plane to be made.
4.1.2.14 Attention, refer to manual (32)
This sign tells the operator to study the manual in detail. Only trained personnel are allowed to operate the
TRA3000 F-S-D-V-C.
