3.4.1.
Earth protection
As a device with class l protection against electric shocks, it is essential to install a protective
earth wire (connect earth
). Connect the protection earth wire to the terminal (
X5
) before
connecting the grid to the grid emulator input.
On the other hand, connect the protection earth wire to the terminal (
X10
) before connecting
the EUT to the grid emulator output.

Input connection, terminals (X1 to X5).
Connect the grid cables
R
,
S
,
T

External isolation transformer
In case of isolation transformer, connect grid cables (R, S, T without neutral) to the primary of
the transformer (U1, V1, W1) and secondary of the transformer (U2, V2, W2, N2) to the input
terminals (
X1
), (
X2
), (
X3
) and (
X4
) of GE.
The ground cable (PE) of the main grid must be connected to ground transformer
