8.4 LED display elements
The LEAK COMP
®
1C has two colour LED indicators.

Red LED High potential difference between neutral and protective earth
conductor
8.5 Setting the compensation current
The
LEAK
COMP
®
1C provides fixed compensation, meaning that the compensation
current is set to a fixed value for the respective application.
With an optimal compensation current level, the resulting 50 Hz leakage current is almost
zero.
The level of the compensation current can be selected with a jumper between terminals
C1
and
C2
. If terminals
C1
and
C2
are open, the compensation current is 5 mA RMS. If a
jumper is provided between
C1
and
C2
(from factory), the compensation current is 11 mA
RMS.

8.6 Further increasing the compensation current
If the compensation current is not sufficient to compensate for the leakage current,
additional LEAK COMP
®
1C devices can be connected in parallel.
Using a second LEAK COMP ®
1C
it is possible to generate 16 mA or 22 mA compensation
currents.
You must still ensure that no overcompensation occurs.
