On the
LEAK
COMP
®
1C
, a phase (L), the neutral conductor (N) and the protective earth
conductor (PE) must be connected in parallel to the electrical installation.
When selecting the phase, it must be ensured that it also supplies the "leakage current
generator", as compensating is impossible otherwise.
The phase and neutral conductor must be properly connected and must not be reversed.
Reversed phase and neutral conductors is indicated by the red LED (
ERROR
).
Compensation connection
The compensation connection (PE) on the
LEAK
COMP
®
1C
must be connected to the
protective conductor in a permanent and low-resistance manner. If the connection is
removed, this is indicated by the red LED (
ERROR
).
Control connection
The magnitude of the compensation current can be selected with a jumper between
control terminals C1 and C2.
If terminals C1 and C2 are open, the compensation current is 5 mA RMS.
If terminals C1 and C2 are connected (jumper provided from factory), the compensation
current is 11 mA RMS.
