Startup / Operation
DANGER
To prevent overcompensation, it is important that the
LEAK
COMP
®
1C
is always
switched on and off together with the leakage current generator.
An overcompensation is inadmissible, i.e. the compensation current must not be
higher than the leakage current.
IMPORTANT NOTE
The level of the compensation current (5 mA or 11 mA) must be selected before
commissioning the
LEAK
COMP
®
1C
.
To successfully deploy the
LEAK
COMP
®
1C
, it is necessary to first identify the
devices that are responsible for the leakage current and thus for tripping the RCCB. In
addition, the level of the leakage current before and after using the
LEAK
COMP
®
1C
should be measured in order to determine whether the compensation was successful
(see chapter “Comparing leakage current with and without the
LEAK
COMP
®
1C
”).
8.1
Switching on
When the supply voltage is switched on, the device first carries out a self-test, which
detects and if necessary corrects the correct assignment of the phase (
L
) and neutral
conductors (
N
) and the presence of the protective earth conductor (
PE
).
If phase and neutral are reversed or the protective earth conductor is missing, the
red
LED
flashes.
If too high of a potential difference between the neutral and protective earth conductor is
identified, then this is also detected by the
LEAK
COMP
®
1C
and indicated by a flashing
red LED
.
The
blue LED
serves as an operating display. A pulsating
blue LED
indicates that the
mains voltage is present, as well as proper connection of the phase, neutral conductor
and protective earth conductor and fault-free operation.
8.2
Switch compensation on and off
Compensation can be switched on and off by interrupting the conductor
PE
at the
compensating line.
8.3
Shutdown
To shut down the
LEAK
COMP
®
1C
,
disconnect the power supply to terminals
L
and
N
.
