Operating Instructions

Indicates that the EV charger needs to be reset.
Shows the status of the RCD under test.
5.11 RCD Trip Time Tests (x1/2, x1 and x5)
The DL9120 / DL9130EV will only allow the RCD test to be
performed if the correct voltages are detected between line-
earth (L-PE illuminated), line-neutral (L-N illuminated) and
neutral-earth (N-PE
not
illuminated).
Potential fields from other earthing installations, large
voltages between the protective conductor and earth, large
voltage between the neutral and earth or leakage currents
in the circuit following the residual current protection device
may influence the measurement.
Equipment which is connected downstream of a residual
current protective device (RCD) may cause a considerable
extension of the operating time.
The DL9120 / DL9130EV will determine the fault voltage
that may appear on the protective conductor during the test.
If the fault voltage is greater than 25V the DL9130EV will
indicate >25V on the LCD, but the user may proceed with
the test. If the fault voltage is great than 50V, this is
indicated on the LCD and the test is inhibited.
Use the rotary switch to select the ½ I
n, I
n or 5 I
n test position.
The ½ I
n test will perform the RCD test with a current of 50% of that
indicated on the LCD.
The I
n test will perform the RCD with the test current indicated on the
LCD.
The 5 I
n test will perform the RCD with 500% that which is indicated on
the LCD.
