Error code Description
E.01
PE connection error
The connections "E" or "KE" to earth are interrupted.
Action:
Check connection, eliminate error. The error code will be
erased automatically once the error has been eliminated.
E.02
Connection fault system (L1/+ , L2/-),
The internal resistance of the system is too high, the con-
nection "L1/+" or "L2/-" to the system is interrupted
or L1/+
and L2/- are connected in reverse polarity to the DC System to
be monitored (U
n
< -100 V).
Action:
Check connection, eliminate error. The error code will be
erased automatically once the error has been eliminated.
E.05
Measurement technique error/calibration invalid
For the current software version
E.07
The maximum permissible system leakage capacitance
C
e
is exceeded
Action:
Device not suitable for the existing system leakage capaci-
tance C
e
: uninstall device.
E.08
Calibration error during device test
Action:
If the error continues to exist after checking the device con-
