Insulation fault location diagram
8.2 (2.1.2) Current
Set the maximum locating current on the ISOMETER®. The device-specific maximum locating
currents can be found in the table below.
Do not carry out a manual test during a manually started insulation fault loca-
tion, since the insulation fault location would be aborted by it.
CAUTION
Risk of malfunctions due to excessive locating current on sensitive
system parts! The locating current flowing between the IT system and earth
can cause controller faults in sensitive parts of the system, such as the PLC or
relay. Ensure that the level of the locating current is compatible with the
system to be monitored.
