Settings
Do not carry out a manual test during a manually started insulation fault
location, since the insulation fault location would be aborted by that.
8.2 (2.1.2) Current
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.
Set the maximum locating current on the ISOMETER®. You can find the device-specific
maximum locating currents in the table below.
for EDS441-x
•1 mA
•2.5 mA for EDS441-x
•5 mA for EDS441-x
for EDS440-x
•10 mA
•25 mA for EDS440-x
•50 mA for EDS440-x
