Measurement testing (using both test sockets)
Terminal block Disconnect link operating position I
Terminal block Disconnect link measuring position III
Measurement testing: First insert the reference current meter (A) into the test socket, then move the disconnect link into
measurement point III (test current measurement).wago.
Disconnect link shorting position II
Test current measurement: Disconnect link measuring
position III
