required, external voltage can applied to
the measuring device via the test socket.
The transformer not disconnected from the measuring device yet, the shorting path activated moving the discon-
nect link into shorting position and the transformer safely shorted.

Disconnect link operating position I
Terminal blocks required:
2 disconnect/test terminal block (2007‑8821)
1 circuit jumper, orange (2007-8442)
Locking covers interlocking links (option)
In the operating position, the measurement device connected the transformer, the circuit jumper inserted and the
disconnect link position I.
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)
