Rail-Mount Terminal Blocks, TOPJOB® S
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.
TOPJOB® S
Implementing Current and Voltage Transformer Circuit
. 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.
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).99
