10.3.3 Wiring diagrams for C.B. on withdrawable part
Note:
The wiring diagrams comprise the basic
components and all further equipment
options for the various VM1 types.
The scope of equipment possible within
an individual type series is listed in the
relevant switchgear list, and the
euquipment fitted in each individual case
can be found in the order
documentation.
-MS Supply voltage
-RL2 Blocking magnet for withdrawable part with
rectifier -TR5
-RL1 Closing lock-out (closed circuit)
-MO1 Switching command OFF 1 (open circuit)
-MC Switching command ON (open circuit)
-MU Switching command OFF (closed circuit)
-MO2 Switching command OFF 2 (open circuit)
-BB1 Auxiliary switch on the actuating shaft
-BB3 Auxiliary switch on the actuating shaft
-BB4 Fleeting contact (100 ms)
-BT2 Limit switch for withdrawable part in test
position
-BT1 Limit switch for withdrawable part in service
position
-DR READY for operation (NOC)
-DN NOT READY for operation (NCC)
-DO1 OFF signal (NOC)
-DC1 ON signal (NOC)
-DO2 OFF signal (NOC) (Full version)
-DC2 ON signal (NOC) (Full version)
Mode of presentation:
( ) Connection exists when auxiliary switches -BB1 and
1
-BB3 are not used.
See page 42 for comparison of IEC/VDE
designations.
Note:
If the READY contact -DR is to be polled,
the wiring diagram of the panel should
include the information that this contact
is already connected to blocking magnet
-RL2 and is therefore not isolated.
