Interconnections on COM15 for 3WL

In order to undertake switching operations of the circuit breaker in the faceplates of the 3WL,
the user must perform wiring on the COM15 module. This has to be done in order to forward
commands to the corresponding hardware.
The two circuits for the 24V DC voltage or other voltage levels only indicate complete
removal and can be adapted to specific users.
Contact 1 / 2:
Write protection is integrated in COM15 to interlock the switching operations of the circuit
breaker. This protection does not permit commands which put switching operations at risk.
Write protection on COM15 therefore has to be released via pin 2 in order to switch on or off.
The simplest version is depicted and takes the form of a wire jumper between 1 and 2
without customer-specific release (in released representation).
Contact 4 / 5:
These "User" contacts are used to control the magnets for the anti-pumping device and/or
trip detection. (The circuit breaker should be fitted with the "Remote reset magnet for the
display and reset button, including automatic resetting of the anti-pumping device")
Contact 6 / 7:
The "Close" / "Motorized operating mechanism for spring energy store" contact is used to
close the circuit breaker and controls the Y1 switch-on solenoids and the automatic charging
of the circuit breaker. (The circuit breaker should be fitted with the "Manual operating
mechanism with mechanical and electrical call, switch-on solenoid suitable for uninterrupted
duty, 100 % ED")
Contact 8 / 9:
The "Open" contact is used to switch off the circuit breaker and controls the F1 switch-off
solenoid. (The circuit breaker should be fitted with the "Shunt release suited to uninterrupted
duty, 100 % ED")
