Commissioning
Before commissioning, check the following points to ensure that the vacuum circuit-
breaker SION
®
is functioning faultlessly:
Checklist
Notes
Does the information on the rating plate (see page 28) match the order
data?
Ensure correct operating voltage.
Is the ambient temperature at least -5 °C (with addition A40 at least
-25 °C)?
If necessary, clean the vacuum circuit-breaker (details on this in section
“Cleaning” on page 51).
Check that screw connections are tightened securely.
Check terminal strip plug connection is seated firmly.
If necessary, check and adjust the customer's devices.
Test operation without supply voltage
Charge the closing spring with the hand crank (see Fig. 61), then press
the CLOSE pushbutton and, once closing has been performed, press the
OPEN pushbutton.
Test operation with supply voltage
To perform test switching with the motor, switch on the supply voltage.
The motor starts up immediately and charges the closing spring. Check
the indicator for charge state of the closing spring (mechanically and elec-
trically).
Electrically check through auxiliary switch S1 and position switch in both
end positions – operate the vacuum circuit-breaker to do so.
Check functioning of the closing solenoid Y9 and all available shunt
releases by operating them electrically.
If there is a 3AX1103 undervoltage release (Y7): Has the retaining screw
of the striker pin been shifted from position A to B (see “Removing the
transport block from the undervoltage release” on page 40)?
If there is a mechanical locking mechanism: Check if correct function of
mechanical locking is guaranteed as per IEC 62271-200.
If there are interlocks and a retrofitted key-operated interlock: Check if the
function of the interlocks as per IEC 62271-200 is guaranteed.
WARNING
Do not commission the vacuum circuit-breaker if there are malfunctions.
If the faults or the damage cannot be remedied, contact a sales representative or
Siemens Service and, if necessary, send back the vacuum circuit-breaker.
