First closing operation
If an undervoltage release 3AX1103-.. is fitted, it must be connected to control volt-
age for switching operations (mechanical or electrical), as otherwise closing is not
possible.
If all functions have been checked and are OK, switch on the high voltage while ob-
serving all of the safety regulations and operational requirements.
Electrically check auxiliary switch S1 and position switch in both end posi-
tions – operate the vacuum circuit-breaker to do so.
Check functioning of the closing solenoid Y9 and all existing 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 48)?
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
Faulty or damaged vacuum circuit-breaker
There is a risk of injury if the vacuum circuit-breaker is damaged or malfunctions!
• Immediately take the vacuum circuit-breaker out of operation.
• Do not put vacuum circuit-breaker back into operation.
• If the malfunctions or the damage cannot be remedied, contact a sales repre-
sentative or Siemens Service and, if necessary, send back the vacuum cir-
cuit-breaker.
