Open the circuit-breaker. The signals are given correctly. The circuit-breaker closes correctly. The signals are correct. Carry out some racking-in and out operations. The signals are correct. The springs are loaded correctly. The signals are correct. Supply the spring loading geared motor the corresponding rated voltage. Carry out the operating tests. The circuit-breaker opens correctly. The circuit-breaker closes correctly. Model 2234 Apparatus Scale L 2778 Doc-Na 1SDH000460R0002 Page No. CAUTION When there undervoltage release, the circuit-breaker can only closed after the release has been electrically energized. Interlocking devices between circuit-breakers side by side and one top another (if any) 10 For withdrawable circuit-breakers: racking -in/out device P re Carry out some opening and closing operations (see the chapter 7. Carry out some circuit-breaker closing and opening operations. Both anual and electrical closing are prevented. C arry som sin and ning operations. P itiv ck The spring loading lever moves correctly. Close the circuit-breaker. The signal changes over. Supply the undervoltage release the corresponding rated voltage (if any). The circuit-breaker opens. Supply the shunt opening release the corresponding rated voltage.1 eneral s - Check tightness the power connections the circuit-breaker terminals - Carry out all the preparatory operations the release - Make sure that the value the auxiliary circuit power supply voltage between and 110% the rated voltage the electrical applications - Make sure that there adequate air circulation the place installation avoid overheating - Also carry out the checks specified the following table.2). ite d 1 Manual operating mechanism 2 Geared motor (if any) 3 Undervoltage release (if any) 4 Shunt opening release (if any) 5 Shunt closing release (if any) 6 Circuit-breaker lock the open position (with key padlocks) 7 Auxiliary contacts the circuit-breaker 8 Auxiliary contacts for signalling circuit- breaker connected, test isolated and disconnected 9 Lock vice circ it-b rs connected and disconnected. Open the circuit-breaker, turn the key and remove from its seat. Note. Disconnect voltage the release. The geared otor stops with the springs loaded. The locks function correctly. The signals are correct. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. Insertthe auxiliary contacts suitable signalling circuits.Putting into service 6. 15/158 . Supply the shunt closing release its rated voltage. The signals due the relative operations are given correctly. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. Insertthe auxiliary contacts suitable signalling circuits. Racking-in operation: the circuit-breaker racks in correctly. Then put the circuit-breaker the connected, test isolated and disconnected position. The geared motor reloads the springs after each closing operation. The first turns the crank handle do not meet with particular resistance. Attempt circuit-breaker closing operation
