Note. 15/158 . The signals are correct. 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. The circuit-breaker closes correctly. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. CAUTION When there undervoltage release, the circuit-breaker can only closed after the release has been electrically energized. Supply the spring loading geared motor the corresponding rated voltage. C arry som sin and ning operations. Supply the undervoltage release the corresponding rated voltage (if any). Model 2234 Apparatus Scale L 2778 Doc-Na 1SDH000460R0002 Page No.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. Supply the shunt closing release its rated voltage. Attempt circuit-breaker closing operation. The geared otor stops with the springs loaded. The signals are correct. Both anual and electrical closing are prevented. Carry out some circuit-breaker closing and opening operations. Open the circuit-breaker. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. Racking-in operation: the circuit-breaker racks in correctly. The springs are loaded correctly. Disconnect voltage the release. Carry out the operating tests. P itiv ck The spring loading lever moves correctly. The locks function correctly. The signals are correct. The circuit-breaker opens. 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 racking-in and out operations. The signals due the relative operations are given correctly. The signal changes over.2). Open the circuit-breaker, turn the key and remove from its seat. The signals are given correctly. The circuit-breaker opens correctly. Insertthe auxiliary contacts suitable signalling circuits. Supply the shunt opening release the corresponding rated voltage. Then put the circuit-breaker the connected, test isolated and disconnected position. Insertthe auxiliary contacts suitable signalling circuits. The geared motor reloads the springs after each closing operation. The circuit-breaker closes correctly. Close the circuit-breaker. The first turns the crank handle do not meet with particular resistance. The signals are correct.Putting into service 6
