Insertthe auxiliary contacts suitable signalling circuits. Open the circuit-breaker, turn the key and remove from its seat. The circuit-breaker opens correctly.2). The first turns the crank handle do not meet with particular resistance. P itiv ck The spring loading lever moves correctly. CAUTION When there undervoltage release, the circuit-breaker can only closed after the release has been electrically energized. Supply the undervoltage release the corresponding rated voltage (if any). Supply the shunt closing release its rated voltage. Disconnect voltage the release.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. The signals are correct. The signals are given correctly. Carry out some circuit-breaker closing and opening operations. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. The circuit-breaker closes correctly. Close the circuit-breaker. The geared otor stops with the springs loaded. 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. Open the circuit-breaker. Attempt circuit-breaker closing operation. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. The circuit-breaker opens. 15/158 . The signals are correct. The signals due the relative operations are given correctly. Carry out some racking-in and out operations. Racking-in operation: the circuit-breaker racks in correctly. The signals are correct. Supply the shunt opening release the corresponding rated voltage. Then put the circuit-breaker the connected, test isolated and disconnected position.Putting into service 6. Insertthe auxiliary contacts suitable signalling circuits. Carry out the operating tests. The geared motor reloads the springs after each closing operation. 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. Note. The springs are loaded correctly. The signal changes over. The signals are correct. Both anual and electrical closing are prevented. The locks function correctly. Supply the spring loading geared motor the corresponding rated voltage. The circuit-breaker closes correctly.
