Carry out some racking-in and out operations. The circuit-breaker opens. Note. The signals are correct. Supply the spring loading geared motor the corresponding rated voltage. Open the circuit-breaker, turn the key and remove from its seat. The geared motor 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 Procedure Carry out some opening and closing operations (see the chapter 7. Close the circuit-breaker. Attempt circuit-breaker closing operation. The circuit-breaker closes correctly. Disconnect voltage the release. Supply the shunt closing release its rated voltage. Model L3447 A pparatus Emax DC S cale D oc-N 1SDH000635R0002 Page No. Carry out the operating tests. 14/1 08 . The geared motor reloads the springs after each closing operation. CAUTION When there undervoltage release, the circuit-breaker can only closed after the release has been electrically energized. The signal changes over.2). The circuit-breaker opens correctly. The signals are correct. The circuit-breaker closes correctly.Putting into service 6. The locks function correctly. Item inspected 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 vice irc it-b rs connected and disconnected. Supply the undervoltage release the corresponding rated voltage (if any). Open the circuit-breaker. Both anual and electrical closing are prevented. Then put the circuit-breaker the connected, test isolated and disconnected position. 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. Insert the auxiliary contacts suitable signalling circuits. C arry som sin and g operations. Carry out some circuit-breaker closing and opening operations.1 eneral res - 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 first turns the crank handle do not meet with particular resistance. The signals due the relative operations are given correctly. The signals are given correctly. The signals are correct. Insert the auxiliary contacts suitable signalling circuits. S upply the undervoltage release the corresponding rated voltage and carry out the circuit-breaker closing operation. Supply the shunt opening release the corresponding rated voltage. The springs are loaded correctly. The signals are correct. Positive check The spring loading lever moves correctly
