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