The signals are correct. The signals are correct. CAUTION When there undervoltage release, the circuit-breaker can only closed after the release has been electrically energized. The geared otor stops with the springs loaded. 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. 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. Close the circuit-breaker. The locks function correctly. The circuit-breaker closes correctly. Racking-in operation: the circuit-breaker racks in correctly. The first turns the crank handle do not meet with particular resistance. Model 2234 Apparatus Scale L 2778 Doc-Na 1SDH000460R0002 Page No. The signal changes over. The signals are given correctly. Open the circuit-breaker, turn the key and remove from its seat. Open the circuit-breaker. Supply the shunt closing release its rated voltage. The circuit-breaker closes correctly.
