26 Installation Coupling (main body and cradle) Please, put 'disconnected' position by turning lever to the left side. This 'disconnection' position prevents the extraction of the right handside rail. Then, pull the handgrip to drawout the circuit breaker. Please, put circuit breaker at the right position to match 4 supports to rail home on both parties. On the circuit breaker, push the green button to make the circuit breaker 'Open' automatically during connection. Please, do not press hard on the OCR Control Unit during installation. Push the Circuit Breaker into the cradle. In connected position, main and auxiliary circuits are connected for energizing.

27 26_27 Air Circuit Breaker / Automatic Transfer Switch Separation Open the breaker. Otherwise, it will open automatically during disconnection. If the breaker is in charge, please close the breaker first by clicking 'ON' button. Then, push '' button and open it. CAUTION: for Drawout Breaker w/fixed connection, please disconnect them first.

28 Indication ON ON The figures show the status of indication at the different positions.

29 28_29 Air Circuit Breaker / Automatic Transfer Switch Electrical closing The Closing Relay operates at 85%~110% of the Rated Voltage. The closing spring of circuit breaker is automatically charged by external power source. Otherwise, charge is manually. NOTE: The breaker can be close only if it is open, charged and no tripping are simultaneously ordered. The CC withstands a continuous power supply, providing antipumping function. If the breaker is not ready to close when the closing order is intended. wired in series with the ready to close contact C, a closing order can be transmitted only if the breaker is ready to close. (Inhibition of the antipumping function) Please, press the push ON button Electrical trip The Shunt Trip operates at 85% of the Rated Voltage. Or an Undervoltage release UVT or delayed undervoltage release UVR. (Tripping between 0.35 to 0.7 Un) (for the UVR, delay adjustable to 0.5~3 seconds, front cover removed) Please, press the push button
