Note;
● On the drawout type, the cables should have the length which allow the control circuit terminal block to be moved to the left or right by 5mm.
●
When a coil load is connected in the same control circuit as the ETR, surge absorbers are required to absorb the surge voltage.
● OCR alarm (AL)
The contact output of the OCR alarm(Standard type AL) is the one-pulse output and the output time is 30~50ms.
For this reason, this output needs self-holding circuit.
●
Closing coil (CC)
As CC is one-pulse driven, it is not necessary to insert AXb for burning prevention purposes.
Inserting AXb will cause anti-pumping function to be ineffective.
●
Under voltage trip device (UVT)
Use the switch that can open and close DC150V, 0.5A to remote trip.
Remote trip terminal has short bar at shipment, so remove it before using this function.
Disconnect the voltage input wires during dielectric testing of main circuit.
● voltage. (longer than 1sec.)
