˜

For 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.

˜ For Power supply type P3 and P4, the high sensitive relay used in contact output may cause the chattering noise (wrong output of 1ms level) during ON and OFF operation, depending on the

Panel placing condition. When it is used in the quick responsive sequence, the filter circuit of a few milli-second (ms) should be provided or the double reading sampling should be implemented.

˜

˜

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 150V DC, 0.5A for 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.

˜ Since some terminals are polarized, the wiring should be done correctly as the polarity shown in the wiring diagram when the control voltage is DC. Auxiliary switch (AX) Standard type has no polarity.

˜ Alarm reset (Terminal: RS1 and RS2 ) is available only for Power supply type P3, P4 and P5.

For Power supply type P1 and P2, it can not be reset from the Control circuit terminal block ( RS1 and RS2 ).

˜ 513 574 P3 P4

˜ FG (Terminal: P4 ) is the protective earth for power supply (Terminal: P1 , P2 ).

It is recommended to use this terminal to reduce surge (M8 screw required).

˜ Shorting b-contact (SBC)

SBC can be provided for all AX b contacts. At the time of shipment from factory, SBC is already connected to control circuit terminal block. Only one more crimp terminal can be added on contact, overlapping with SBC’s contact on Terminal: 11 ~ 51 .
