Monitor Output Applications
• The monitor output will be ON while current is flowing to the main
circuit. Use the monitor output, e.g., to switch the operation
indicator, or to switch control signals during forward/reverse rotation
or when a mechanical brake is used.
• Be sure to use a surge absorber when connecting an inductive load
to the monitor output.
Do not use two G3J-T or G3J-C Contactors together
for reversible operation.
