-GN04H-ML2
If an External Regeneration Resistor is necessary, connect it between B1 and B2 as shown in the
diagram below.

-GN30H-ML2/-GN50H-ML2
If an External Regeneration Resistor is necessary, remove the short-circuit bar between B2 and B3,
and then connect the External Regeneration Resistor between B1 and B2 as shown in the diagram
below.
Connect the thermal switch output so that the main circuit power supply is
shut OFF when the contacts open. The resistor may be damaged by
burning, or cause fire if it is used without setting up a power supply shutoff
sequence using the output from the thermal switch.
Connect the thermal switch output so that the main circuit power supply is
shut OFF when the contacts open.
When using multiple External Regeneration Resistors, connect each
thermal switch in series.
The resistor may be damaged by burning, or cause fire if it is used without
setting up a power supply shutoff sequence using the output from the
thermal switch.
