When the regenerative brake transistor is damaged, the following sequence is recommended
to prevent overheat and burnout of the brake resistor.
햲
Since the 00310 or more inverter is not provided with the PX terminal, a jumper is not need
to be removed.

Refer to the table below for the type number of each capacity of thermal relay and the diagram
below for the connection. (Always install a thermal relay when using the 00310 or more.)
