* Do not remove the jumper across terminal P/+ and P1 except when connecting a DC reactor.
When the regenerative brake transistor is damaged, the following sequence is recommended to prevent overheat
and burnout of the brake resistor.
*1 Since the 11K or higher inverter is not provided with the PX terminal, a jumper is not need to be removed.
*2 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 11K or higher)

CAUTION
⋅ The brake resistor connected should only be the dedicated brake resistor.
⋅ The jumper across terminals PR and PX (7.5K or lower) must be disconnected before connecting the dedicated brake resistor.
Doing so may damage the inverter.
⋅ Brake resistor cannot be used with the brake unit, high power factor converter, power supply regeneration converter, etc.
