Connection of stand-alone option unit
It is recommended to configure a sequence, which shuts off power in the input side of the drive unit by the external thermal
relay as shown below, to prevent overheat and burnout of the brake resistor (MRS type, MYS type) and high duty brake
resistor (FR-ABR) in case the regenerative brake transistor is damaged. (The brake resistor cannot be connected to the
0.2K.)
Refer to the table below for the type number of each capacity of thermal relay and the diagram below for the connection.
When the power supply is 400V class, install a step-down transformer.

NOTE
The brake resistor connected should only be the dedicated brake resistor.
Brake resistor cannot be used with the brake unit, high power factor converter, power supply regeneration converter,
etc.
Do not use the brake resistor (MRS type, MYS type) with a lead wire extended.
Do not connect a resistor directly to terminals P/+ and N/-. This could cause a fire.
