For the FR-A820-00490(7.5K) or lower and the FR-A840-00250(7.5K) or lower, the jumper across terminals PR and PX must A brake resistor cannot be used with options such as brake units, high power factor converters, and power regeneration be disconnected before connecting the dedicated brake resistor. Doing so may damage the inverter. converters. Connection of the dedicated external brake resistor (FR-ABR) The FR-ABR can be applied to the FR-A820-01250(22K) or lower and the FR-A840-00620(22K) or lower.
