Connection of stand-alone option units

Connection example with the FR-BR(-H) type resistor
햲
If the control contacts are only specified for 230 V control power you must install a transformer
when using a 400 V power supply.
햳
Normal: across TH1-TH2 ... close, Alarm: across TH1-TH2 ... open
햴
Connect the inverter terminals (P/+, N/ ) and brake unit terminals so that their terminal signals
match with each other. (Incorrect connection will damage the inverter.)
햵
A jumper is connected across BUE and SD in the initial status.
햶
The wiring distance between the inverter, brake unit and resistor unit should be within 5m. If
twisted wires are used, the distance should be within 10 m.

Connection with the brake unit FR-BU2

CAUTION:
●
If the transistors in the brake unit should become faulty, the resistor can be unusually hot,
causing a fire. Therefore, install a magnetic contactor on the inverters input side to configure
a circuit so that a current is shut off in case of fault.
●
Do not remove a jumper across terminal P/+ and P1 except when connecting a DC reactor.
