Tighten the terminal screws to the specified torque. Undertightening can cause an
inter-terminal short circuit or malfunction. Overtightening can cause the screws and
unit to be damaged, resulting in a short circuit malfunction or the like.
Connect to the commercial power supply.
Connect to a dedicated variable-speed synchronous motor.
Connected to the AC power input terminals R, S. To retain
the alarm display and alarm output, remove the jumpers from
the terminal block (across R-R1 and S-S1) and input external
power to these terminals.
Disconnect the jumper from terminals PR-PX and connect the
FR-ABR brake resistor (option).
Disconnect the jumper from terminals P/+-P1 and connect the
FR-BEL power factor improving DC reactor (option).
Connect to the BU brake unit (option) or FR-HC high power
factor converter (option).
When the jumper is connected across terminals PX-PR
(factory setting), the built-in brake circuit is enabled.
Terminals for connection of the ground cables. (There are two
terminals.)
