200 to 240V
60Hz
Connect to a commercial power
supply. An AC reactor should be used
when measures for power harmonics
are taken, the power factor is to be
improved or the inverter is installed
near a large-capacity power supply
system (1000kVA or more). Refer to
page 507 for installation instructions.
Keep these terminals open when
using the high power factor converter
(FR-HC, MT-HC) or power
regeneration common converter (FR-
CV).

Power consumption
Connected to the AC power supply
terminals R/L1 and S/L2.
To retain the fault display and fault
output or when using the high power
factor converter (FR-HC, MT-HC) or
power regeneration common
converter (FR-CV), remove the
jumpers from terminals R/L1-R1/L11
and S/L2-S1/L21 and apply external
power to these terminals.

Brake
resistor
connection
terminal
(22K or less)
—
Remove the jumper from
terminals PR-PX (7.5K or less) and
connect an optional brake resistor
(FR-ABR) across terminals P/+-PR.
Keep terminal PR open.
Connect an optional
brake resistor (MRS, MYS, FR-ABR)
between terminal P/+ and PR. Not
compatible for 0.1K and 0.2K models.

Brake unit
connection
terminal
—
Connect the brake unit (FR-BU2),
power regeneration common
converter (FR-CV), power
regeneration converter (MT-RC) or
high power factor converter (FR-HC,
MT-HC).

DC reactor
connection
terminal
—
For the 55K or less, remove the
jumper across terminals P/+-P1 and
connect the DC reactor (FR-HEL).
(As a DC reactor is supplied with the
75K or more, be sure to connect the
DC reactor.)

PR, PX
Built-in
brake circuit
connection
terminal
—
When the jumper is connected
across terminals PX-PR (initial
status), the built-in brake circuit is
valid. The PX terminal is provided for
the 7.5K or less.
Keep terminal PR and PX
open.

Earth
terminal
—
Terminal for earthing (grounding) the
inverter chassis. Must be earthed
(grounded).
