Application Explanation
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).
Connect a three-phase squirrel-cage
motor.
The maximum output voltage does
not exceed the power supply voltage.
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.
Remove the jumper from
A700
terminals PR-PX (7.5K or less) and
connect an optional brake resistor
(FR-ABR) across terminals P/+-PR.
Keep terminal PR open.
F700
Connect an optional
E700 D700
brake resistor (MRS, MYS, FR-ABR)
between terminal P/+ and PR. Not
compatible for 0.1K and 0.2K models.
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).
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.)
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
F700
open.
Terminal for earthing (grounding) the
inverter chassis. Must be earthed
(grounded).
