Before carrying out installation, wiring, mainte-
nance or inspection of the drive, read this in-
struction manual thoroughly to gain a full under-
standing of the correct operation procedures.
Make sure that you have read all product details,
safety information, warnings and cautions before
use. The following classifications for warnings
and cautions are used throughout this manual.
WARNING:
Denotes operating procedures and practices that
may result in severe injury or loss of life if not
correctly followed.
CAUTION:
Denotes operating procedures and practices
that, if not strictly observed, may result in per-
sonal injury or damage to the equipment.
WARNING:
FIRE AND PERSONAL INJURY HAZARD
This drive is designed for variable-speed opera-
tion of three-phase induction motors. It cannot
be used with single-phase motors or for any
other applications, otherwise fire may result.
The drive cannot be used by itself for elevators,
life-preservation equipment or other equipment
which is directly related to human safety. In such
situations, sufficient consideration should be
given to overall system configuration, not just to
the drive, otherwise serious accidents could
result.
INSTALLATION
WARNING:
FIRE AND PERSONAL INJURY HAZARD
Install the drive to a non-flammable surface such
as a metal surface, otherwise fires may result.
Do not place the drive near flammable materials,
otherwise fires may result.
Do not hold the drive by its cover when trans-
porting. The drive could be damaged and cause
injury to personnel.
Do not let any scraps of thread, paper, sawdust,
dirt, metal shavings or other foreign objects get
inside the drive or onto the cooling fins, other-
wise fire or problems with operation may result.
Do not install and operate the drive if it is dam-
aged or if some of the parts are missing. Doing
so may result in severe personal injury.
Do not touch the drive cooling fin because the
cooling fin reaches high temperatures during
operation, otherwise personal injury may result.
WIRING
WARNING:
FIRE AND ELECTRIC SHOCK HAZARD.
When connecting the drive to a power supply, be
sure to connect it via a circuit breaker, a leakage
current breaker or a fuse, otherwise fires may
result.
AC input fuses are required to validate the UL
listing of this device.
Use only fuses and circuit breakers with rated
capacities that are suitable for use with the drive.
Failure to do so may result in fire.
Connect the drive with a secure ground, other-
wise electric shocks or fires may result.
Wiring work should only be carried out by suit-
ably qualified personnel, otherwise electric
shocks may result.
Make absolutely sure that the power supply is
turned off (open) before wiring, otherwise electric
shocks may result.
Wiring work should only be carried out after the
drive has been installed, otherwise electric
shocks or injury may result.

CAUTION:
Do not touch the cooling fins, as they become
hot during drive operation.
Because it is relatively easy to set the drive to
high speed operation, be sure to check the
capacity of the motor and the equipment being
operated before changing the drive function
setting.
The drive braking function cannot be substituted
for mechanical means. Attempting to do so may
result in injury.
MAINTENANCE, INSPECTION AND PART
REPLACEMENT
WARNING:
ELECTRIC SHOCK HAZARD
Wait at least five minutes after turning off the
power before carrying out inspection. Check that
the charge indication lamp has gone out. Do not
touch the drive parts if the lamp is still lit, other-
wise electric shocks may result.
Maintenance, inspection and parts replacement
should only be carried out by suitably qualified
personnel. Remove any metallic accessories
such as watches and rings before starting work,
and use only properly insulated tools, otherwise
electric shocks may result.
DISPOSAL
CAUTION
Disposal of the drive should be entrusted to a
suitably-qualified disposal agency, otherwise
injury may result.
PACKING
CAUTION
Do not stand or sit on the drive as injury may
result.
The number of packing cartons that can be
stacked together is printed on the packing
container. Do not stack the containers any higher
than this or injury may result.
CAUTION:
Check that the phase and voltage of the AC
power supply being connected matches the
input phase and rated input voltage of the drive.
Using an improper power supply may cause
injury or damage to the equipment.
Do not connect AC power to the output termi-
nals (U, V, W) otherwise injury may result.
The drive, motor and wiring produce electromag-
netic noise during operation. Make sure that this
does not interfere with the operation of sensors
or other equipment nearby, otherwise accidents
may result.
OPERATION
WARNING:
ELECTRIC SHOCK HAZARD
Always install the drive cover before turning on
the power supply. In addition, do not remove the
drive cover while the power is on. Failure to
observe these precautions may result in electric
shocks.
Do not operate any of the switches with wet
hands, otherwise electric shocks may result.
WARNING:
FIRE AND PERSONAL INJURY HAZARD
If the retry function has been activated and a trip
occurs, the drive will restart automatically de-
pending on the cause of the trip. Make sure that
the system is set up properly so that there will be
no danger to personnel when the drive starts.
The STOP key is only effective when keypad
panel operation has been selected in the func-
tion settings. A separate switch should be
installed for emergency stopping purposes.
If an alarm reset is carried out while a run signal
(FWD/REV) is being input, the drive will suddenly
restart. Always check that the run signal is not
being input before carrying out the alarm reset,
otherwise accidents may occur.
Never touch the drive terminals while the power
is fed to the drive, regardless of whether the
drive is running or not.

Mounting Direction and Space
NOTICE: The durability and reliability of the
drive will be affected by the ambient tem-
perature. Do not place the unit where ambi-
ent temperature is not proper.
Direction: Insert M4 size screws in the
mounting screw holes in the left upper and
right lower of the drive, and install the drive
with these screws. Install the drive vertically.
Horizontal or other positional installation will
cause the drive to overheat.
Space: The drive will generate heat during
operation. Allow sufficient space around the
unit as shown in the above figure.
Mounting plate: Heat sink temperature will
reach +90°C during operation. Please use
thermostable material for drive mounting
plate.
Multi-mounting: When 2 or more drives are
installed within the drive switchboard, ar-
range them side by side, keeping space
(shown in the above figure) between each
drive. If the drives must be lined up vertically,
provide adequate ventilation so that the hot
air from each drive will not affect the one
above it.

CAUTION:
The control circuit terminal wiring should be
kept as far as possible from the main circuit
wiring to prevent operational error due to
noise interference. Never install them in the
same duct or conduit. (A separation dis-
tance of 4 inches [10cm] or more is recom-
mended.) If the control circuit wiring must
cross the main circuit wiring, make sure it
crosses at a right angle.
Use shielded, twisted wire for the control
circuit wiring , which should be as short as
possible (65 feet [20m] or less).
Install a surge absorber in parallel with any
magnet contactors, solenoids, relays or
timer coils, which are close to the drive.
Long wire lengths between the motor and
the drive will result in increased capacitance
and leakage current. This may cause earlier
activation of such protective function as
overcurrent protection, overheating protec-
tion and electronic thermal overload, or the
error in current detection may become large.
To avoid these, adjust the length of wiring
between the drive and the motor so that is
does not exceed the length shown below.

FVRF25 to 005C9S-2UX : 325 feet (100m)
