This instruction manual (basic) provides handling information and precautions for use of the equipment.
Please forward this instruction manual (basic) to the end user.

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you
have read through this instruction manual (basic) and appended
documents carefully and can use the equipment correctly. Do not use the
inverter until you have a full knowledge of the equipment, safety
information and instructions. In this instruction manual (basic), the safety
instruction levels are classified into "WARNING" and "CAUTION".

Assumes that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.

Assumes that incorrect handling may cause
hazardous conditions, resulting in medium or
slight injury, or may cause physical damage only.

Note that even the level may lead to a serious consequence
according to conditions. Please follow strictly the instructions of both levels

because they are important to personnel safety.

1. Electric Shock Prevention

• While power is on or when the inverter is running, do not open the front cover.
Otherwise you may get an electric shock.m

• Do not run the inverter with the front cover or wiring cover removed.
Otherwise, you may access the exposed high-voltage terminals or the
charging part of the circuitry and get an electric shock.

•

Even if power is off, do not remove the front cover except for wiring or periodic
inspection.You may access the charged inverter circuits and get an electric shock.

• Before starting wiring, inspection or switching EMC filter on/off connector,
switch off the inverter power, check to make sure that the operation panel
indicator is off, wait for at least 10 minutes after the power supply has been
switched off, and check that there are no residual voltage using a tester or the
like. The capacitor is charged with high voltage for some time after power off
and it is dangerous.

• This inverter must be earthed. Earthing must conform to the requirements of
national and local safety regulations and electrical codes. (NEC section 250,

WARNING

CAUTION

CAUTION

WARNING

(2) Wiring

• Do not install a power factor correction capacitor, surge suppressor or radio

noise filter on the inverter output side.

• The connection orientation of the output cables U, V, W to the motor will affect
the direction of rotation of the motor.

(3) Test operation and adjustment

• Before starting operation, confirm and adjust the parameters. A failure to do
so may cause some machines to make unexpected motions.

(4) Operation

• When you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.

• The key is valid only when the appropriate function setting(refer to page

71) has been made. Prepare an emergency stop circuit (power off,

mechanical brake operation for an emergency stop, etc.) and switch
separately.

• Make sure that the start signal is off before resetting the inverter alarm. A
failure to do so may restart the motor suddenly.

• The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the inverter as well
as equipment.

• Do not modify the equipment.

• Do not perform parts removal which is not instructed in this manual. Doing so

may lead to fault or damage of the inverter.

• The electronic thermal relay function does not guarantee protection of the
motor from overheating.

• Do not use a magnetic contactor on the inverter input for frequent starting/

(2) Notes on earthing

• Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed. This inverter
must be earthed. Earthing must conform to the requirements of national and local safety regulations and electrical
codes. (NEC section 250, IEC 536 class 1 and other applicable standards)

• Use the dedicated earth terminal to earth the inverter.
(Do not use the screw in the casing, chassis, etc.)

• Use the thickest possible

earth

cable. Use the cable whose size is equal to or greater than that indicated in the above

table, and minimize the cable length. The earthing point should be as near as possible to the inverter.

To be compliant with the European Directive (Low Voltage Directive), earth the inverter according to

the instructions on page 135.

(3) Total wiring length

The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.

<Connection diagram> When the protected circuit is activated, opening of the electromagnetic

contactor (MC) on the inverter power supply side results in power loss in the
control circuit, disabling the alarm output signal retention. Terminals R1/L11
and S1/L21 are provided to hold an alarm signal. In this case, connect the
power supply terminals R1/L11 and S1/L21 of the control circuit to the
primary side of the MC.

2.5 Power-off and magnetic contactor (MC)

(1) Inverter input side magnetic contactor (MC)

On the inverter input side, it is recommended to provide an MC for the following purposes.

(

Refer to page 3 for selection.)

1)To release the inverter from the power supply when the inverter's protective function is activated or when the drive is
not functioning (e.g. emergency stop operation).

2)

To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure

3)The control power supply for inverter is always running and consumes a little power. When stopping the inverter for an
extended period of time, powering off the inverter will save power slightly.

4)To separate the inverter from the power supply to ensure safe maintenance and inspection work
The inverter's input side MC is used for the above purpose, select class JEM1038-AC3MC for the inverter input side
current when making an emergency stop during normal operation.

REMARKS

Since repeated inrush current at powering on will shorten the life of the converter part (switching life is 100 million times), frequent
on/off must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the inverter.

• Inverter start/stop circuit example

As shown on the left, always use the start signal
(ON or OFF across terminals STF or STR-PC) to
make a start or stop.

Precautions for use of the inverter

2.6 Precautions for use of the inverter

The FR-F700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method
may shorten the product life or damage the product.
Before starting operation, always recheck the following items.

(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.

(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.

(3) After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in
an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.

(4) Use cables of the size to make a voltage drop 2% maximum.

If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque
to decrease especially at the output of a low frequency.
Refer to page 12 for the recommended cable sizes.

(5) The overall wiring length should be 500m maximum.

Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to the
secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity of the
wiring. Therefore, note the overall wiring length. (Refer to page 13.)
