2.1.1 Instructions for installation
1) Handle the unit carefully.
The inverter uses plastic parts. Handle it gently to protect it from damage. Also, hold the unit with even strength
and do not apply too much strength to the front cover alone.
2) Install the inverter where it is not subjected to vibration.
Note the vibration of a cart, press, etc.
3) Note on ambient temperature
The inverter life is under great influence of ambient temperature. In the place of installation, ambient temperature
must be within the permissible range (-10°C to +40°C (14°F to 104°F) ). Check that the ambient temperature is
within that range in the positions shown in figure 3).
*For FR-A560L-375, 450K at constant torque (CT) rating maximum ambient temperature can be 50°C (122°F).
4) Install the inverter on a non-combustible surface.
The inverter will be very hot (maximum. about 150°C (302°F) ). Install it on a non-combustible surface (e.g.
metal). Also leave sufficient clearances around the inverter.
5) Avoid high temperature and high humidity.
Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.
Note: The cooling section outside the enclosure has the cooling fan. Do not use the inverter in any environment
where it is exposed to waterdrops, oil mist, dust, etc.
6) Avoid places where the inverter is exposed to oil mist, flammable gases, fluff, dust, dirt, etc.
Install the inverter in a clean place or inside a "totally enclosed" panel which does not accept any suspended
matter.
7) Note the cooling method when the inverter is installed in an enclosure.
When an inverter is mounted in an enclosure, the ventilation fans of the inverter and enclosure must be carefully
positioned to keep the ambient temperature of the inverter below the permissible value. If they are installed in
improper positions, the rise in ambient temperature will result in reduced performance of the inverter.
8) Secure the inverter vertically, with bolts.
Install the inverter on an installation surface securely and vertically with screws or bolts.

2.2.2 Wiring of the main circuit
(1)
Wiring instructions
1) Power must not be applied to the output terminals (U, V, W) of the inverter. Otherwise the inverter will be
damaged.
2) After wiring, wire off-cuts must not be left in the inverter.
Wire off-cuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
3) Use thick cables to make a voltage drop of 2% or less.
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.
4) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes harmonic components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, use shielded wire cables as
the power cable.
5) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF option) in the output side of the
inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above
devices are installed, immediately remove them.
6) When rewiring after operation, make sure that the POWER lamp has gone off, and when more than 10minutes
have elapsed after power-off, check with a tester that the DC bus voltage is zero. After that, start rewiring work.
For some time after power-off, there is a dangerous voltage in the capacitor.
7) Top attachments should be removed before operating because of Air exhaust. Side attachments can be used
for fixing the unit. (See page 44)
Notes on Grounding
• Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be grounded
(grounding resistance: 10Ω or less.)
• Use the dedicated ground terminal to ground the inverter. (Do not use the screw in the case, chassis, etc.)
• The ground cable should have a thickness of 38mm2, or more, and be as short as possible. The grounding
point should be as close to the inverter as possible.

Connecting the control circuit to a power supply separately from the main circuit
If the magnetic contactor (MC) in the inverter power supply is opened when the protective circuit is operated,
the inverter control circuit power is lost and the alarm output signal cannot be kept on. To keep the alarm
signal on terminals R1 and S1 are available. In this case, connect the power supply terminals R1 and S1 <L
11
and L
21
> of the control circuit to the primary side of the MC.
<Connection procedure>
Note: 1. W hen the main circuit power (R, S, T) <L
1
, L2, L3,> is on, do not switch off the control power
(terminals R1, S1<L
11
, L21>). Otherwise the inverter may be damaged.
2. W hen using a separate power supply, the jumpers across R-R1 and S-S1 <L
1-L11
and
L
2-L21
>must be removed. Otherwise the inverter may be damaged.
3. For a different power supply system which takes the power of the control circuit from other than
the primary side of the MC, the voltage should be equal to the main circuit voltage.
4. The power supply cables must not be connected to the lower terminals. If connected, the inverter
may be damaged.

2.2.3 Wiring of the control circuit
(1)
Wiring instructions
1) Terminals SD, SE and 5 are common to the I/O signals and isolated from each other. These common terminals
must not be connected to each other or earthed.
2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main
and power circuits (including the 200V relay sequence circuit).
3) The frequency input signals to the control circuit are micro currents. When contacts are required, use two or
more parallel micro signal contacts or a twin contact to prevent a contact fault.
4) It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running
or the cables are run improperly, resulting in an operation panel or parameter unit contact fault.

<Wiring procedure>
1) For the wiring of the control circuit, strip the sheaths of the cables and use them as they are.
Strip the sheath to the following dimension. If too much is stripped this may cause a short circuit with
the neighboring cable. If too little stripped this may cause cable disconnection.
6mm ± 1mm
2) Loosen the terminal screw and insert the cable into the terminal.
3) Tighten the screw to the specified torque.
Undertigthening can cause cable disconnection or malfunction. Overtightening can cause a short circuit or
malfunction due to the screw or unit damaged.
Tightening torque : 5 to 6 kgf･cm
Note : Wire the stripped cable by twisting it to prevent it from becoming loose. (Do not plate the cable with
solder.)
Note : 1. Use a NFB (No fuse breakers) or fuse on the inverter input (primary) side.
2. Make sure that the control circuit terminal wiring does not touch power circuit terminals (or
screws) or conducting power circuit.
