(1) Transportation and mounting
CAUTION
! Do not install or operate the option unit if it is damaged or has parts missing.
! Do not stand or rest heavy objects on the product.
! Check that the mounting orientation is correct.
! Prevent screws, metal fragments or other conductive bodies or oil or other flammable substance from entering the inverter.
(2) Test operation and adjustment
CAUTION
! Before
starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to
make unexpected motions.

(3) Usage
WARNING
! Do not modify the equipment.
CAUTION
! When parameter clear or all parameter clear is performed, each parameter returns to the factory setting. Re-set
the required parameters before starting operation.
! For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate
static electricity from your body.
(4) Maintenance, inspection and parts replacement
CAUTION
! Do not test the equipment with a megger (measure insulation resistance).
(5) Disposal
CAUTION
! Treat as industrial waste.

2.INSTALLATION
2.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
CAUTION
With input power on, do not install or remove the option unit. Otherwise, the inverter and
option unit may be damaged.
2.2 Installation Procedure
(1) Securely insert the connector of the option unit far into the connector of the inverter. At this time, fit the
option fixing holes snugly. For the position of slot, refer to the next page.
Also be sure to fit the unit into the option fixing hook (For the FR-A500(L)/ FR-F500(L) series, it is available in Aug., 2000).
(2) Securely fix the option unit to the inverter on both sides with the accessory mounting screws. If the
screw holes do not match, the connector may not have been plugged snugly. Check for loose plugging.

INSTALLATION
2.3 Wiring
Route the wires so that they do not take up a lot of space in the control circuit terminal block of the option unit.
During wiring, do not leave wire off-cuts in the inverter. They may cause a fault, failure or malfunction.
Use the space on the left side of the control circuit terminal unit to route the wires.
Cable routing
REMARKS
The wires with large gaze may not be connected to the terminal block. When connected in parallel, all wires may not
fit in the wiring space due to the increased number of wires. In such cases, perform wiring by using a junction terminal block.
CAUTION
Do not use empty terminals as junction terminals because they are used in the option unit. If
they are used as the junction terminals, the option unit may be damaged.
When installing the inverter front cover, the cables to the inverter's control circuit terminals
and option terminals should be routed properly in the wiring space to prevent them from
being caught between the inverter and its cover.

5.THE COMMERCIAL POWER SUPPLY-INVERTER SWITCH-OVER SEQUENCE FUNCTION
If the commercial power supply-inverter switch-over sequence function is activated with the FR-A5AR mounted on
the inverter, the phenomenon where magnet contactor switches alternate between ON and OFF may occur.
To prevent this, adapt either connection shown below.
