SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
While power is on or when the inverter is running, do not open the front cover. You may get an electric shock.
!
Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage termi-
!
nals and charging part and get an electric shock.
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 or inspection, switch power off, wait for more than 10 minutes, and check for no residual
!
voltage with a tester or the like.

!
Always make sure that polarity is correct to prevent burst, damage, etc.
!
While power is on or for some time after power-off, do not touch the inverter as it is hot and you may get burnt.
!
3. Additional instructions

!
(2) Test operation and adjustment
AUTION
Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to
!
make unexpected motions.

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 thi s time, fi t 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.

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 t o the i ncr eased number of wires. In suc h 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 prop erly in the wiring space to prevent them from
being caught between the inverter and its cover.
