SAFETY INSTRUCTIONS
!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.

2.INSTALLATION
2.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
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 avail-
able 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. Checkfor loose plugging.
With input power on, do not install or remove the option unit. Otherwise, the inverter and
option unit may be damaged.

INSTALLATION
CAUTION
1. Only one type of option per inverter may be used. When two or more options are mounted, pri-
ority is in order of slots 1, 2 and 3, the options having lower priority are inoperative.
2. When the inverter cannot recognize that the option is
mounted, it displays the option error. The errors shown
differ according to the mounting slots 1, 2, 3.
3. When one FR- A5NR is used with the other communica-
tion option than the FR- A5NR, no error is displayed and
the relay output of the FR- A5NR and the communication
function of the other communication option are made valid.
