If you have any doubts or f~ndany damages tothe unlt, please contact your local service represen-
tatlve.
Carry and handlethe inverter carefully to prevent damage.
When carrylng the inverter, hold
it with care so that force is not applied to the fan at the bottom of
Inverter.
The inverter
IS protected w~th a plast~cenclosure. When carrylng the inverter, however, handle with
care so that undue force
IS not applied to the plastic cover.

I L?UkN1;;;ML°K ,
(1) Place the lnverter in a clean and well-ventilated location. Avoid locations exposed to dlrect
sunlight or subjected to high temperature, high humld~ty,dust or corrosivegases.
(2) Install the inverter securely with bolts or screws, vertically (fo that the letters "FREQROL-K"
on the front cover of Inverter, face front). Do not mount ;he inverter horizontally or aslant
because efficient ventilation will be impaire.
I
(3) Since the inverter generates heat to some degree, install any /other equipment or parts at least
10 cm away from the top and bottom of inverter and at least 5 cm away from both sldes of in-
verter to allow efficient heat dissipation.

Fig. 3 Mounting of lnverter
(4) Repeated breaking operation, may cause, the rear mounted discharging break resistor to reach
a maximum temperature of 150°C. Therefore mount the inv'erter to an incombustible surface
such
as concreteor metal. (See Fig. 2.)
(5) The FR-K serles inverters are available In two types of protective constructions according to
the output rating. Since the two types vary in the maximum allowable ambient temperature,
caution should be
exercised.
The maximum allowable amb~enttemperature of totally enclosed type lnverter is 40°C. By
removing the totally enclosingplates at thetop and bottom of inverter, the maximumallowable
amblent temperature can be changed to 50°C. (For the rehoval procedure, refer to page 6.)

5.1 Front Cover
To remove the front cover, as shown in Fig. 4, push down the whlte button located at the top
of inverter (arrow
a ), pull the top half of cover toward fron't (arrow a), and further push it
down lightly (arrow @ ). Then, the cover is removed from the chassis. Since mountingscrews
are not used, the cover can be d~smountedeasily.

As standard, the inverter is supplied wlthout cover fixing screws. However, the cover can also be
fixed by
use of mountlngscrews. Inthis case, ~nstallthe cover, referringtothe follow~ngworking
procedure and Fig.

Working procedure
(1 1 After removingthe front cover, drill holes wlth a drill, etc. at positionsshown in Fig. 6 from
the rear surface of cover. The hole diameter should be
4.5 to 5.0 mm.
(2) After installing the front cover, securely fix the cover by use of the following screws:

5.3 Totally EnclosingPlates
When the totally enclosed type inverters FR-K-S1500and FR-K-S2200are installedinside
a control
box, etc. and the temperature insidethe control box
is expected to exceed 40°C, only use the Inver-
ter after removing the totally enclosing plates located at the top and bottom. The removal pro-
cedure of totally enclosingplatesare shown in Fig.
8 and 9.
Since the totally enclosed type inverter is not of a waterproof construction, do not lnstall this type
of inverter outdoors or in
a place where the inverter can be splashed with water. oil. etc.
