FR-F 740 EC/E1
SYSTEM DESCRIPTION
International standards
The inverters of the FR-F 740 EC series are
designed so that they can be used world-
wide without any additional modifications
or certifications.
Ȝ
The units conform to the international
CE, UL, cUL, Gost and CCC standards.
Ȝ
User-selectable positive or negative
switching logic. Users can select posi
-
tive or negative switching logic for in
-
put and output signals, enabling
flexible and simple adaptation of the
units for varying world market
requirements.
Ȝ
Extended input power voltage range:
3~ 380-480 V (up to 500 V for 01800 and
above), 50/60 Hz
Tolerance: −15%; +10%
Ȝ
Multilingual programming/control unit
(optional)
Ȝ
Support for a variety of international in-
dustrial bus systems
Ȝ
Internationally standardised, frequency
inverter configuration software package
for MS Windows, with multilingual user
interface
These features make the FR-F 740 EC a truly
international product that meets all relevant
standards and can be easily adjusted for na

Electromagnetic compatibility
New technologies have been used to signi
-
ficantly reduce the interference levels ge
-
nerated by this frequency inverter.
The FR-F 740 EC conforms to the strict elec
-
tromagnetic compatibility regulations of
the European Union (EMC Directive, Envi
-
ronment 2). In order to meet these stan
-
dards the FR-F700 inverters are fitted with
a new, integrated interference suppression
filter, which can easily be deactivated with
a jumper if necessary.
You can also further limit the make current
and reduce network interference by fitting
the input of the inverter with an optional
AC reactor and a DC reactor, which is con
-
nected to special terminals on the inverter
unit.
The DC reactor is included as standard
equipment with models 00180 and above
andmustbeusedwiththem.
Circuit boards with two coats of pro
-
tective varnish
The frequency inverters with the E1 desig
-
nation (standard, type 02160 and above)
have circuit boards with two coats of pro
-
tective varnish.
This feature is available as an option for the
models up to type 01800. The twin coating
on the internal PCBs provides even better
protection against environmental influen
-
ces. This is particularly important in appli
-
cations sewage plants where the switchge
-
ar cabinets are exposed to aggressive
fermentation gases that can reduce the
service life of the equipment.
