H.1. Conditions of safe operations
Before tarting any work with the MFC1000 frequency converter read carefully thi U er manual.
Thi U er manual contain notice intended to en ure per onal afety, a well a to protect the MFC1000
frequency converter and connected equipment again t damage.
Ignorance or not knowing of the information contained in It can cause physica injury or death!
It can al o cau e damage to the MFC1000 frequency converter and connected equipment!
In the further part of this User manual, the MF 1000 frequency converter, to which this instruction applies,
will be also referred to as the “drive” or “converter”.
H.1.1. Warnings
Incorrect insta ation, usage, and maintenance of the drive can cause physica injury or death, or
damage to the drive and connected equipment!
R I S K O F E L E C T R I C
S H O C K!
The drive contains high vo tage when connected to mains vo tage!
Dangerous vo tage present inside the device for at east 10 minutes after disconnecting the power
supp y!
•In tallation, u age, and maintenance of the drive mu t be performed only by qualified per onnel.
•Don’t make any connection change when the drive i connected to the power upply.
•Before witching on the main power upply and control circuit voltage make ure the drive ha been
correctly in talled and all hou ing element have been properly a embled.
•It i forbidden to touch the drive' voltage terminal if it i connected to the power upply.
•After connecting the drive to the upply voltage, it internal component (without the control terminal )
are on the power upply potential. Touching the e component can cau e an electric hock.
•When the drive i connected to the upply voltage, dangerou voltage appear at it output terminal U,
V, W even when the electric motor i not running.
•Externally upplied control circuit may carry dangerou voltage even when the input power of the drive
i witched off.
•After di connecting the drive from the upply voltage, dangerou voltage till remain in ide the drive
due to the energy tored in the power circuit capacitor (DC-link circuit). It can cau e an electric hock!
The time required for elf-di charge of capacitor in an undamaged drive i u ually between 5÷15
minute (a higher power rating of the drive mean the longer time).
For thi rea on before tarting any work on the drive, the electric motor or the electric motor cable
alway wait at lea t 10 minute after di connecting all power upplie ource and make ure that a
voltage on a clamp i not pre ent.
Attention! The ack of the vo tage at the connection termina s does not ensure the ack of
dangerous vo tage in the interna DC- ink circuit of the drive!
•The drive i not adapted for u e in flammable or explo ive environment becau e it can cau e fire or
explo ion. U e uitable flameproof enclo ure .

H.1.2. Basic ru es
•Don’t connect main voltage to output terminal U, V, W.
•Don’t mea ure the voltage endurance of any unit drive .
•To mea ure the cable in ulation it i nece ary to di connect them from the drive.
•Do not try to repair the unit your elf. Any repair mu t be performed only by authorized ervice.
Any modification or elf-repair of the drive can cau e phy ical injury, death, or damage to the drive
and the connected equipment. Any attempt at unauthori ed repair will void any warranty.
•Don’t touch integrated circuit and any other part on the drive’ electronic board.
•Don't connect any capacitor to motor wire (e.g. intended for improvement of power factor).
•Don't mea ure output voltage of a converter u ing digital voltmeter without low-pa filter. The voltage
can only be mea ured correctly with an electromagnetic voltmeter.
•The drive i not de igned to operate with periodically witched on/off upply voltage.
•If the electric motor run at low peed (below 25 Hz), additional cooling of the motor i nece ary.
H.1.3. Operation ist
The operations applied at installation and the first start-up of the drive
1. After unpacking the converter, it i nece ary to check up vi ually the pre ence of damage which
could ari e during tran port.
2. Check whether the delivery i in accordance with the order - check the nameplate.
3. Check up the corre pondence between the condition in which the converter will be u ed and
condition of an environment for which it i de igned ( ection H.1.4).
4. In tallation of the frequency converter hould be made due to the principle of afety and EMC rule .
5. Perform the configuration of the converter in accordance with the chapter of thi manual.
H.1.4. Environmenta conditions
Degree of po ution
The econd degree of pollution ha been a umed during the de ign, at which there are normally only non-
conducting pollution. However, there i a probability of temporary conductivity cau ed by a conden ation,
when the converter i di connected from the voltage ource.
In ca e the environment in which the frequency converter will work contain pollution, which can influence it
afety, it i nece ary to apply appropriate counteraction, u ing, for example, additional ca e , air channel ,
filter etc.

In a frequency converter where to meet the emi ion requirement for Cla C3 the RFI filter i not required,
the po ibility of radio interference may be expected.
The inverters are not intended for use in the pub ic ow vo tage
network that supp ies residentia premises. Radio frequency
interference is expected when used in such a network.
In IT grid u age of a ymmetric filter of high frequency (capacitor Y) to reduce emi ion of
interference, ruin the concept of the di tributive grid i olated from the ground. Additional grounded
impedance can become threat of afety in uch y tem .
Before buying a drive for u e in an IT grid, plea e contact u to et the individual de ign of the y tem.
For technical rea on in ome application (current higher than 400A) fulfilling requirement of EMC i not
