Electric Safety
1.Before electricity is switched on, make sure earthing is properly done and wire and bat-
tery polarity are correctly connected.
2.When UPS relocation or wire reconnection is necessary, AC should be switched off and
UPS should be completely turned off, otherwise there might be a danger of electric shock
because output terminal might be still electried.
3.Please use PowerWalker specied appendix devices and accessories.
Battery Safety
1.Battery service lifetime will be shortened as ambient temperature rises. Replace batter-
ies periodically to guarantee normal UPS performance and sufcient back-up time.
2.Only personnel with proper expertise can carry out the maintenance of accumulator bat-
teries.

EN
3.Replacement of accumulator batteries requires a match of same type and model with
equal quantity.
4.As accumulator batteries may contain potential electric shock and short-circuit current
danger, to avoid accidents that might be thus resulted, the following warnings should be
observed during battery replacement:
A.Do not wear watches, rings or similar metallic items;
B.Use insulated tools;
C.Put on rubber shoes and gloves;
D.Do not place metallic tools or similar metallic parts on the batteries;
E.Switch off load connected to the batteries before dismantling battery connection termi-
nals.
5.Do not expose accumulator battery to fire in order to avoid possible explosion that
might endanger physical safety.
6.Non-professionals are not allowed to open or destroy accumulator batteries for elec-
trolytes in batteries contain strong acid and other dangerous substances which will cause
damages to both human skins and eyes. Should electrolytes come into any contact with
human body unintentionally, rinse with clean water and seek medical advice.
7.Do not cause battery positive and negative polarity short circuit otherwise electric shock
or inammation may occur.

Chapter 1 Brief introduction
1.1 Product introduction
PowerWalker VFI 3/3 Series products are high-efciency and high-performance, double-
conversion three phase input and three phase output UPS, unit capacity ranging between
20KVA-40KVA. Categorized by capacity, the products can be further divided into 20KVA,
30KVA and 40KVA. This series not only provides perfect solution for power source pro-
tection and successfully solves problems such as blackout, boost, brownouts, sags, decay-
ing, oscillation, high voltage impulse, voltage uctuations, surges, harmonic distortion,
disturbances, frequency fluctuation etc, but also enhances adaptability to complicated
working environments so that the application elds is well extended to computer equip-
ments, communication equipments and other controlling equipments with good adapt-
ability to complicated industrial environments as well. Therefore, The Series products can
be applied in a diversied multi-industries eld such as telecommunications, nancing,
transportation, government, manufacturing and energy sectors.
PowerWalker VFI 3/3 Series products are also capable of ECO mode. Under ECO mode,
UPS is powered by AC supply while in case of abnormal AC supply UPS will be sup-
plied by accumulator battery after conversion through inverter. As the energy conversion
efciency reaches as high as 98% under ECO mode when there is normal AC supply, the
energy saving effect of UPS is remarkable. Meanwhile, when UPS inverter is at start-up
mode but without power output, which is similar to hibernation mode, the inverter life
term can be largely extended. At normal AC supply, except that ECO mode displays a
relatively poorer power delivery quality compared to normal double conversion mode, it
is capable of satisfying the needs of most power-driven equipments in today’s AC network
incorporation.
Remark: under ECO mode, conversion time of 0ms mode is not guaranteed and it is ap-
plicable only to single machine.
The following symbols will be frequently used in this User Manual as well as in the pro-
cess of actual application, therefore, correct identication and understanding of their con-
notations prove necessary.
