3Modes of peration
Th r ar thr op ration mod s, which diff r in th path of th n rgy flow.
UPS block diagrams and th n rgy flow path in ach op ration mod is shown b low:
Wh n UPS has no s parat bypass mains input, bypass lin is also f d from th mains input. Thus, if such
a d vic is in qu stion, mains input shall b compr h nd d wh n th bypass mains input is r f rr d in th
following s ctions of th manual.
UPS b havior at th start-up is diff r nt from th usual op ration. Th UPS can only op rat in bypass
mod during start-up. So, in ord r for th UPS to start-up, fr qu ncy/wav form/rms valu of th bypass
mains voltag shall b in acc ptabl limits and bypass shall b nabl d.

13
Aft r start-up, th following appli s:
Op ration mod d p nds on th priority, inv rt r, r ctifi r and bypass pr f r nc s mad by th us r and
mains, s parat by-pass mains and batt ry voltag s.
Priority and inv rt r, r ctifi r and bypass pr f r nc s can b s t by using th COMMANDS and xtra
commands (EXTCMNDS) m nus.
If op ration in any of th s mod s is impossibl , output voltag will not b pr s nt. In this cas , loads will
not b f d, and “VSECFLR” m ssag is shown on th LCD inst ad of op ration mod .
3.1 Bypass Mode
D vic s without s parat bypass mains input, n rgy is drawn from th mains. In d vic s with s parat
bypass mains input, n rgy is drawn from th s parat bypass mains.
Loads ar f d via static bypass lin .
Output voltag has th sam amplitud , fr qu ncy and wav form as th input voltag .
Curr nt drawn by th loads ar only limit d by th th rmal/magn tic switch s ov r th n rgy flow path.
Voltag , fr qu ncy and wav form of th bypass supply shall b within th ir tol ranc limits, and bypass
shall b nabl d for th UPS to op rat in this mod .
Wh n th upp r provisions ar m t, th UPS works in bypass mod in th following conditions:
During th start-up
If th bypass priority is s l ct d
If th inv rt r is disabl d or block d
In cas of a prolong d ov rload
EC Mode
You can sav n rgy by s l cting th bypass priority. Effici ncy in bypass mod is high r than th
ffici ncy in normal mod . If th bypass priority is s l ct d, th UPS will op rat in bypass mod
wh n v r th fr qu ncy/wav form/rms valu of bypass mains voltag is within th ir tol ranc limits. If
th bypass voltag go s b yond th s limits, th UPS switch s into normal op ration.
Bypass mod do s not provid p rf ct stability in fr qu ncy/wav form/rms valu of th output
voltag lik in normal mod . Thus, th us of this mod should b car fully x cut d according to
th l v l of prot ction r quir d by th application.
Bypass mod do s not provid l ctronic short circuit prot ction lik in normal mod . If a short
circuit occurs on th output during bypass op ration, th th rmal/magn tic prot ction will act
and all loads will b d n rgiz d – load will b stopp d.
Prolong d ov rloads may caus th th rmal/magn tic prot ction to act. In this cas , all loads will
b d n rgiz d – load output will b stopp d.

14
3.1Normal Mode
En rgy is drawn from th mains input.
Loads ar f d via th r ctifi r and th inv rt r. Th AC voltag at th input is conv rt d to a DC voltag
by th r ctifi r. Th inv rt r conv rts this DC voltag to an AC voltag with a stabl sinusoidal wav form,
amplitud and fr qu ncy.
Output voltag is sinusoidal and has a r gulat d amplitud and fr qu ncy. It is ind p nd nt from th input
voltag .
Th inv rt r is synchroniz d in fr qu ncy with th bypass mains input to nabl load transf r to th
bypass supply without any int rruption, in cas of an ov rload or inv rt r failur .
Voltag and fr qu ncy of th mains input shall b within th ir tol ranc limits, and both th r ctifi r and
th inv rt r shall b nabl d for th UPS to op rat in this mod .
Wh n th upp r provisions ar m t, th UPS works in normal mod in th following conditions:
If th inv rt r priority is s l ct d.
If th bypass priority is s l ct d but bypass is disabl d or fr qu ncy/wav form/rms valu of
bypass mains voltag is not within acc ptabl limits.
3.1 Battery Mode
En rgy is drawn from th batt ri s. Loads ar f d via th inv rt r.
Output voltag is sinusoidal and has a r gulat d amplitud and fr qu ncy. It is ind p nd nt from th
batt ry voltag .
Batt ry voltag shall b within acc ptabl limits and th inv rt r shall b nabl d for th UPS to op rat in
this mod .
Wh n th upp r provisions ar m t, th UPS works in batt ry mod in th following conditions:
If r ctifi r is disabl d.
If th r ctifi r is disabl d or fr qu ncy/wav form/rms valu of mains voltag is not in acc ptabl
limits.
