3Modes of Operation
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.

511-Y01-U169-1-01
12
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 .
3rd1 Bypass Mode
In 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 in 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
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 in 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 sn’t 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 sn’t provid l ctronic short circuit prot ction lik in normal mod . If a short
circuit or 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.
Prolong d ov rloads may caus th th rmal/magn tic prot ction act. In this cas , all loads will b
d n rgiz d.
3rd2 Normal 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.

511-Y01-U169-1-01
13
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 in 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 in acc ptabl limits.
3rd3 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 in 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.

5Operatin Procedures
This chapt r d fin s th op rating proc dur s to b follow d to activat , d activat and manag th UPS.
Th instructions shall b appli d with th s qu nc , in which th y ar writt n.
5th1 Commissionin
Mak th conn ctions according to th installation s ction.
Switch th circuit br ak r on th input distribution pan l “ON” / “I”.
Switch th circuit br ak r on th by-pass distribution pan l “ON” /”I”.
Bring th inrush fus (F6) and input fus (F1) to “ON”/ “I” position.
Bring th by-pass circuit br ak r (F4) to “ON”/ “I” position.
Wait for th LCD to start up. S t th dat and tim .
S th “NORMAL” m ssag on th LCD.
Bring th circuit br ak r of th xt rnal batt ry cabin ts to “ON”/ “I” position.
Bring th batt ry circuit br ak r (F5) to “ON”/”I” position.
Bring th output circuit br ak r (F2) to “ON”/ “I” position.
“NORMAL” m ssag will not b display d, until th UPS starts up. 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.
5th2 Decommissionin
Bring th output circuit br ak r (F2) to “OFF”/”0” position.
Bring th input, inrush and manual by-pass circuit br ak rs (F1, F6 and F3) to “OFF”/”0” position.
If th by-pass mains input is s parat d, bring th by-pass circuit br ak r (F4) to “OFF”/”0” position.
Bring th batt ry circuit br ak r (F5) to “OFF”/”0” position.
In th v nt of an xt nd d p riod of UPS inactivity, th batt ri s must b charg d p riodically
in ord r to prolong batt ry lif . Th charg p riod, which d p nds on th t mp ratur , is giv n
in th “storag ” s ction of th manual.
5th3 Switchin into manual by-pass durin operation
Manual by-pass nabl s th op rator to isolat th l ctronic circuitry of th UPS from th mains and th
load without int rrupting th load op ration by conn cting th loads dir ctly to th bypass supply. This
f atur is us ful whil p rforming maint nanc or s rvic .
Bring th manual bypass circuit br ak r (F3) to “ON”/ “I” position.
Mak sur that th UPS switch s into bypass op ration. (Voltag , fr qu ncy and wav form of th bypass
mains shall b in limits, and bypass shall b nabl d for th UPS to op rat in bypass mod )
Bring th input and inrush circuit br ak rs (F1 and F6) to “OFF”/”0” position.
If th by-pass mains input is s parat d, bring th by-pass circuit br ak r (F4) to “OFF”/”0” position.
Bring th batt ry circuit br ak r (F5) to “OFF”/”0” position.
