• After about 30 seconds, the inverter and rectifier of the UPS
or each UPS will be running, but not supplying output voltage
because their respective switches (Q2) of the equipment and
panel board are still turned off.
In parallel systems, the first UPS starting the inverter will be the
one set as «Paral. Mst. Byp», the one with the highest address as
«Paral. Slv. By.Rsv» and the rest ones, if any as «Paral. Slv. By».
Logically, in parallel systems of two UPS units there will not be
any «Paral. Slv. By».
• Parallel equipments only.
To check the hierarchy of the UPSs (parallel status), is
needed to go back to main screen in each equipment (press 3
times (ESC)) and access to screen 0.1 in all of them (press once
() key), see Fig. 44:
UPS: Normal, Invert.
CFG: Paral. -------
Where:
ˆ First row corresponds the UPS status.
ˆ And the second to the UPS hierarchy relating to the rest of
the system, which is dynamic depending on the status of
the rest of the equipments:
– «Paral. Mst. Byp» bypass Master of the parallel system.
By default, the first UPS starting up the inverter ac-
cording to the established procedure.
– «Paral. Slv. By.Rsv» reserved bypass Slave. Initially cor-
responds to the equipment with the highest address ex-
cepting the one from «bypass Master». In case of failure
of the Master, it will take its functions.
– «Paral. Slv. Byp» bypass Slave of the parallel system
(systems with more than two equipments only). It will
become as «reserved bypass Slave», when it practise
as «bypass Master». In systems with more than three
equipments in parallel, the hierarchy of «reserved by-
pass Slave» will be taken by the one with the highest
address among the «bypass Slave».
– «Paral. Mst. Volt» voltage Master of the parallel system.
By default, the first UPS on normal operating (inverter in
operation), that the output switch (Q2) is turned «On».
– «Paral. Slv. Vt.Rsv» reserved voltage Slave of the par-
allel system. Equipment on normal operating (inverter in
operation), that the output switch (Q2) is turned «On»
in 2nd place or subsequently (after the «Paral. Mst.
Volt» or «Paral. Mst. Vt.Rsv»). Initially, it corresponds to
the equipment with the highest address, excepting the one
from «Voltage Master». In case of failure of the Master,
it will take its functions.
– «Paral. Slv. Volt» voltage Slave of the parallel system
(systems with more than two equipments only). Equip-
ment on normal operating (inverter in operation), that
the output switch (Q2) is turned «On» in 2nd place or
subsequently (after the «Paral. Mst. Volt» or «Paral. Mst.
Vt.Rsv»). It will become as «reserved voltage Slave»,
when it practise as «voltage Master». In systems with
more than three equipments in parallel, the hierarchy of
«reserved voltage Slave» will be taken by the one with
the highest address among the «voltage Slave».

• Turn «On» the output switch or switches of the panel board, de-
pending if it is single equipment or parallel system.
• Turn the output switch (Q2) of the UPS or each UPS «On».
The equipment or parallel system supplies voltage to the output
terminals of the switchgear panel board.
• Make sure that the inverter on LED indication (c) lights (green),
and bypass LED (b) is turned OFF in all UPSs (see Fig. 42).
If the status of the LEDs is wrong, please contact with the
T.S.S. (Technical Service & Support).
• For equipments with external battery cabinet, turn the switch-
fuse holder of the battery cabinet or cabinets (Q8) of each UPS
to position «On».
DO NOT TRY to make this manoeuvring at any
other time and/or in other way, because this oper-
ating could damage the equipment and/or cause acci-
dents.
• Once the rectifier is completely working, a process of equaliza-
tion (DC bus voltage starts to be equalized with battery voltage)
will be started. After a few seconds (depending on the battery
level), an alarm message like this will be displayed...
BATT. SWITCH OPEN
SWITCH IT ON
... it shows that the equalising process has been finished and AT
THIS MOMENT ONLY is when the battery switch, the battery pro-
tection or both elements can be turned «On»:
ˆ Equipments with a single battery mechanism, either the
battery fuse holder switch or the battery switch and la-
belled in the figures of the present document as (Q3). Turn
it «On».
ˆ Equipments with two battery mechanisms, fuse holder
switch (F3) and switch (Q3).
1. Turn the battery fuse holder switch (F3) «On» first.
2. Next, turn the battery switch (Q3) «On».
In parallel systems, repeat this process in each equipment.
DO NOT TRY to make this manoeuvring at any
other time and/or in other way, because this oper-
ating could damage the equipment and/or cause acci-
dents.
• If the equipment or parallel system has an outgoing distribution,
turn its switches «On».
• Start up the loads to be supplied in a progressive way. The joint
is started up completely, and the loads are protected through
the UPS or UPS parallel system.
• After the first start up, the usual start up/shutdown op-
eration of an equipment or parallel joint will be done by
means of the keypad of the control panel (PC). In parallel systems,
will be needed to act over one of them only.
Consider that the UPS or system will still be supplying
output voltage, it does not matter the status of the own
inverter or inverters:
ˆ Shutdown, from static bypass.
ˆ Started up, from inverter (On-line mode).
ˆ Started up, from static bypass (on Smart ECO Mode).
