When internal batteries UPS models are not enough for the acquired backup time because higher capacity battery
is required, the use of A type cabinets is necessary. These cabinets are designed to house different type and
quantity of batteries, so that the installation must be done in the final location.
Follow carefully the steps below:
•Make sure that the UPS is completely switched off and disconnected from the mains supply before
adding the batteries.
•Check the voltage of each battery.
•Assemble the battery cabinet(s) in accordance with the instructions included with the cabinet. Remember
to leave a minimum distance of 500mm between a lateral panel of each battery cabin and the obstacles
there may be around the battery cabinet. In this way, assembly and maintenance of the batteries are
easier.
•Install the breaker in accordance with the instructions included with the battery cabinet and check it is
open.
•Place and wire the batteries distributed over the cabinet divisions in accordance with the included battery
assemble drawing.
•Connect the battery cabinet(s) to the corresponding UPS terminals.

4OPERATION OF ZGR TOWER PRO 6 10 KVA
The operation is simple; the user only needs to read the manual and follow the operation instructions listed in this
manual no need any special training.
4.1 Start up and turn off UPS
The ZGR TOWER PRO 6 10 KVA is a double-conversion on-line UPS that can operate in the following
alternative modes:
Normal mode
The rectifier/charger derives power from the AC mains and supplies DC power to the inverter while floating and
boosting charge the battery simultaneously. Then, the inverter converts the DC power to AC and supplies to the
load.
SAI
Battery
cabinet
WARNING
Battery type, aging or manufacturer should not be mixed. If you want to increase UPS autonomy or replace
batteries, contact ZIGOR customer service and follow our recommendations.
PRECAUCIÓN
Verifique que la suma de potencias de carga no superen el valor nominal del SAI para prevenir la alarma de
sobrecarga.
ZGR TOWER PRO 6 10 KVA
Operation manual

17
Battery mode (Stored Energy Mode)
If the AC mains input power fails, the inverter, which obtains power from the battery, supplies the critical AC load.
There is no power interruption to the critical load. The UPS will automatically return to Normal Mode when AC
supply recovers.
Bypass mode
If the inverter is out of order, or if overload occurs, the static transfer switch will be activated to transfer the load
from the inverter supply to bypass supply without interruption to the critical load.
In the event that the inverter output is not synchronized with the bypass AC source, the static switch will perform
a transfer of the load from the inverter to the bypass with power interruption to the critical AC load. This is to avoid
paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than an
electrical cycle e.g. less than 15 ms (50 Hz) or less than 13,33 ms (60 Hz).
ECO Mode
When the UPS is at AC Mode and the requirement to the load is not critical, the UPS can be set at ECO mode in
order to increase the efficiency of the power supplied. At ECO mode, the UPS works at Line-interactive mode, so
the UPS will transfer to bypass supply.
When the AC is out of set window, the UPS will transfer from bypass to Inverter and supplies power from the
battery, and the LCD will show all related information on the screen.
Parallel redundancy mode (system expansion)
To achieve a higher capacity and / or increase reliability, the outputs of up to 4 UPS modules can be programmed
to operate in parallel. The built-in parallel controller in each UPS ensures automatic load sharing.
In case of one module fail, the other modules assume the power and loads could be run protected.
This is a great advantage compared to single UPS system, because in case of single UPS failure whole system
goes to bypass mode, and loads will not be protected from mains variations.
Please, check how much power needs to assumed by whole running parallel system in order to determine
maximum UPS quantity, and prevent to overload situation in case of module failure.
Parallel function setup
A group of paralleled modules behave as one large UPS system but with the advantage of presenting higher
reliability. In order to assure that all modules are equally utilized and comply with relevant wiring rules, please
follow the requirements below:
1) All UPS must be of the same rating and be connected to the same bypass source.
2) The Bypass and the Main input sources must be referenced to the same neutral potential.
3) The outputs of all the UPS modules must be connected to a common output bus.
4) The length and specification of power cables including the bypass input cables and the UPS output
cables should be the same. This facilitates load sharing when operating in bypass mode.
The basic installation procedure of a parallel system comprising of two or more UPS modules is the same as that
of single module system. The following sections introduce the installation procedures specified to the parallel
system.

Parallel installation steps as below:
1) Connect the UPS with parallel cables.
Fig. 4-1 Parallel connection
2) Connect all the outputs of the parallel UPS using individual breakers to one patch board before connect to
the loads. See the Fig. 4-1 as follows.
3) Adjust each UPS settings through LCD. See the Manual Chapter 4.3.1; 4.3.10; 4.3.11; 4.3.12.
A. Each UPS must be configured individually.
B. Set relevant parameters as below：
①Working mode: set as Parallel operation;
②Parallel ID: set different UPS ID one by one;
③Parallel amount: set the amount of UPS in parallel.
C. Power OFF UPS and continue with next unit.
4) Now close output breakers to make work in parallel mode
5) Once all UPS was configured, make sure all connections and wire sequence are correct, and then can be
powered ON at same time or one by one.
Parallel cable installation
Shielded and double insulated control cables available must be interconnected in a ring configuration between
UPS modules. The parallel control board is included on each UPS module. The ring configuration ensures high
reliability of the control.
WARNING
When the UPS in parallel, the input can be the same or different, but the output should be paralleled to one
patch board.
WARNING!
Make sure the N, L lines are correct, and ground is well connected.

Bypass mode in parallel working mode
Under normal Online working mode for all parallel UPS, following information could be show on LCD display. Two
UPS in parallel mode..
Two UPS working normally in parallel Online mode
ESC/OFF button must be push on each UPS to stop inverter mode.
①Each UPS will stop and disconnect inverter circuit;
②Rest of UPS will asume total load;
UPS 1 in Online mode
UPS 2 inverter stopped
The last UPS to be stopped will force whole system to transfer to bypass mode simultaneously
Two UPS transfered to bypass mode
To return to normal inverter mode, reverse procedure must be done pushing ENTER/ON on each UPS
NOTE: Pay attention because full load power could be assumed by only one UPS, and in this situation overload
alarm will appear.
4.2 Initial start-up
Connection with Utility
Do not disconnect the mains cable on the UPS system or the building wiring outlet (shockproof socket outlet)
during operations since this would cancel the protective earthing of the UPS system and of all connected loads.
The UPS system features its own, internal current source (batteries). The UPS output sockets or output terminals
block may be electrically live even if the UPS system is not connected to the building wiring outlet.
PRECAUTION
Make sure grounding is properly done.
