1. INTRODUCTION
The purpose of this manual is to guide the installer or user in the correct installation
of the parallel redundancy or power parallel system in the plant.
Before reading this manual, the user must carefully read the UPS
OPERATIONAL MANUAL and correctly follow the instructions for the individual
units, especially the safety requests according to CEI 64-8 and to 46-90.
The maker declines all responsibility for damages caused to persons or things,
deriving from the non-compliance of the above.

3. REDUNDANT PARALLEL SYSTEM
3.1 DESCRIPTION PARALLEL REDUNDANCY SYSTEM
The parallel redundancy system is constituted by “N” UPS (up to a maximum of 5+1
units), configurated as redundant parallel units. In the UPS The Manual Bypass is
external and optional, and generally is only one for all units.
In addition to the standard functions of a UPS such as power continuity, protection of
the load from mains distortions etc., the parallel redundancy system guarantees a
continuity of power even if more than one system failure is ascertained.
This is possible because all the units are constantly operative and feed the load in
parallel, furnishing each with a current equal to “total load /n”, where “n” is the number
of the units that are being supplied at that moment.
The automatic distribution control of the AC current equalizes the currents of the “n”
units and reduces the unbalance to less than 10%, under all load conditions.
The load is fed by the parallel inverters even when an instantaneous overload “n x
200%” of the nominal load of every individual unit is verified.
In the event of a breakdown of one of the units, the load is fed by the others. Only in
the event that ulterior breakdowns are verified in the other units will the load be
transferred to the Emergency Mains (Bypass).
3.2 OPERATIONAL STATUS PARALLEL REDUNDANCY
If a breakdown occurs for which a UPS can no longer distribute on the load, during
the state of “n UPS in normal functioning”, the parallel redundancy system gets
transferred to the “n-1 UPS in normal operational status. Under these conditions, a
further irregularity of a UPS which prevents the feeding of the load, transfers the system
to the “Emergency Bypass Line, feed the load” condition, every additional irregularity,
may or may not, according to the type of irregularity, interrupt the feed to the load. The
irregularies are registered by each UPS with alarms and visualized on the same front
panel of the UPS.
In the event that a system mode has a rectifier breakdown or mains loss, in the “n
UPS in normal functioning”, the UPS will continue to distribute the load discharging the
battery, automatically isolating itself from the system until the end of the back-up time
and transfers the system to the “n-1” UPS normal operating mode.
If the system is transferred to the Manual Bypass (MB), the load gets fed directly
from the mains, therefore not guaranteeing the continuity of the load and the entire
parallel system becomes separated from the load.

4. INSTALLATION PARALLEL REDUNDANT KIT
Before installing the redundant parallel system, follow carefully the “INSTALLATION”
chapter in the “UPS OPERATING MANUAL” for the individual units, to be aware of all
the information regarding:
-Reception of UPS
-Size and weight
-Distance from walls
-Cable sections, fuses and terminal board
4.1 SUPPLEMENTARY HARDWARE
In order to transform “N” standard “Individual” unit into a redundancy parallel system,
it is necessary to obtain a Parallel N kit.
Each Parallel Kit contains:
-N. 1 Parallel interface card PB214 Rev.B or Higher SLOT-PAR (Pict. 8)
-N. 1 Connection cable CAN (DB9-DB9) (Pict.8)
-N. 1 Parallel Kit Manual
Picture 8 – Contents of the package
4.2 FUNCTION
The parallel-kit enables UPS’s designed as single units to be modified for parallel
operation. This procedure describes the connection and configuration of the system.
The working steps in this manual and the Operation-Manual for Paralleling must be
followed to ensure the correct installation and setup of the system.
4.3 POSITIONING
It is advisable to place the two UPSs at a distance of at least 10 cm from each other
in order to facilitate the passage of power and signal cables.

4.4 INSTALLATION
This description contains all information for the installation of the PCB into a single
unit.
For changing a single UPS into a parallel operational UPS it is necessary to mount
the Interface PCB in the UPS and repeat all the steps for each unit being part of the
parallel system.
Before starting the work it is necessary to stop each UPS and/or put the load into the
Manual-Bypass-Mode. For this step please refer to the Operating Manual.
ATTENTION
We strongly point out that the load is not supplied with a secure power-supply when
using the Manual-Bypass, a mains blackout could lead to an interruption of the power-
supply to the load.
After transferring the load to the Manual-Bypass and stopping the UPS, verify the
flat-cable W30C is fixed on the slot-plate. Connect the cable W30C to the connector
CN1 on the SLOT-PAR-PCB and mount the card with the two screws in the slot of the
UPS (see picture 10).
For a proper communication between all UPS it is mandatory to terminate the CAN-
Bus by using 120 Ohm-resistors. This is done using jumpers on the first and last UPS’S
in the system.
Configuration of the jumper of the SLOT-PAR-PCB in function of the amount of UPS
used in the parallel system:

Picture 10 – Install the Interface and connect the cable
The connection between all units involved is done by the CAN-BUS cable supplied
with the kit.
Starting from the first unit, the cable is connected to “PAR CAN-OUT”. It goes to the
second unit “PAR CAN-IN”.
If more then two units are configured for the parallel-system, some additional cable
must be connected in the same sense: A second cable goes from the second unit “PAR
CAN-OUT” to the third unit “PAR CAN-IN” etc.
For Example: For 4 UPS, start the connection from UPS1 to the UPS2, from UPS2 to
the UPS3, then from UPS3 to UPS4 and finally from UPS4 return to the UPS1 making a
ring.
ATTENTION
Check accurately that the CAN-BUS cable is connected to the SLOT-PAR and not
other DB9 ports present on the rear of the UPS. A wrong connection may be result in a
damage of the interface card or/and the unit.
