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.

2. PARTS THAT CONSTITUTE THE SYSTEM

All the units are constituted by six functional operating sub-system:

-IGBT Rectifier (R)

-Inverter (I)

-Battery (B)

-Static Switch: Static Switch Inverter (SSI) e Static Bypass (SB)

-BKF optional (standard only for 400-500-600-800 kVA)

-Manual Bypass (MB) standard for 60-80-100-125-160-200-250-300kVA

mounted internal (can be also external), optional for 400-500-600-800kVA

mounted only external.

-Front Panel

For the description of the single parts, see: “UPS OPERATING MANUAL”

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.
