SAFETY CONSIDERATIONS
The POWER+UPS system is designed for industrial applications and harsh
environments. Nevertheless the POWER+UPS system is a sophisticated power
system and should be handled with appropriate care, following these guidelines.
Do’s
•Read this manual carefully before starting installation and operation of the
UPS.
•Review the safety precautions described below to avoid injury to users or
damaging equipment.
•All power connections must be completed by a licensed electrician who is
experienced in wiring this type of equipment, and who is knowledgeable
about all federal, state, and local electrical codes and regulations. Improper
wiring may cause damage to the equipment or injury to personnel.
•Pay attention to the warning signs, labels and marks on the unit. A warning
sign signals the presence of a possibly serious, life-threatening condition.
•Keep the surroundings clean, uncluttered and free from excess moisture.
•Allow only qualified technicians to service the UPS. There are no user-
serviceable components. Do not try to repair it yourself!
•Use the UPS only for its intended purpose.
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
The battery drawer contains a series of 12-Volt batteries that provide high voltage
and
energy in the UPS body even when the UPS is not connected to the AC input.
Appropriate precautions should be taken during installation, inspection and
servicing.
Don’ts
•Do not open the cover of the UPS or the battery cabinets under any
circumstances. All UPS panels and doors should be closed.
•Do not insert any objects through the ventilation holes.
•Do not put objects on the UPS.
•Do not move the UPS while it is operating.
•Do not use the UPS outdoors.
•Do not turn the UPS upside down during transportation.
•Do not connect or disconnect the cable to the battery cabinet before the
battery circuit breaker is turned OFF.
•Do not turn ON the battery circuit breaker when the battery cabinet is
disconnected from the UPS.
•Do not install next to any gas or electrical heaters. A restricted location is
recommended in order to prevent access by unauthorized personnel.

OPERATION.THEREFORE,IT IS STRICTLY
FORBIDDEN TO CONNECT THIS SYSTEM TO
THE AC POWER SOURCE WITHOUT A NEUTRAL
(NULL)CONDUCTOR!!
FAILURE TO USE A NEUTRAL CONDUCTOR MAY
CAUSE PERMANENT DAMAGE TO THE SYSTEM.

1. INTRODUCTION
Thank you for purchasing a POWER+UPS system.POWER+ is the most
sophisticated UPS on the market today.
In general, an Uninterruptible Power Supply (UPS) provides backup power for use
when the utility AC electric power mains fail or drop to an unacceptable voltage
level. POWER+is a whole lot more.
POWER+ is designed to protect your data and equipment and minimize downtime
and other adverse effects normally incurred by power irregularities and failures.
POWER+ continually eliminates surges, spikes and sags that are inherent in
commercial utility power. Over time, these irregularities shorten the life of equipment
and components. The efficiency of POWER+thus helps to extend the life of your
equipment, even through normal use when the input power system is constant and
continuous.
POWER+ requires very little attention or intervention during normal operation;
however, you should read and understand the procedures described in this manual
to ensure trouble-free operation.
POWER+is a parallel redundant UPS and is flexible in structure, allowing it to be
easily extended by adding modules as required. The UPS modules are designed for
hot swapping, making many different configurations possible.
POWER+has many unique features:
•POWER+ is reliable thanks to its N+ 1 parallel redundancy.
•POWER+
is both flexible and modular; it may include from one to ten
modules.
•POWER+
is a true on-line battery design according to IEC62040-3.
•POWER+
is a "green" power solution thanks to THD of 5% at the input,
and provides “clean” power to your loads.
•POWER+
employs active current sharing at the input / output.
•POWER+
has an overall efficiency of up to 96% and backup efficiency of
98%.
•POWER+
is light and small, a 10kVA module weighs only 9Kg.

System Controller
The POWER+system controller has three purposes:
•to allow the user to manage and control the UPS as well as monitor the
parameters of all sections of the POWER+via the control panel
•to collect and summarize data from all sections of the UPS
•communication with external computers for data transfer and operation
The POWER+can work without the system controller but with reduced functionality.
UPS Module (10kVA / 8kW)
The UPS module is the core of the POWER+, which consists of from one to ten
identical modules in parallel depending on capacity requirements.
Each module includes a 3-phase charger with PFC1and a 3-phase PWM inverter
connected to batteries by a classic DC link. Each module is plug-in and weighs a
mere 9kg.
Static Switch (ST/SW) Module
The centralized hybrid Static Switch enables an automatic transfer of the load from
the output of the inverters to an alternate source whenever the inverter can no
longer supply power to the load. The static switch can transfer high currents at high
speed.
Battery
The POWER+battery bank is used as a backup in the event that the utility AC input
fails.
For systems from 10kVA through 30kVA, the batteries may be housed internally,
however for systems from 40kVA through 100kVA, or for sites where a long backup
duration is required, the batteries are housed in external cabinets next to the
POWER+cabinet.
Batteries are charged by the rectifier which supplies both the inverter and the battery
charger.
1PFC is a feature included that reduces the amount of generated reactive power. Reactive
power operates at right angles to true power and energizes the magnetic field. Reactive
power has no real value for an electronic device, but electric companies charge for both true
and reactive power resulting in unnecessary charges.
In power factor correction, the power factor (represented as "k") is the ratio of true power
(kWatts) divided by apparent power (kVA). The power factor value is between 0.0 and 1.00. If
the power factor is above 0.8, the device is using power efficiently. A standard power supply
has a power factor of 0.70-0.75, and a power supply with PFC has a power factor of 0.95-
0.99.

2. OPERATING MODES
The POWER+UPS functions to supply AC electrical power to your load.
While using the POWER+, three modes of operation are possible:
•Normal operation
•Battery operation
•Bypass operation
Normal Operation
The UPS is almost always in normal operation mode. The load receives its power
from the inverters that supply stabilized voltage, protected from spikes and
irregularities in the AC input. The AC input system feeds the charger which supplies
DC power to the inverter, while concurrently charging the batteries.
Battery Operation
During battery operation, the load continues to receive power from the inverters, but
the DC input to the inverter is taken from the batteries, instead of from the rectifier.
The batteries are galvanically connected by DC link to the inverter and the charger.
The DC inherently remains constant when the AC input supply drops out, without
any switching devices.
The duration of the battery operation is determined by the load demand and the
battery capacity.
Bypass Operation
During bypass operation, the load receives power directly from the AC input via the
static switch.
Whenever the inverters cannot provide power to the load, either due to an overload
or a short-circuit in the load, transfer to the AC input is automatic. As soon as the
problem is corrected, the load is transferred back to the inverter.

4. FIRST-TIME SETUP
Installation and Start-Up Sequence
Preparation
1. Prepare the proper infrastructure for the POWER+with adequate cables and
connections.
2. Prepare the POWER+for installation. Ensure all components and modules are
complete and securely fastened to their shelves.
3. Verify that utility AC power is disconnected and that all switches are OFF.
4. Connect the POWER+to the electricity mains according to the correct phase
sequence.
5. Connect the battery set(s) to the POWER+.
6. Re-check your connections.
7. Ensure that the maintenance bypass switch is set to NORMAL (OFF).
Operation
Note: Before first setting up the UPS, make sure that the load is not connected.
When applying power to the POWER+, the system automatically runs the startup
process without a need to press the On/Off button.
1. Turn the AC input and AC bypass switch ON and wait (for about 2
minutes) for the POWER+to initialize.
2. The start-up sequence will begin and the control panel will show the
following sequence. (The details will vary, depending on your
application.)
