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.
The POWER+ RM 50 KVA model (RM stands for "rack mount") fits into a standard 19” wide
enclosure.
1.1 POWER+has many uniquefeatures:
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 10 kVA module weighs only 9 Kg.

1.2 Ac input/output main terminals
The main input and output terminals are located at the lower rear of the unit. The exact location
and arrangement of the main input and output terminals depends on whether your system
includes the optional maintenance bypass switch.are used to connect the AC input and bypass
inputs, the battery, and the AC output. See Figure 1 above.
1.3 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.
1.4 UPS module (10 kVA / 8 kW)
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.
1.5 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.
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 reactive 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.

1.6 Battery
The POWER+battery bank is used as a backup in the event that the utility AC input fails.
Depending on customer preference, batteries may or may not have been supplied with your
system.
The batteries are usually housed internally; however, for sites where a longer backup duration is
required, the batteries can be housed in an external cabinet or cabinets next to the POWER+
cabinet.
Batteries are charged by the rectifier which supplies both the inverter and the battery charger.
Free air circulation around the batteries is extremely important for proper battery safety. If
the Power+ is installed in a cabinet, the cabinet must have sufficient ventilation openings
to permit free air circulation around the batteries.
This means that solid glass or acrylic-type door panels are not suitable for a cabinet

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
2.1 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.
2.2 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.
2.3 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.
2.4 Maintenance bypass (option)
Maintenance bypass is an optional feature. In maintenance bypass mode, the UPS output
terminals continue to supply power to the load, but the interior of the UPS is isolated from all
power flows. This enables a maintenance technician to safely work on the UPS without any
interruption of power to the load.
For more information on the maintenance bypass feature, see section 11.
