• This device serves as an uninterruptible power supply for connected loads. The device is in
compliance with all relevant safety regulations concerning information technology equipment, for
use in an office environment.
• Depending on the type and rating of UPS device, certain configurations of battery extensions may
be connected. These battery extensions may only be connected to the compatible basic UPS unit.
GeneralWarnings
WARNING: We consider the safety of personnel to be of paramount importance. For this reason it is
essential that procedures relating to safety in this manual be carefully reviewed before commencing work,
and properly adhered to thereafter. The User or Operator may intervene in the operation of the UPS
provided that the instructions laid out in the section titled “Installation” on page 6 are strictly followed.
WARNING: Even when all switches and/or circuit breakers are open, dangerous voltages are present
within this unit!
There are no user-serviceable parts inside. Only factory authorized technical personnel
may carry out any operation that requires protection panels to be opened and/or removed.Any repairs or
modifications by the user may result in out-of-warranty repair charges, unsafe electrical conditions, or
violation of electrical codes.
Safety Notices
WARNING: Read the following safety notices carefully! Disregard of these safety notes may endanger
your life, your health, and the reliability of your device and the security of your data.
• Transport the unit only in suitable packaging (protected against jolts and shocks).
• If the equipment is moved from a cold environment to a warmer operating location, condensation
may occur. Before you switch on the equipment it must be absolutely dry.An acclimatization period
of at least two hours is required.
• The equipment must be installed in accordance with the environmental conditions specified in
“Environmental Conditions” and in Table 2.
• Even with all buttons in “OFF” position the device (UPS) is not isolated from the mains. To isolate
completely from the mains, the power cord must be disconnected.
• This equipment services power from more than one source. The output terminals and/or receptacles
may have voltage present even when the unit is unplugged. UPS’s present a different safety issue
than most electrical equipment because unplugging the UPS puts it into backup mode. Unplugging
the UPS does not remove the electrical charge.
• In case of interruption of the mains voltage, the integrated battery maintains the power supply to the
user’s equipment.
• The power supply cord is intended to serve as the disconnection device. The outlet-socket must be
near the equipment and must be easily accessible.
• This UPS must be connected to an earthed mains outlet-socket.
• Place all cords so that nobody can stand on them or trip over them. When connecting the device to
the power supply, follow the instructions in the section titled “Installation”.
• Make sure that no objects (e.g. pins, necklaces, paper clips, etc.) get inside the device.
• In emergencies (e.g. damaged case, controls or power cables, penetration of liquids or foreign

Battery Safety
WARNING: The batteries installed in the UPS and within the battery extensions contain electrolyte.
Under normal conditions the containers are dry. A damaged battery may leak electrolyte that can be
dangerous in contact with the skin and cause irritation to the eyes. Should this happen wash the affected
part with copious amounts of water and seek immediate medical advice.
• Voltage is always present on the battery terminals.
• Even when discharged, a battery has the capacity to supply a high short circuit current, which, in
addition to causing damage to the battery itself and to associated cables, may expose the operator to
the risk of burns.
• Batteries should not be kept in storage for periods exceeding 6 months at 25°C without being
recharged (having been charged to 100% at the beginning of any such period). If these conditions
are not respected the performance of the battery can no longer be guaranteed. It is advisable to
recharge the batteries at least once every 4 months.
• Since new batteries often do not provide full capacity after an initial charge it may be necessary to
carry out a number of discharge/recharge cycles before optimum performance is achieved.
• In order to protect the environment, batteries must be disposed of in accordance with the regulations
governing disposal/recycling of toxic and harmful waste.
Repacking of Unit
Do not pack the equipment until at least two (2) hours have elapsed since the last recharge.
Place the equipment in bags made of a material sufficiently porous to allow it to breathe (e.g. 100µm
polyethylene).
Do not remove air from the packaging.
When packing unit for movement by common carrier, place in original, or equivalent packaging container.

Storage
If the UPS is to be stored prior to use, it should be stored in a clean, dry environment and away from
temperature extremes. It is recommended that the equipment be stored in a temperature controlled,
moderate humidity environment. Table 1 below provides the temperature and humidity storage limits:
NOTE: When storing equipment, every 8°C above 25°C reduces the shelf life of the battery by 50%. More
frequent battery charging is required to maintain the batteries in storage at these greater temperatures.
Environmental
Conditions
The UPS must be installed on a level and even surface and in an area protected from extremes of
temperature, water, humidity and the presence of conductive powder or dust (See Table 2 on page 6). Do
not stack units and do not place any objects on top of a unit.
The functional temperature range of the UPS is 32°F to 104°F (0°C to 40°C).
The ideal ambient temperature range is 60°F to 77°F (15 °C to 25°C).
Expected battery runtimes and battery life is based on operational temperatures between 68°F and 77°F (20°C
and 25°C). Operation of the equipment above 77°F (25°C) reduces the service life of the batteries dramatically.
Floor Loading
Taking into consideration the weight of the UPS, extension battery packs, and any other equipment that
may be mounted in an associated rack, confirm that the floor in the chosen location be capable of
supporting the weight of the combined units.
NOTE: Weights for the UPS and battery packs are shown in Appendix A, “Specifications”.
Ventilation
It is necessary to leave a minimum space of at least two inches (50 mm) in front and rear of the UPS to
allow a flow of air.
Electrical maintenance and servicing requires access to the front and back of the UPS. Provide the
necessary space to allow service personnel access to the UPS.

preparations
WARNING: Before connecting any input wiring to the UPS, take precautions to insure that all circuits
being used are the proper voltage and current required for the UPS. If this UPS is not used with the
supplied power cord, care must be taken to use properly rated cords (see “Appendix A: Features and
Specifications” on page 23) which comply with all regional and local codes.
WARNING: UPS output receptacles are energized when the front panel power switch is in the “ON”
position (green LED is illuminated).
WARNING: Electrical shock hazard: Even when the UPS is disconnected from the mains, hazardous
voltages may still exist at the output receptacles of the UPS. The UPS receives power from more than one
source – AC input and DC input from batteries. All input sources (AC and DC) must, therefore, be
disconnected before carrying out maintenance work inside the UPS.
Connections Battery Connections
WARNING: Before connecting a battery pack to the UPS, the circuit breaker of the battery pack must be
switched to “OFF.” After electrical connection with the UPS is established, the breaker must be switched
to “ON.”
NOTE: Each Battery Pack contains two battery connectors.The first battery pack is connected to the UPS
using the cable supplied with the pack. Each additional extension battery pack is connected by attaching
its cable to the previous pack

Fig. 8: Battery Circuit Breaker
Power Connections
After all external batteries are connected, make the necessary input and output power connections by
following the steps below.
1. Connect the input power cord to the AC outlet
NOTE: The batteries will immediately begin charging upon availability of input power.
2. Connect the load to the UPS.
It is suggested that the highest priority equipment be attached to the main outlets and that lower
priority loads be attached to the two programmable outlets.
NOTE: With the use of MopUPS
®
software or the ManageUPS
®
network adaptor, the programmable
outlets can be set to have a delayed start-up or a pre-scheduled shut-down during battery operation in
order to conserve battery power for the highest priority loads.
3. If using a UPS with IEC receptacles and inlets, cords may be secured by using the cord retainer and
supplied tie wraps, see Figure 7.
4. After all connections are made, follow the instructions in the section titled “UPS Start-up &
Shutdown” on page 15 to start your UPS and external battery.
Theory of
Operation
ATTENTION: This UPS is supplied with standard power cords and receptacles suitable for its use in
your area of operation. It may be installed and operated by non-technical personnel.
UPS Mode
In use, the UPS is connected betweenAC input power and the load. The operation of this UPS is based
on the on-line principle in which the inputAC power is first converted to DC, and secondarily converted
back to a sine wave of a fixed frequency and voltage to supply controlled power to the load. This UPS
topology is used to isolate the critical load (e.g. servers, switches, routers, etc.) from a variety of power
line problems, including the total loss of inputAC power.
Battery Mode
In the event of a mains failure, the maintenance-free batteries will continue to provide an uninterrupted
supply of energy to the load. In practice, most mains failures are of relatively short duration. Therefore,
the energy stored in the UPS’s batteries is, in most cases, sufficient to ensure continuous operation of the
connected systems until the mains power is reestablished. In the event of a long lasting mains failure, the
UPS can be utilized with shutdown software to enable a controlled shutdown of connected systems.
The most reliable method for determining the estimated battery runtime is the application of MopUPS
software or a ManageUPS network card. With this software, the estimated remaining battery capacity is
indicated before and during an AC power failure. These products also allow for automated shutdown
procedures that can shut down the attached devices after safely closing open application programs and the
operating system. After return of the mains voltage, the UPS automatically restores power to the
connected equipment.
Circuit Breaker

Theory of Operation
Sinergy S II Series Series UPS User Instruction Manual 11
Bypass Mode
In the event of a brief overload on the UPS or internal UPS failure, the load is immediately supplied directly
from the mains via an automatic internal bypass.As soon as normal status is reestablished, an automatic
switch over to inverter operation is performed.
• < 110% warning
• 110% - 130%: 12 seconds, switches to bypass
• >130% - 1.5 seconds, switches to bypass
Contact technical service for further details
Front Panel Display
