WARNING: POWERVAR considers the safety of personnel to be of paramount importance. For this
reason it is essential that procedures relating to safety be studied 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 “Batteries” on page 3 and “Button Operation” on page 17 are adhered to.
· The “Installation” of the UPS, described in “Electrical Preparations for UPS Installation” on page 11,
may only be carried out by qualified technical personnel.
· Even when all switches and interrupters are open, hazardous voltages are present within the UPS;
any operation that requires protection panels to be opened and/or removed must be carried out by
POWERVAR authorized technical personnel only.
· The Sinergy III Rackmount Series UPS listed in Table 1 on page 4, with a mounting height of 3 U
(1 U = 1.75” (44.45 mm), are designed for horizontal installation in 19-inch racks of Industrial strength.
1-3-2. Safety Notices
WARNING: Carefully read the following safety notices! Failure to observe the instructions may
endanger your life, your health, the reliability of your device or 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 the operating room, 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” on page 6 and in Table 4 on page 11 . Install the UPS indoors, and in a
structurally sound area.
· Even with all buttons in “OFF” (see “Button Operation” on page 17 ) the device
(UPS) is not isolated from the mains. To isolate completely from the mains, the power cables must be
disconnected.
· Lay all cables so that nobody can stand on them or trip over them. When connecting the device to the
power supply, follow instructions in the section “Electrical Preparations for UPS Installation” on
page 11.
· Make sure that no objects (e.g. pins, necklaces, paper clips, etc.) fall inside the device.
· In emergencies (e.g. damaged case, controls or power cables, penetration of liquids or foreign matter)
switch off the device and contact the appropriate customer service representative.
· Do not connect equipment that will overload the UPS (e.g. laser printers or vacuum cleaners) or
demand DC-current (e.g. half-wave rectifiers).
· When cleaning the unit, follow the instructions in the chapter “Maintenance” on page 35.
· The sum of the leakage currents (protective conductor current) of the UPS and the connected devices
may exceed 3.5 mA for ratings of the UPS. Earth connection is essential before connecting supply.
Connect your UPS power module’s grounding terminal to a grounding electrode conductor.
·Data transmission lines should not be connected or disconnected during a thunderstorm.

3
·The UPS is connected to a DC energy source (battery). The output terminals may be live when the UPS is
not connected to an AC supply.
·Emergency Power Off (EPO) input is located on the rear of the unit (see Figure 11 on page 13). When this
connection is open, the logic circuit will immediately shut down the UPS output.
· When mounting the unit in a rack, it has to be hooked on both sides and the front plate of the unit has
to be fixed to the rack by screws. The unit has to be fixed in horizontal position.
· Do not install the UPS near magnetic storage media, as this may result in data corruption.
· The vents for air intake and outlet at the front and rear side must not be obstructed. Leave adequate space
around all sides of the UPS for proper ventilation.
· Do not mount the unit with its front or rear panel facing down (at any angle). Mounting in this manner
will seriously inhibit the units internal cooling, eventually causing product damage not covered by
warranty.
1-4. Emergency
WARNING: The supply to the load may be operated by opening all the switches.
WARNING: DO NOT USE WATER to extinguish any fires that may occur in the area in which the UPS
is installed.
1-5. Leakage Currents
WARNING: Connect the earth ground [protection earth (PE)] safety conductor before any other cables
are connected.
1-6. Radio Interference
Sinergy III Rackmount is a class A product. The UPS device may cause radio interference. Do not place it near
devices which are especially susceptible to electromagnetic interference (e.g. transmitters/receivers, radar, metal
detectors, anti-theft devices).
1-7. Batteries
Battery maintenance must be carried out by authorized personnel.
· The batteries installed in external battery cabinets may contain electrolyte. Under normal conditions the
containers are dry. A damaged battery may leak electrolyte which can be dangerous in contact with 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 contacts.
· Even when discharged a battery has a 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.

4
·The voltage of a single cell of a single battery block is not dangerous. However a number of cells or
battery blocks, connected in series, can produce hazardous voltages.
· The battery is a “hermetic” type battery and must not be kept in storage or disuse for periods exceeding 6
months at 68°F (20°C) without being recharged ( having been charged to 100% at the beginning of any
such period). If this period is exceeded it is essential that the batteries be recharged, which requires that
the UPS be switched on. If these conditions are not respected the performance of the battery can no l
longer be guaranteed. We advise recharging 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 of toxic and harmful waste.
1-8. Repackaging
To re-pack, proceed as follows:
1. Do not pack the equipment until at least six hours have elapsed since the last recharge.
2. Place the equipment in bags made of a material sufficiently porous to allow it to breath (e.g. 100µm
polyethylene).
3. Do not remove air from the packaging.

3. OPERATIONS
3-1. Operating Mode/Status Description
Mode/Status Description
UPS Power On When UPS is powered on, it will enter into this mode for a few seconds for initializing
the system.
AC Mode When the input voltage is within acceptable range, and the UPS is turned on (the in-
verter is running), the UPS will provide pure and stable sine wave AC voltage. The
UPS will also charge the battery in AC mode.
Converter Mode When input frequency is within 46 to 64Hz, the UPS can be set with a constant output
frequency (50 Hz or 60Hz) through the inverter. The UPS will still charge battery at
this mode. There is no bypass at this mode.
Battery Mode When the input voltage is out of the acceptable range or power failure, and the UPS is
turned on (the inverter is running), the UPS will backup power from battery.
Bypass Mode When input voltage is within acceptable range and the bypass is enabled, and the UPS
(inverter) is not turned on or the inverter can’t support the load, the UPS will supply
power to the load through bypass.
Battery Test Mode When the UPS is in AC mode or Converter mode, and the battery test command is
enabled through LCD or monitoring software, the UPS will start Battery test. This
operation is used to check the battery status.
Warning Status If some error occurs in the UPS (but is still running normally), the buzzer will alarm
and warning code will appear in the LCD for trouble shooting.
Fault Mode When fatal error occurs in the UPS, it will beep continuously and go to fault mode.
It will display fault codes in LCD.
