The VFI1000QS is a true online double conversion UPS System providing the highest degree of
power protection for your load.
Blackouts
In the event of a power cut, the VFI1000QS
will seamlessly transfer to battery power.
This is true “no-break” with zero transfer
time.
Sags
Spikes
Under
Voltage
Over
Voltage
The output remains constant regardless of
what is happening at the input. Momentary
sags and spikes are effortlessly taken care of.
Prolonged under and over voltages do not
require the VFI1000QS to enter into battery
mode due to its wide input voltage window.
Noise
Transients
Harmonics
Distortions on the input mains voltage are
not transferred to the load. The load is
powered from the UPS inverter at all times,
which is “ReGenerating” a new AC power
waveform clean of any power contaminants
on the input.
Frequency
The VFI1000QS can be set to frequency
conversion mode, with a fixed output
frequency. This means that in situations
where the input frequency may be unstable,
for example when on generator power, the
load still receives the required voltage and
frequency.
The UPS is composed of mains input, EMI/RFI filters, rectifier/PFC, inverter, battery charger,
DC-to-DC converter, battery, dynamic bypass and UPS output.

These are represented by a graphic on the LCD:
The rectifier converts the incoming AC power into DC. In doing so, surge suppressors
and filters remove any noise and damaging surges. The rectifier is Power Factor Corrected
(PFC) which means the UPS presents itself as a purely resistive load, ensuring the UPS has no
detrimental effects on power quality elsewhere in the building. The rectifier performs two
functions. The first is to provide the DC for the inverter, and the second is to provide a charging
voltage (and current) for the battery.
The battery has two circuits connected to it. The first is the charger that has an
adjustable battery charge current to allow extra battery packs to be connected without
compromising on recharge time. The second is a DC-DC converter that converts the battery DC
voltage to the DC bus voltage to feed the inverter when running on battery operation.
The inverter converts the DC bus voltage into the AC output voltage. It is a high
frequency, highly efficient design that utilizes PWM driven IGBTs to create a pure sine wave
output via the output low pass filter. The output voltage is constantly monitored and adjusted
for differing load levels to maintain a highly stable output. The voltage can be adjusted
depending upon requirements.
See section 4.6 for details of operating modes and graphical representation on the LCD.
The VFI1000QS utilises Power Inspired’s propriety Advanced Speed
Control (ASC) cooling system. Utilising super quiet fans the fan
speed is set according to actual cooling requirements. Thus, at low
loads and temperatures the fans will run at low speeds making the
units practically inaudible. This makes the VFI1000QS suitable for
applications where the highest degrees of power quality and
protection are required but where unit silence is paramount.

Step 3
Make up the vertical
support brackets
Carefully position the UPS in the
support brackets. Pop out the LCD and
rotate into vertical orientation if
required.
Note the LCD should be
at the top.
1. The UPS should be placed on a flat surface. Place it in an area away from vibration, dust,
humidity, high temperature, flammable liquids, gases, corrosive and conductive
contaminants. Install the UPS indoors in a clean environment. Do not operate the unit
whilst still in its box or packaging.
2. Maintain an ambient temperature range of 15ºC to 25ºC for optimal operation. For every
2ºC above 30ºC, the UPS will need to be derated by 10% of nominal capacity at full load.
The highest working temperature requirement for UPS operation is 40ºC. Note
temperatures above 30ºC have a detrimental effect on battery float life.
3. It’s required to maintain a maximum altitude of 1000m to keep UPS normal operation at full
load. If it’s used in high altitude area, please reduce connected load. Altitude derating
power with connected loads for UPS normal operation is listed as below:

4. Ventilation:
The UPS is equipped with a fan for cooling. Therefore, place the UPS in a well-ventilated
area. It’s required to maintain minimum clearance of 100mm in the front of the UPS and
300mm in the back of the UPS for heat dissipation and easy-maintenance. Maintain
minimum clearance of 100mm in the bottom of the UPS to avoid dust ingress and adequate
air intake (Horizontal orientation only).
3.7.1. External battery connection
Follow the procedure in the external battery cab manual.
3.7.2. UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension
cords. The power cord is supplied in the UPS package. In the UK, circuit protection is provided
via the plug fuse, in other areas ensure that the circuit feeding the VFI1000QS has over current
protection in place not exceeding 16A (e.g. a circuit breaker).
Note: Check if the site wiring fault indicator lights up in LCD panel. It will be illuminated when
the UPS is plugged into an improperly wired utility power outlet (Refer to Troubleshooting
section).
3.7.3. UPS output connections
There are two kinds of outputs: programmable outlets and general outlets. Please connect
non-critical devices to the programmable outlets and critical devices to the general outlets.
During power failure, you may extend the backup time to critical devices by setting shorter
backup time for non-critical devices.
Note that the programmable outlet feature is an option in settings (Section 4.5 –09 ) and if
disabled the programmable outlets operate the same as the general outlets, and therefore you
can connect critical loads to both sockets.
Do not connect any power cord to the output of the UPS that is in excess of 10m. This is to
ensure compliance with EMC regulations.
