2.6 Operation
Before connecting equipment to the UPS outlet, you must perform the initial
configuration. Very important here is the output voltage going to the connected
equipment.
The UPS device contains an energy storage facility (battery), which means the
outlet can carry electricity even if the USP is not connected to a power supply.
To switch the UPS off completely, first, hold the OFF button for longer than 3
seconds and wait for the UPS to shut down. Next, disconnect the power supply
connector from the device. Make sure no liquids or foreign materials gain access to the UPS' interior. To protect the UPS, it is best to avoid lasting output
loads greater than 80%. The output load shown on the display is only a guide.
To determine the actual output load, extra measurements with a suitable device are necessary.
2.7 Handling Batteries
Attention! Danger of shock and burns
Batteries can produce electrical shock and short circuit currents that are
capable of burning tissue.
Keep unqualified persons away from batteries.
Do not place batteries in or around sources of heat, e.g. fire, because
they may explode!
Do not open or destroy batteries. The electrolyte is extremely hazardous
for persons and the environment (danger of burns to eyes and skin; poison).
MD Series 19
MD-1000I / MD-2000I / MD-3000I Safety Instructions

MD-1000I / MD-2000I / MD-3000I Explanation of USB Function
3. Explanation of USB Function
This manual will provide you with fundamental information about single-phase
online UPS systems, specifically how they function, use of the various functions and what you are to do in the event of malfunction. In addition, this manual contains information about transport, storage, handling and installation of
UPS systems.
Guidelines presented in this document solely concern UPS requirements. The
installation and personnel performing the installation are subject to applicable
national and local electrical codes and regulations. Modification to the contents
of this manual may be necessary from time to time to accommodate technical
changes. We have gone to great lengths to ensure the contents' accuracy and
ease of comprehension. However, we would be grateful if you notify us of any
errors or inaccuracies you find.
We accept no liability for errors in this user manual or consequential damages
resulting from those errors.
The UPS system (uninterruptible power supply) has been designed and built to
protect sensitive electrical equipment, such as computers, workstations, electronic money handling machines, important business devices, telecommunication systems, process controls, etc., against failure caused by poor power quality or power failure. Such sensitive systems require comprehensive protection
against electrical failure. Often, the failure may be caused by events outside
the system (e.g. thunderstorm, breakdown of operations) or interference
caused by nearby equipment (such as motors, air conditioners, machinery,
welding, etc.).
Power supply malfunctions are typically:
– Quick and slow line voltage peaks, fluctuation
– Power failures
– Fast or slow frequency peaks and fluctuations
– Power line interference or transients
The UPS s
ystem monitors the abovementioned power supply parameters and
protects the connected devices via suitable actions (e.g. switch over in the
event of power surges, over voltage or drops).
The UPS' mode of installation modifies easily from upright, using the provided
legs, to horizontal in a 19" rack and vice versa.
You'll find instructions for changing the installation mode in the chapter dedicated to this subject ( 3.3 Changing Installation Mode).
MD Series 22
MD-1000I / MD-2000I / MD-3000I Explanation of USB Function
The advanced in
sulated-gate bipolar transistor (IGBT) technology and industrial quality design ensure the UPS will operate efficiently and dependably,
even under tough conditions.
A powerful CPU integrates all the power stages, control and communication
functions required to provide maximum protection and UPS function, including
monitoring of the energy saving management, remote control and selfdiagnostics. The unit's cleverly designed CPU communication system permits
remote computer control with full functionality from any computer environment
via standard RS-232 port.
The UPS' wide input voltage tolerance (120V~288V) permits under or over
voltage correction without use of the battery, helping to extend the battery's
operating life.
The cold start function ensures the UPS will start even in the event of a power
outage.
A battery management system monitors the battery's charge to determine
when the battery draw will cease, another feature that prolongs the battery's life
span.
Advanced input voltage control minimizes the reactive power factor and increases efficacy. The unit's active power factor correction (PFC) delivers a
power factor (PF) of greater than 0.99, which translates into superb energy efficiency.
The adjustable bypass input voltage tolerance (low/high) prevents the unit from
switching to the bypass mode in the event of low or over voltage.
Large choices of output voltages (200/208/220/230/240) permit the use of different voltage systems.
This UPS device was designed and built to comply with international electromagnetic standards.

5.2 UPS Operating Mode - Normal
Normal UPS operation is as shown below:
Fig. 5-2 - 1 During normal power supply
The inverter converts DC into clean, stable AC. Output LEDs 2 and 4 light.
MD-1000I / MD-2000I / MD-3000I System Function
Abnormal UPS operation is as shown below:
Fig. 5-2 - 2 During abnormal power supply
If the power supply is abnormal, the UPS battery automatically transmits power
to the inverter, shuts off the charger and the AC-DC power converter (rectifier).
The inverter converts the DC to AC, in order to supply the connected equipment with uninterrupted energy.
As soon as the power coming from the supply returns to normal, the UPS
opens the AC-DC power converter (rectifier), shuts off the DC-DC converter
and turns the charger on.
During a power outage, the UPS operates as shown in ( Fig. 5-2 - 1 During
normal power supply). When battery level becomes too low, the audible alarm
signal begins and continues until the battery shuts down. The UPS automatically stops battery-supplied power when battery capacity reaches a certain limit
in order to prevent complete discharging. The UPS starts automatically when
the mains is again available.
MD Series 55
MD-1000I / MD-2000I / MD-3000I System Function
5.3 Overload
UPS operation when overloaded is as shown below:
Fig. 5-3 - 1 Overloaded situation
Generally, modern electronics and IT equipment produce inrush current when
they start. The magnitude of the inrush current varies depending on the equipment. Sometimes the current can be 6 times as high as measured capacity,
while other devices generate inrush that is insignificant.
The UPS has an overload protection that protects it from inrush current. If the
overload exceeds 105~120% of its capacity, it automatically switches to bypass
within 30 seconds, in order to protect the inverter. As soon as the overload
drops below <105%, the UPS returns to the inverter mode. If the UPS load exceeds 150%, the inverter automatically shuts down.
MD Series 56
MD-1000I / MD-2000I / MD-3000I System Function
5.4 Inverter
Fig. 5-4 - 1 Inverter malfunction
Output short circuit
If a short circuit occurs in the output while the connected equipment is receiving current from the inverter, the UPS automatically shuts down the inverter
and ceases supplying the equipment with power. LEDs indicate malfunction
and the audible alarm goes off. Once the short circuit has been remedied, the
UPS does not automatically start, but requires manual action to restart.
MD Series 57
MD-1000I / MD-2000I / MD-3000I System Function
MD Series 58
5.5 Inverter - Excessive Internal Temperature
Raised temperatures in the UPS automatically set off the bypass mode. The
UPS switches back over to normal operation, once the temperature has returned to normal. If excessive termperatures occur while the energy supply is
abnormal, the audible alarm sounds and the LEDs indicate malfunction. The
UPS ceases to supply the equipment with power.
If a power outage exceeds the duration of the UPS' power supply, the UPS will
shut down to protect the battery from deeply discharging. When the mains
comes back on, the UPS kicks back on, energises connected equipment and
controls the recharging of the battery/battery string.
The UPS has many outstanding features:
– Absolutely no interruptions or change in signal if a primary power source
outage occurs
– Pure sine wave output. The quality of the output voltage is significantly bet-
ter than that of the mains input.
– Processor-controlled bypass
– Input Power Factor Correction (> 0.95).
– LCD status and operating display
– Excellent Power Factor of 0.8
– Powerful and extensive communication interfaces
– RS-232 is standard
– USB is standard
– Programmable switch contacts are standard.
– NOT-HALT EPO contact is standard.

10. Maintenance and Service
With just a little maintenance, you will have the uninterrupted use of your UPS
system for a long time.
Please note that the dependability of the UPS is very much affected by its environment. Temperature and relative humidity must be kept at reasonable levels.
In addition, the area around the UPS should be kept as clean and dust-free as
possible.
At the optimum ambient temperature of 22° C, the typical battery life span is
approx. 4 years. Special-purpose, high-performance batteries will significantly
increase longevity, reaching around 8-10 years.
Regularly, (every 6-12 months), you should check to make sure the system
back-up capacity suffices for the intended purpose. If this is not the case, it is
necessary to replace the batteries.
10.1 Determining the Back-up Capacity
Before you begin this procedure, make sure all open documents and data
are backed up/saved. Also, be sure to inform all personnel who may be
affected.
There are two methods of determining the back-up capacity.
Method a)
is suitable for measuring the actual duration of time until the connected
equipment loses power.
Method b)
Permits determination of the remaining power capacity after a run using a
specified back-up time. Connected equipment usually does not lose
power in this instance.
To use one of these methods, it is necessary for you to simulate a situation that forces the UPS into battery back-up operation (e.g. turning off
building circuit breaker). Do not disconnect the power cable, as this will
break the earthing (neutral) connection. Once you have completed the
test, switch the circuit breaker back on and start the UPS as usual with
the ON button.
MD-1000I / MD-2000I / MD-3000I Maintenance and Service
Remember that after the test the batteries are low. The UPS system will need
to run several hours (min. 5 hr) on the mains before it reaches about 80% capacity.
If you fail to perform a battery back-up test regularly, we suggest, for the sake
of prevention, replacing the batteries every two years in order to safeguard the
availability of your system against failure caused by battery degradation.
