2.0 Remarks about Safety
In order to keep safe in using the UPS, please comply with the following:
•Please charge the battery at least 24 hours before the UPS is in operation.
•After the battery is discharged or over three months without operation, the battery
should be charged immediately for at least 12 hours, ensuring the battery is full
and avoiding any unnecessary damage of the battery.
•The UPS is specially designed for computer only and it should not be connected
with any inductive or capacitive load, like electromotor, daylight lamp, laser printer,
etc.
•The UPS is not suitable for being used in life support systems, because it may
have some problems and bring trouble to the life support systems. The
responsibility will be users', if they insist on using the UPS in life support systems.
•It is normal that the temperature of the UPS surface reaches up to 50℃when it is
in operation.
•When AC fails and the “ON” button on the front panel is pressed, the UPS will
output voltage; if the “OFF” button on the front panel is pressed, the UPS will not
output voltage.
•It is forbidden to open the case, because there is danger with electricity. If there is
problem, please handle with the instruction of experts.
•It is forbidden to put container containing liquid inside on the UPS, because it will
cause danger of electric shock or fire when the UPS short-circuits.
•When the UPS is abnormal, please cut off power immediately and turn to experts
or the dealer for help.
•As there is no overload protection of the UPS, it cannot be overloaded. Otherwise,
it would cause danger.
•It is strictly forbidden to place and operate the UPS in the following environment：
oPlace with inflammable gas or corrosive gas or much dust；
oPlace with very high temperature or very low temperature(above 42℃or
below
o0℃) or high humidity(above 90％) ；
oPlace with direct sunlight or near heater；
oPlace with strenuous vibration；
oOutside
•Please use dry powder fire extinguisher in case of fire; it is forbidden to use fluid
fire extinguisher because it will cause electric shock.
•Please put the socket near the UPS, in this way, it is convenient to disconnect the
socket and cut off power in case of emergency.
Attention! Please ground the UPS for safety purpose

3.0 Working Principle
3.1 In AC mode
When UPS is in normal working mode, AC goes through the filter and the harmful
waves are filtered. After that, AC charges the battery and meanwhile, passes UPS
AVR and the filter and provide power for the equipment.
3.2 AC Failure
When AC fails, the battery will supply power to the inverter and then passes filter and
provide power for the equipment, ensuring the continuous power supply.
3.3 Connections of the UPS
The UPS has the following connections:
•1 RS232 serial port (only for EM3941 and EM3942)
•1 USB port
•1 AC connection (Power input) (only for EM3942)
•Output connections (the number differs per model)

6|ENGLISH
3.4 Battery and Charging:
•When the UPS is connected to AC, the charger will charge the battery fully in
about 10 hours.
•When the battery is used up, please turn off the UPS and charge the battery for a
least 10 hours when. Then turn on the UPS
4.0 Main Features
4.1 Unattended Operation
•Please connect the UPS to AC and press the ON button on the front panel, the
UPS is turned on and the AC outputs stabilized voltage.
•When AC fails, UPS will supply power to the equipment immediately. And when
the battery is used up, UPS will turn off automatically.
•When AC comes back, UPS will turn on automatically.
4.2 Protection
•Battery discharge protection: when the battery discharges and the UPS is in
inverter mode, the UPS will check and monitor the working status of the battery;
when the battery voltage drops to the limited lowest voltage, the inverter will turn
off automatically and protect the battery; When AC comes back, the UPS will
turn on automatically.
•Short-circuit Protection: when the UPS is in inverter mode and there is shock or
short-circuit, UPS will output limited currency, protecting the UPS( When in AC
mode, the UPS will be protected first by input fuse and then transfers to the
inverter working mode).
4.3 Four Kinds of Alarm Function
•When AC fails, and the UPS supplies power, UPS will alarm once every 10
seconds and the beep stops about 40 seconds later.
•When the battery is nearly used up, the UPS will alarm automatically and the
beep frequency is once every 1 second.
•Overload, when the UPS is overloaded, UPS will alarm once every 0,5 second
•Fault, if there is a faulty operation of the UPS, UPS will alarm continuously.
4.4 Lock Phase Function
In AC mode, the UPS system automatically tracks AC phase and ensures that the
output wave form of the inverter is the same with AC voltage wave form. In this way, it
reduces the peak pulse and surge voltage to minimizes the interference and damage
to the equipment.

7|ENGLISH
4.5 The Function of the Self-set Frequency
When the UPS is turned on for the first time, the acquiescence frequency is 50/60Hz;
when it is connected to AC, the frequency is automatically set to 50Hz or 60Hz in
accordance with AC.
5.0 LCD Display
The UPS is equipped with an LCD display. The display shows the following
information:
•Input voltage
•Output voltage
•The battery status/level
•Power usage in percent
•UPS status indication
•Low Battery indication
•Over load indication
6.0 Installing the UPS
