2. Introduction
Thank you for selecting an Eaton product to protect your equipment.
The Eaton 3SMini range has been designed with the utmost care. We recommend
that you take the time to read this advanced user guide and documentations provided
to take full advantage of the many features of your UPS (Uninterruptible Power
System).
Before installing your Eaton 3SMini, please read the information and safety
instructions provided. Follow the instructions in the quick start guide and if necessary,
refer to this advance user guide.
To discover the entire range of Eaton products, we invite you to visit our web site at

4.2. Safety
For product installation or additional information refer to the Quick Start and Advanced
User Guide. For customer support please contact your local after sales services.
DANGER: Dangerous voltage levels are present within the UPS. Do not
attempt to open the unit.
CAUTION: Do not dispose of batteries in a fire. When exposed to flame,
batteries may explode. Do not open or mutilate the battery or batteries. Released
electrolyte is harmful to the skin and eyes and may be extremely toxic.
Installation
Check that the indications on the rating plate correspond to your AC-power
system and to the actual electrical consumption of all the equipment to be connected
to the UPS. For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near
the equipment and shall be easily accessible. Ensure that AC main outlet is properly
earthed.
The UPS and their batteries must be kept in a ventilated place. Never expose the UPS
to direct sunlight or source of heat. This equipment should only be used in a dry indoor
environment. The admissible storage conditions are -20°C to +45°C (around 3 Months)
and +25°C max (1 year+). 0% to 95% of humidity non-condensing.
Do not place the UPS on any heat source or electronic equipment.
Use and Maintenance
There are no user serviceable parts inside the UPS.
Environmental Notice
Eaton has implemented an environmental-protection policy. Our products are
developed according to an eco-design approach (eaton.com/productstewardship).
Battery: The product contains batteries that must be processed according to
applicable local regulations concerning batteries.
The product includes Li-ion batteries, follow end-of-life instruction in view of
correct waste disposal

4.3. Power supply cord / socket
Connect the UPS to the AC power source through a wall-protected outlet equipped with an
earth connector, using the attached cord for a UPS with FR/DIN (CEE7/7) or British (BS1363)
sockets.
Figure 1 FR/DIN example
Initial power-on requires that the UPS is plugged to main first.

4.5. Voltage setup
Before entering voltage setup, ensure that the protected equipment is
disconnected from the UPS:
Figure 4 Disconnect the equipment
Then enter voltage setup mode and select the appropriate output DC voltage
corresponding to equipment nominal input voltage (9V, 12, 15V or 19V):
•Press the ON/OFF button (5) for eight seconds
Important: The LED and UPS will briefly shut down (OFF to 0V) during the
process and it will turn off any connected equipment, just keep pressing the
button until eight seconds have passed.When LED start flashing (slow), release
the button.

•You can then cycle through the different LED position which indicate the
voltage output by pressing the ON/OFF button (quick press).
Note that the voltage is not active until the selection is confirmed.
Figure 5 Cycle through the voltage levels
•Once the voltage is selected, then simply press eight seconds to confirm the
choice. The LED will stop blinking and steady itself.
The DC output is now delivering the new voltage.

8. Equipment care
For full battery life, keep the equipment at an ambient temperature of 25 °C (77 °F).
Battery service life is reduced as follows;
0<T≤10℃，440mAh
10<T≤45℃，2200mAh
45<T≤55℃，1100mAh
It is recommended to fully charge the battery after initial setup and if possible,
to perform two or three cycles of charge/discharge.
If the UPS requires any type of transportation, verify that the UPS is turned off.
