4.1 Installation notice
1. Install the UPS in a clean and stable environment that is free of vibration, dust, high humidity, flammable
gas, flammable liquid or caustic substance.
2. The ambient temperature for the normal running UPS is required to be at 0
℃
- 40
℃
. If the UPS is operat-
ing in a more than 40
℃
environment, the maximum load capacity is required to be in accordance with the rat-
ing by 12% capacity decrease for every 5
℃
temperature rise. The maximum ambient temperature is required
to be no more than 50
℃
.
3. It is recommended that the battery pack be used at the temperature of 15
℃
-25
℃
.
4. Altitude for normal UPS function should not exceed 1000m. Should UPS be intended for application above
1000m, progressive decrease of rated output should be applied as listed in the following:

5. 3A3 Pro UPS utilizes fans for forced cooling, so considering ventilation for installation site is a must. Do
not block the panels since there are ventilation grids in both the front and rear panels of the UPS.
6. 3A3 Pro UPS adopts the positive-negative battery supply configuration. One battery pack consists of 32-
40 batteries in series, which is divided into two parts by a neutral wire connecting to the middle of the pack.
Therefore there are altogether three wires connected with the UPS terminal blocks including the positive and
negative wires of the battery pack. The batteries between the positive terminal of the battery pack and the
neutral wire are positive battery; while the batteries between the negative terminal and the neutral wire are
negative battery (refer to the connection diagram for detailed information). You can choose the battery
capacity and battery pack quantity according to your need. UPS capacity is varied with different battery con-
figuration. The de-rating factor is shown in below table:

7. Wire Connection: the 3A3 Pro UPS is a three-phase input and three-phase output UPS and the input wire
must be connected to the three-phase live wire and neutral wire. The output can be connected in different
ways (
△
, Y or some other ways) according to the loads. Refer to the connection diagram for detailed infor-
mation.
8. Wiring standard: the 3A3 Pro UPS adopts modular design and you may choose the quantity of the modules
according to the load. It is recommended that the wiring be connected according to the maximum load for the
safe use of the unit and the easy load expansion. The user can also perform the wiring according to the capac-
ity of the modules. Refer to the table of wiring configuration in this manual.
