3 .4 UPS installation

Before installing the UPS, please read below to
select proper location to install UPS.
1. UPS should be placed on the flat and clean
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, where it is away from window
and door. Maintain minimum clearance of
100mm in the bottom of the UPS to avoid dust
and high temperature.

2. Maintain an ambient temperature range of 0ºC
to 45ºC for UPS optimal operation. For every
5ºC above 45 C, the UPS will derate 12% of
o
nominal capacity at full load. The highest
working temperature requirement for UPS
operation is 50 C.

3. It's required to maintain maximum altitude of
1000m to keep UPS normal operation at full
load UPS. 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. Place UPS:
It's equipped with 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 and two sides of
the UPS for heat dissipation and
easy-maintenance.

External battery pack
When connecting external battery packs,
please be sure to connect polarity
correctly. Connect positive pole of battery
pack to positive pole of external battery
connector in UPS and negative pole of
battery pack to negative pole of external
battery connector in UPS. Polarity
misconnection will cause UPS internal
fault. It's recommended to add one
breaker between positive pole of battery
pack and positive pole of external battery

connector in UPS to prevent damage to
battery packs from internal fault.
The required specification of breaker:
voltage ≥ 1.25 x battery voltage/set;
current ≤ 50A.
Please choose battery size and connected
numbers according to backup time
requirement and UPS specifications.
To extend battery lifecycle, it's
recommended to use them in the
temperature range of 15
