3.5 Installation notes

 

 

Note:  Consider  for  the  convenience  of  operation  and  maintenance,  the  space  in 

front and back of the cabinet should be left at least 100cm and 80cm respectively when 
installing the cabinet . 

Please  place  the  UPS  in  a  clean,  stable  environment,  avoid  the  vibration,  dust,  humidity, 

flammable  gas  and  liquid,  corrosive.  To  avoid  from  high  room  temperature,  a  system  of  room 
extractor fans is recommended to be installed. Optional air filters are available if the UPS operates 
in a dusty environment. 

 

The  environment  temperature  around  UPS  should  keep  in  a  range  of  0

℃~

40

.  If  the 

environment temperature exceeds 40

, the rated load capacity should be reduced by 12

% 

per 

5

. The max temperature can't be higher than 50

If the UPS is dismantled  under low temperature, it might be in a condensing condition.The 

UPS  can't  be  installed  unless  the  internal  and  external  of the  equipment  is  fully  dry.  Otherwise, 
there will be in danger of electric shock. 

Batteries should be mounted in an environment where the temperature is within the required 

specs. Temperature is a major factor in determining battery life and capacity. In a normal 
installation, the battery temperature is maintained between 15°C and 25°C. Keep batteries away 
from heat sources or main air ventilation area, etc. 

 

 

WARNING!

 

Typical  battery  performance  data  are  quoted  for  an  operating 
temperature between 20°C and 25°C. Operating it above this range will 
reduce the battery life while operation below this range will reduce the 
battery capacity.

 

 

 

Should  the  equipment  not  be  installed  immediately  it  must  be  stored  in  a  room  so  as  to 

protect it against excessive humidity and or heat sources

 

 

 

 

CAUTION!

 

 

An  unused  battery  must  be  recharged  every  6months  Temporarily 
connecting the UPS to a suitable AC supply mains and activating it for 
the time required for recharging the batteries.

 

 

The  highest  altitude  that  UPS  may  work  normally  with  full  load  is  1500  meters. The  load 

capacity should be reduced when this UPS is installed in place whose altitude is higher than 1500 
meters, shown as the following table: 

Load  coefficient  equals  max  load  in  high  altitude  place  divided  by  nominal  power  of  the 

UPS

The  UPS  cooling  is  depending  on  fan,  so  it  should  be  kept  in  good  air  ventilation  area. 

There are many ventilation holes on the front and rear, so they should not be blocked by any exotic 
obstacles.
