Installation and Operation 

 

Installing  the  UPS  is  as  easy  as  following  the  steps  shown.    Be 
aware  of  the  Power  Switch  must  be  kept  in  the  “ON”  position, 
otherwise, the UPS will be disabled and your equipment will not be 
protected during a power failure. 

 

1.

 

Inspection 

Remove  the  UPS  from  its  packaging  and  inspect  it  for  damage  that 
may  have  occurred  during  shipping.  If  any  damage  is  discovered, 
repack the unit and return it to the place of purchase. 

 

2. 

Placement 

Install  the  UPS  unit  in  any  protected  environment  that  provides 
adequate  airflow  around  the  unit,  and  is  free  from  excessive  dust, 
corrosive  fumes  and  conductive  contaminants.  Do  not  operate  your 
UPS in an environment where the ambient temperature or humidity is 
high. On the other hand, place the UPS unit away from monitor at least 
20cm to avoid interference. 
 

3. 

Charging 

 

This  unit  is  shipped  from  the  factory  with  its  internal  battery  fully 
charged.  however,  some  energy  may  be  lost  during  shipping  so  the 
battery  should  be  recharged  before  using  it.  Plug  the  unit  into  an 
appropriate power supply and allow the UPS to charge fully by leaving 
it plugged in for 8 hours.
