GENERAL INSTALLATION 

 
1. Unpack the unit and check the contents.  There should be one UPS with 

power cord (8) and one User’s Manual. 

 

2. Check the items for damage.  If any appear faulty or damaged, contact your 

dealer immediately.  Store the packaging in a safe place for possible future 
shipment of UPS. 

 

3. Place the UPS on a sturdy, dry surface in a well ventilated area away from 

direct  heat sources.  Leave at least 4 inch (100 cm) clearance all around the 
UPS to provide adequate ventilation. 

 

4. Plug in the UPS and turn the UPS control switch (1) to ON. 

 

5. Plugging in the UPS charges the batteries.  Charge the UPS batteries for 12 

hours before connecting the load equipment. 

 

6. After charging the UPS, shut down your computer and unplug it.  Plug the 

computer equipment into the UPS AC outputs (7). 

 

7. When all equipment is plugged in, the UPS is ready for normal operation.
