Safety Warnings   

IMPORTANT SAFETY INSTRUCTIONS   

SAVE THESE INSTRUCTIONS 

This manual contains important instructions that you should follow during installation 
and maintenance of the UPS and batteries. Please read all instructions before operating 
the equipment and save this manual for future reference. 

 

DANGER 

THE  UPS  CONTAINS 

LETHAL  VOLTAGES.

  ONLY  AUTHORIZED  SERVICE 

PERSONNEL SHOULD PERFORM ALL  REPAIRS AND SERVICE

THERE ARE 

NO USER SERVICEABLE PARTS

 INSIDE THE UPS. 

 

WARNING 

 

The UPS output may carry live voltage even when the UPS is not connected to an 
AC supply. 

 

To reduce the risk of fire or electric shock, install the UPS in a temperature and 
humidity controlled, indoor environment, free of conductive contaminants. Ambient 
temperature must not exceed 40°C (104°F). Do not operate near water or excessive 
humidity (95% maximum).   

 

To  reduce  the risk  of  fire,  connect  only  to  a  circuit  provided  with  branch  circuit 
overcurrent  protection  in  accordance  with  the  National  Electrical  Code  (NEC), 
ANSI/NFPA 70. 

 

Output overcurrent protection and disconnect switch must be provided by others. 

 

To  comply  with  international  standards  and  wiring  regulations,  the  sum  of  the 
leakage current of the UPS and the total equipment connected to the output of the 
UPS must not have an earth leakage current greater than 3.5 milliamperes. 

 

If installing optional rackmount EBP(s), install the EBP(s) directly below the UPS 
so that all wiring between the cabinets is installed behind the front covers and is 
inaccessible to users. The maximum number of EBP(s) per UPS is four. 

 

If the UPS requires any type of transportation, verify that the UPS is unplugged and 
turned off and then disconnect the UPS internal battery connector. 

CAUTION

 

 

Batteries can present a risk of electrical shock or burn from high short-circuit current. 
Observe  proper  precautions.  Only  qualified  service  personnel  with  knowledge  of 
batteries and the required precautions should perform servicing. Keep unauthorized 
personnel away from batteries. 

 

Proper  disposal  of  batteries  is  required.  Refer  to  your  local  codes  for  disposal 
requirements. 

 

Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
