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).

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.
