The UPS contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside
the UPS.
The UPS contains its own energy source (batteries). 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 (90%
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 millamperes.
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.
Batteries can present a risk of electrical shock or burn from high short-circuit current.
Observe proper precautions. Servicing should be performed by qualified service personnel
knowledgeable of batteries and required precautions. 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.
