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.
This 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.
S
This UPS contains its own energy source (batteries). The output receptacles may carry live voltage
even when the UPS is not connected to an AC supply.
S
The output receptacles may have live voltages even in Standby or remote emergency power-off
(REPO) mode. For example, with line-to-line input wiring (208V line-to-line, single-phase), the voltage
at the output receptacles is 110–120V (measured from neutral-to-ground).
S
Do not remove or unplug the input cord when the UPS is turned on. This removes the safety ground
from the UPS and the equipment connected to the UPS.
S
To reduce the risk of fire or electric shock, install this 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).
S
For all UPS models, overcurrent protection for the input and output AC circuit(s) is to be provided by
others. To reduce the risk of fire, connect only to a circuit provided with branch circuit overcurrent
protection for 60 amperes (10 kVA models) or 50 amperes (7.5 kVA models) rating in accordance with
the NEC, ANSI/NFPA 70.
S
For all UPS models, suitably rated disconnect switches for the output AC circuit(s) are to be provided
by others. To reduce the risk of fire, connect only to a circuit provided with branch circuit overcurrent
protection for 50 amperes rating in accordance with the NEC, ANSI/NFPA 70.
S
High leakage current. Earth connection is essential before connecting supply.
S
Risk of electric shock. Battery circuit is not isolated from AC input. Hazardous voltages might exist
between battery terminals and ground. Test before touching.
S
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.
S
Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
S
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
