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
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 this UPS must not
have an earth leakage current greater than 3.5 milliamperes.
