anesthesia ventilators, infusion pumps, and any other device designated as “critical” by the
U.S.F.D.A.
Hospital grade wiring devices and leakage current may be ordered as options on many APC UPS
systems, APC does not claim that units with this modification are certified or listed as Hospital
Grade by APC or any other organization. Therefore these units do not meet the requirements for use
in direct patient care.
ELECTRICAL SAFETY
n To reduce the risk of fire, connect only to a circuit provided with a 30 Amp maximum branch
circuit overcurrent protection in accordance with the National Electrical Code ANSI/NFPA or
country specific electrical code.
n Do not work alone under hazardous conditions.
n Check that the power cord(s), plug(s), and sockets are in good condition.
n To reduce the risk of electric shock when grounding, disconnect the equipment from the AC
power outlet before installing or connecting to other equipment. Reconnect the power cord only
after all connections are made.
n Use one hand, whenever possible, to connect or disconnect signal cables to avoid a possible shock
from touching two surfaces with different electrical grounds.
n Connect the equipment to a three wire AC outlet (two poles plus ground). The receptacle must be
connected to appropriate branch circuit/mains protection (fuse or circuit breaker). Connection to
any other type of receptacle may result in a shock hazard.
n In order to maintain compliance with the EMC directive, output cords attached to the UPS should
not exceed 10 meters in length.
DEENERGIZING SAFETY
n If the equipment has an internal energy source (battery), the output may be energized when the
unit is not connected to an AC power outlet.
n To deenergize pluggable equipment, press the OFF button for more than one second to
switch the equipment off. Disconnect the equipment from the AC power outlet. Unplug the bat-
tery connector. Push the button labeled to deenergize the capacitors.
n Pluggable equipment includes a protective earth conductor that carries t he leakage current from
the load devices (computer equipment). Total leakage current must not exceed 3.5 mA.
n To deenergize permanently wired equipment: set the power switch to standby .
n Set the AC circuit breaker to standby , and then disconnect the batteries (including any expan-
sion units). Finally, disconnect the AC power from the building power supply.
n Use of this equipment in life support applications where failure of this equipment can reasonably
be expected to cause the failure of the life support equipment or to significantly affect its safety
or effectiveness is not recommended.
