WITH AIR or WITH OXYGENOR NITROUS
OXIDE.
Not designed, intended or authorized for use in
systems intended to support or sustain life.
For more details on life critical applications please
refer to full disclaimer in AppendixA: Warranty on
page 18 at the end of this manual.
WARNING: This equipment services power from
more than one source. The output receptacles may
have voltages present even when the unit is
unplugged.
UPSs present a different safety issue than most
electrical equipment because unplugging the UPS
puts it into backup mode. Unplugging the UPS does
not remove the electrical charge. To ensure that the
UPS is off, turn the power switch “OFF” before
unplugging the UPS from the wall outlet.
CAUTION: This unit is intended to be used in a
system that has a grounded neutral conductor.
CAUTION: Operating this equipment without
proper grounding may present a risk of electrical
shock.
Do not useAC adaptors with only two conductors to
connect the input line cord to the wall socket as this
will not connect the earth ground to the equipment.
WARNING: Dangerous voltages are present within
this unit! There are no user-serviceable parts inside.
Any repairs or modifications by the user may result
in out-of-warranty repair charges, unsafe electrical
conditions, or violation of electrical code.
Do not remove the cover. All repairs should be done
by qualified service personnel. Voltages inside the
UPS may be lethal. Internal components are
