Warning! This unit is intended to be used in a system that has a
grounded neutral conductor. Operating this equipment without proper
grounding may present a risk of electrical shock. Do not use AC
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! This equipment services power from more than one source.
The output receptacles may have voltage present even when the unit
is unplugged. 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.
