SAFETY PRECAUTIONS
• There are no user-serviceable parts inside this UPS except
the internal battery pack. Refer all UPS service to quali-
fied service personnel. Do not attempt to service this prod-
uct yourself.
• Output receptacles on the UPS are electrically live if the
UPS is switched on, even if the UPS is not plugged into a
Mains supply. The ON/OFF button on the UPS does not
electrically isolate the internal parts. Some components
are live even when Mains power is disconnected. To isolate
the UPS, switch off the UPS first, then unplug it from the
Mains.
• Opening or removing the cover may expose you to lethal
voltages within this unit even when it is apparently not
operating and the input wiring is disconnected from the
electrical source.
• Observe all CAUTION and WARNING statements in this
manual and on the unit. Failure to do so may result in
serious injury or death.
• Never work alone.
