IMPORTANT SAFETY INSTRUCTIONS
(
Save these instructions
)
Units in this manual are intended for installation in a temperature-controlled, indoor area
free of conductive contaminants.
Read all instructions carefully before operating the UPS. All operating instructions should
be followed and all cautions must be adhered to.
CAUTION
-- UPS units use batteries for generation of AC voltages, so output receptacles
may be electrically hot even when the unit is not connected to commercial power.
Trained service personnel should perform all repairs, since an electrical shock hazard
exists.
CAUTION
-- Do not remove the cover, there are no user serviceable parts inside.
CAUTION
-- The 3-wire plug supplied with the unit provides earth ground for the UPS
unit chassis to prevent electrical shock. Plug the UPS unit into a 3-wire grounding type,
commercial receptacle with grounding conductor connected to earth ground at the
service equipment. Removal

adapter will defeat this safety feature and may result in a shock hazard. Additionally, if
