• 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.

• This UPS should not be supplied from electrical power sys­tems of the “IT” (Impedance á Terre) type (IEC 364 - Elec­trical Installation of Buildings).
