Items marked with an (*) are specified at rated conditions under balanced linear loads.
(**) Battery backup time may vary depending on the operating conditions and ambient temperature at the installation site, and an initial
charge time of 24 hrs is necessary to obtain proper battery performance level before the unit is placed in operation.
(***) At 6600-ft (2000 m) above sea level, output capacity should be derated by 3% (Consult Factory for higher elevations).
(****) Prolonged operation at this level requires some derating of the output capacity.
