5.4 Overload Condition
The working principle of the UPS when overloading is illustrated as follows
：
(1) Generally, modern electronics & IT equipment generate an inrush current
when switching on. The amount of inrush current varies from equipment to
equipment, some can be as high as 6 times its rated capacity while others
produce negligible inrush. To prevent severe damage to the Inverter, caused
by inrush produced by loads, the UPS is equipped with an electronic overload
protection feature. If the UPS load is >105~120% of its capacity, it will switch
to bypass mode in 30 seconds to protect the Inverter. If the overload condition
is eliminated by reducing the load to <105%, the UPS will switch back to
Inverter mode automatically. If the UPS is over 150% loading, it inverter will
shutdown immediately.
