The maximum battery discharge current refers to the current when forty 12 V batteries in
standard configuration, that is, two hundred and forty 2 V battery cells (1.67 V/cell), stop
discharging.
When the mains input and bypass input share a power source, configure input power
cables as mains input power cables. In addition, cables listed in
the following conditions:
−
The cables are installed along the wall or on the floor (IEC-60364-5-52 C
standards).
−
The ambient temperature is 30°C.
−
The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%. The
recommended cable diameters in
meet the basic through-current
requirements. Users should evaluate the line voltage loss based on the actual cable
length. If the voltage loss exceeds the requirements, increase the cable diameter
properly.
−
The cables are single- or multi-core 90°C soft power cables with a copper
conductor.
