b) main power supply and separate by-pass
a) Single power line (F input line protection)
The UPS input must have a max. current
protection device for the section of line coming
from the distribution panel. The fuse
represented with the letter F.
b) main power supply and by-pass separate
(Fmains and G by-pass input line protection)
When there are two separate power lines, the
