1.Entry-Level UPS user guide
Users can connect the AC charging cable of the EF DELTA to the power grid and connect an appliance to the EF DELTA. Turn on the AC switch to
automatically enter the entry-level UPS mode. When the external power is cut off, power will be supplied from the battery immediately to protect your
device.
2 . Series mode user guide
(recommended for power users; all machines must be fully charged)
Users can connect multiple fully-charged EF DELTAs (up to 3) in series using the AC charging line to obtain multiple times the continuous
power and meet the needs for high-power appliances that must be operated at full load for up to 1.8 hours. In this mode, do not connect the
multiple EF DELTAs to the power grid using the AC charging cable or the overcurrent protection (<20A) may be triggered. Connect the EF
DELTAs to a home power grid and charge them separately. It is recommended not to charge more than two machines simultaneously.
Otherwise, the excessive load may trip the home power grid. To use this function, we need to define the division of labor between the
machines. You can set any of the machines as the master and the others as Slave 1 and last slave unit. Connect one end of the AC cable to the
AC output port of the master unit and the other end to the input port of Slave 1. Then, connect one end of the AC cable to the AC output port
of Slave 1 and the other end to the input port of last slave unit . After connecting the machines, turn all the AC switches of the machines on to
activate multi-machine series mode. Finally, connect all the appliances to the AC sockets of the last slave unit and you can operate the
appliances normally and enjoy the benefits of extended battery life.
