d. Fan indicator
The fan speed of the EF DELTA directly correlates with the load and the ambient temperature. The higher
the load or the ambient temperature, the higher the fan speed will be.
e. High Temperature Indicator
Indicates that EF DELTA's battery temperature is too high. All input and output functions will stop and the
fan will start working. Once the battery cools down, EF DELTA will automatically resume operating.
f. Low temperature indicator
Indicates that the battery temperature of EF DELTA is too low. All inputs and outputs will stop functioning
at this state. Please bring the EF DELTA to a warmer location and wait for the temperature to be within the
working range before restarting the EF DELTA.

i. Overload Warning
There are 2 levels of Overload Protection: Software Level: when the power pulled from the AC outlets
steadily exceeds the maximum AC power output, the overload indicator and AC indicator will flash
simultaneously for 15 seconds and the AC output will automatically and immediately be turned o . Other
ports will continue to work; Battery Level: when the power pulled from the AC outlets exceeds the
maximum AC power output, the overload indicator and AC indicator will flash simultaneously for 15
seconds and EF DELTA will automatically and immediately be turned o . Overload warning - There are two
types of overload protection. First level of protection: When any of the DC sockets exceeds the maximum
current limit or the output of any AC sockets exceeds the maximum AC power output (Overload of 1-10%
for 10min; overload of 11-20% for 1min; overload of 21-50% for 10s; overload of 51-100% for 100ms), and the
car power output exceeds the maximum current, the overload indicator and the indicator of the
corresponding socket will flash at the same time for 15s. Power supply to the socket will be cut o , while
other sockets will continue to work. Second level of protection: When the power output from any DC or AC
sockets or the car power outlet exceeds the maximum power output of the battery, the overload indicator
and the indicator of the corresponding socket will flash at the same time for 15s. The EF DELTA will shut
down automatically. Remove the device causing the overload and restart the EF DELTA to resume
operation.
