In this case, it’s important that you make sure you never arm your multirotor when the main ESC power
connector is disconnected from the Current Sensor/PSU. Or, you can address this issue in some other ways:
a) remove/disconnect the red wire from the “Ail”
connector, so that power will not pass from
your receiver to the ESCs when using the 5V
tap to power your receiver.
b) Or, remove/disconnect the power servo wire
from each ESC. This may be required anyway,
as some non-optoisolated ESCs could be
damaged if the red wires are connected
together.
c) Or, be sure to never connect your main pack to the current sensor without having the ESC main power
connector also plugged into the current sensor.
If one of these steps is not followed, your ESCs will receive power even when the ESC main power
connector is not plugged into the current sensor. This can cause at least two potential problems if you
arm the multirotor in this condition:
The propellers can spin even though the main pack is not connected to the ESCs!
With some ESCs, a brownout can occur in this condition that has been known to cause these ESCs to
reprogram their endpoints. This can lead to unpredictable results such as propellers spinning at
different speeds after arming, possibly creating an unsafe condition!
