[1]  Reverse battery voltage is only allowed with external resistors to limit the input and status currents to a safe value. The connected load must limit the reverse current. The internal groud resistor limits the reverse battery groud current.
[2]  To limit input current during reverse battery and transient overvoltages.
[3]  To limit status current during reverse battery and transient overvoltages.
