3.6 Grounding the Device
User MUST complete grounding wired with the device; otherwise, a sudden
lightning could cause fatal damage to the device. EMD (Lightning) DAMAGE IS
NOT COVERED UNDER WARRANTY.
3.7 Wiring the Fault Alarm Contact
The fault alarm contacts are in the middle of the terminal block connector as
the picture shows below. Inserting the wires, the LoRaWAN Gateway will detect
the fault status of the power failure or port failure, and then will form an open
circuit. The following illustration shows an application example for wiring the
fault alarm contacts
