The surface of the gateway may become hot during normal operation, affecting the
surrounding environment.
All installation operations must comply with local and national electrical codes.
Do not operate the equipment during lightning.
The gateway runs continuously during the life cycle, and it is necessary to ensure that it is
grounded well and stably.
Install the grounding first, and remove grounding wire last at the time of dismantling.
It is forbidden to operate the gateway with power.
The power supply device of the gateway must include overcurrent protection function.
2.2 Unpacking inspection

Figure 5 Antenna installation completion display
Note: For the RF part of antenna connected to the inside of the gateway, its installation needs to
pay attention to the external lightning protection. An antenna feed arrester should be installed between
the LoRa antenna and the gateway, and the antenna must be installed within the protection area of the
lightning rod.
