Safety guidelines

Before installing or operating the Efento Gateway, please read the safety information carefully. The device contains components and features that, if used incorrectly, may pose certain risks. These include:

• Li-Po backup battery risks (LTE Gateway only), such as potential damage or reduced performance if the device is exposed to extreme conditions or mishandled.

• Risks associated with connecting the device to a power supply, including the use of incompatible or low-quality power adapters that may cause overheating, electrical faults, or decreased device reliability.

• Risks related to operating the gateway without the required antennas, which may lead to device malfunction or permanent damage to the communication modules.

Li-Po backup battery risks (LTE Gateway only)

The Efento LTE Gateway is equipped with a Li-Po (lithium-polymer) backup battery that ensures continued operation during power outages.

While Li-Po batteries are safe when handled correctly, improper use may lead to reduced performance, damage, or safety hazards.

To minimize risk, follow these guidelines:

• Avoid exposure to extreme temperatures. Do not operate or store the device in very high or very low temperatures. Excessive heat may cause battery swelling or degradation, while cold conditions can reduce battery capacity and performance.

• Do not puncture, crush, or apply pressure to the device. Physical damage may compromise the battery’s integrity and lead to leakage, overheating, or failure.

• Keep the device away from moisture. Water or high humidity can damage the battery and increase the risk of malfunction.

• Do not attempt to open or replace the battery. The battery is built into the device and must only be serviced or replaced by authorized personnel. Tampering may result in safety risks and void the warranty.

• Watch for signs of battery issues. If you notice unusual heat, odor, discoloration, or swelling of the device, disconnect it from the power supply immediately and stop using it.

• Store the device properly when not in use. For long-term storage, keep the gateway in a cool, dry place and charge it periodically to maintain battery health.

Power supply risks

The Efento Gateway must be connected to a suitable power source to operate safely and reliably.

Incorrect power supply usage may damage the device or create electrical hazards.

To avoid these risks, follow the guidelines below:

• Use only a certified 5V, 1A USB power adapter. Using power supplies with incorrect voltage or current ratings may cause overheating, unstable operation, or permanent damage to the gateway.

• Avoid low-quality or unapproved adapters. Poor-quality chargers may generate electrical noise, voltage spikes, or insufficient power, which can lead to data transmission issues or device malfunction.

• Inspect the power cable and adapter regularly. Do not use damaged, frayed, or loose cables. Faulty connectors may increase the risk of short circuits or fire.

• Ensure the power adapter is used in a dry environment. Water or moisture near power connectors may cause electric shock or damage to the gateway.

• Prevent overheating. Do not place the power adapter under objects or in confined spaces. Ensure sufficient airflow around both the adapter and the gateway.

• Do not connect or disconnect the power supply with wet hands. This may lead to electric shock or damage to the device.

• Use surge protection where possible. In areas with unstable power grids, using surge protectors reduces the risk of voltage spikes damaging the gateway.

Antenna related risks

The Efento Gateway requires properly connected antennas to ensure safe and reliable operation of its wireless communication modules.

Using the device without antennas, or with antennas improperly installed, may lead to performance issues or permanent hardware damage.

To avoid these risks, follow the guidelines below:

• Always install the antennas before powering on the device. Operating the gateway without antennas may cause the LTE or Bluetooth modules to transmit at unsafe power levels, potentially damaging the internal radio components.

• Do not use incompatible antennas. Only use the antennas supplied with the device or approved replacements. Incorrect antenna types may lead to reduced performance or hardware stress.

• Avoid bending, crushing, or modifying antennas. Damaged antennas can impair wireless performance and increase the risk of overheating in the communication modules.

Other risks

Several other factors may affect the safe and reliable operation of the Efento Gateway. To prevent device damage or operational issues, observe the following guidelines:

• Do not expose the device to liquids or high humidity. The gateway is not waterproof. Contact with water may cause internal damage, corrosion, or electrical failure.

• Protect the device from mechanical shock. Dropping, striking, or applying excessive force to the gateway may damage internal components, connectors, or the enclosure.

• Avoid installing the device in unstable or vibrating locations. Continuous movement or vibration can loosen connectors, damage components, or interrupt communication.

• Keep the device away from strong electromagnetic fields. Placing the gateway near high-power electrical equipment, industrial machinery, or magnetic sources may interfere with wireless communication or disrupt device operation.

• Do not block ventilation openings. Ensure sufficient airflow around the device to prevent overheating, which may shorten component lifespan or cause performance issues.

• Use the device only as intended. Modifying the hardware, using non-approved accessories, or attempting to repair the gateway without authorization may result in malfunction, safety risks, and voided warranty.

• Follow local regulations and installation guidelines. Improper mounting or use in restricted areas (e.g., near medical or aviation equipment) may cause interference or violate regulatory requirements.
