5.2 Wiring Notes

Strictly distinguish AC and DC power interfaces. Never connect 220V AC to DC circuits to avoid equipment burnout.

RS485 serial ports have positive and negative polarities, reverse connection will cause communication failure.

Do not short-circuit dimming interfaces, confirm dimming mode matching between gateway and lamp drivers before wiring.

Conduct waterproof and insulation treatment for outdoor wiring, separate strong and weak cables to avoid signal interference.

Install antennas away from high-voltage circuits to ensure stable 4G & WiFi wireless signal transmission.

6 Installation & Operation Requirements

Install the device in the weak current cabin inside street lamp poles, in dry, well-ventilated positions without water accumulation and strong electromagnetic interference.

Fix the device firmly to prevent cable falling off and interface loosening caused by outdoor vibration.

Comply with national low-voltage electrical safety specifications, separate strong and weak wiring and complete reliable grounding protection.

Do not disassemble or open the metal gateway shell privately, to prevent internal components from dampness, dust ingress and damage.

Do not operate the device beyond rated temperature and humidity range, avoid damage caused by condensation, extreme high temperature exposure or low temperature freezing.

All parameter debugging and configuration must be operated by professional electrical & IoT technicians, non-professionals are prohibited from modifying gateway settings randomly.

7 Warranty & Disclaimer Clauses

Our company will not bear warranty and compensation liability for equipment failure and abnormal operation caused by non-standard operation, private disassembly & modification by non-professionals, mismatched load connection and illegal wiring.

The whole-machine original warranty will become invalid immediately once the metal device shell is opened privately.
