This chapter introduces the contents covering proper handling of the Radar, hazard prevention,
and prevention of property damage. Read these contents carefully before using the Radar,
comply with them when using, and keep the manual well for future reference.
Pay attention to personnel safety when installing the Radar at intersections or certain road
sections.
Non-professionals are forbidden to disassemble and install the Radar.
Before powering on the Radar, check all the power connections to prevent short circuit.
Properly ground the Radar.
Securely install the Radar to reduce the impact of vibration on the Radar.
The cables must meet the requirements of shielding, insulation, and moisture resistance.
Power Source Requirements
Use high-quality DC power supply that meets the voltage requirements to avoid crosstalk
from other devices.
Strictly comply with the local electric safety standards.
Make sure that the power supply is correct before operating the Radar.
Use power supply that meets SELV (safety extra low voltage) requirements, and supply
power with rated voltage that conforms to Limited Power Source in IEC60950-1. For
specific power supply requirements, please refer to device labels.
Install easy-to-use device for power off before installing cables, which is for emergent
power off when necessary.
Prevent the line cord from being trampled or pressed, especially the plug, power socket
and the junction.
Application Environment Requirements
Make sure that there are no obstructions in the front of the Radar.
Do not hot swap the serial port.
Do not impact the Radar. Prevent the Radar from falling down.
Do not aim the Radar at strong light (such as lamplight, sunlight) for focusing.
Transport, use and store the Radar under the allowed humidity and temperature
conditions.
Prevent any liquid from flowing into the Radar.
Do not block the ventilation near the Radar.
Do not press, vibrate or soak the Radar during transportation, storage and installation.
Pack the Radar with packaging materials provided by its manufacturer or materials with the
