Preparation Before Installation

 Safety Instructions
Before installation, read the safety advice in this manual carefully to avoid doing harm to people and equipment.

Note that the following safety advice cannot cover all possible dangerous situations.

Installation

1.  Do not install the equipment in environments with high temperature, heavy dust, harmful gases, flammables, explosives, electromagnetic interference (for example, around large radar stations, transmitting stations, and substations). unstable voltages, great vibration, and strong noise.
2. Do not install the equipment in places where water is likely to accumulate, seep, drip, and condense.

Disassembly

1. After installation, do not frequently disassemble the equipment; otherwise, the equipment can be damaged.
2. Before disassembly, turn off all power supplies and disconnect the cable from the battery to avoid equipment damage.

Electrical Operations

1. Electrical operations must be performed by qualified personnel in accordance with local laws and regulations.
2. Carefully check the working area for potential hazards, such as wet ground.
3.  Before installation, learn about the position of the emergency stop button. Use this button to cut off the power supply in case of accidents.
4. Before cutting off the power supply, ensure that the equipment is turned off.
5. Do not put the equipment in a humid place. Prevent liquids from entering the equipment.
6. Keep it away from high power wireless equipment such as wireless transmitters, radar transmitters, high frequency and current devices, and microwave ovens.
7. Direct or indirect contact with high voltage or utility power may cause death.

Requirements for Installation Site
To ensure the normal operation of the equipment and prolong its service life, the installation site must meet the following requirements.

Position

1. Ensure that the installation position is firm enough to support the control terminal and accessories.
2.  Ensure that there is enough space to install the control terminal at the installation position, with some space set aside in every direction for heat dissipation.

Temperature and Humidity

1. The temperature and humidity of the working environment should be kept within a reasonable range to ensure the normal operation and service life of the equipment.
2. The equipment will be damaged if it works under improper environmental temperature and humidity.
3. When the relative humidity is too high, insulating materials may not perform well, causing leakage currents. Mechanical property changes, rusting, and corrosion may also occur.
4. When the relative humidity is too low, insulating materials will dry and contract, and static electricity may occur and damage the electric circuits of the equipment.

Air
Ensure that the contents of salt, acid, and sulfide in the air are within a reasonable range. Some hazardous substances will accelerate the rusting and corrosion of metals and the aging of parts. Keep the working environment free of harmful gases (for example, sulfur dioxide, hydrogen sulfide, nitrogen dioxide, and chlorine).

Power Supply

1. Voltage input: The input voltage of Agricultural Guidance System should be in the range of 12 V to 24 V.
2. Connect the power cable to the positive and negative electrodes correctly and avoid direct contact of the cable with hot objects.
