Environmental Conditions

1. The main unit should be able to operate normally under the following environmental conditions;
a) Ambient temperature: 0℃ to +40℃;
b) Ambient relative humidity: not more than 95% (+25℃);
c) Atmospheric pressure: 80kPa to 106kPa;
d) No significant vibration or shock;
e) In hazardous locations with methane and coal dust explosive gas mixtures;
f) No steam or corrosive gases that damage metal and insulating materials;
2. The harshest storage and transportation conditions the main unit can withstand:
a) Temperature: -40℃ to +60℃;
b) Humidity: 95% (+40℃);
c) Vibration: 50m/s²;
d) Shock: 500m/s².

System Grounding   
As part of the entire acquisition system, effective grounding loop connection of the main unit is one of the important conditions to ensure the system operates normally. Improper connections can cause current flow in the loop due to potential differences between grounding points, introducing noise into the system. Installation should be guided by professionals.
In industrial sites where uncertain interference signal sources exist, the cable shielding layer should be reliably connected to earth (PGND) with contact resistance below a certain limit, and must not be laid parallel to power cables.

Explosion-proof   
For explosion-proof applications, the product must have an "Explosion-proof Certificate" issued by an inspection unit and a "Safety Mark Certificate" for mining products issued by a national authorized agency. Only products with the mining product "Safety Mark Certificate" are allowed for underground use.

Product Maintenance   
The main unit is a precision acquisition product; the power supply voltage used must not exceed the voltage type and upper limit specified in the product technical documentation.
The main unit must be properly stored; when not in use, it should be placed in a dry location, and during use, it should be protected from drops or impacts from external objects.
To ensure its electrical insulation performance, users should prevent contamination of the main unit housing. After long-term storage, it should be visually inspected, and if contaminated, cleaned with industrial alcohol.
Under no circumstances should users disassemble the product themselves, as this will cause the main unit to be scrapped.
The main unit must not be used beyond the conditions specified in this manual.

Transportation and Storage   
The packaged main unit is suitable for road, rail, water, and air transportation, and must be protected from rain and impact during transport.
After packaging, the equipment should be stored in a warehouse with an ambient temperature of -20℃ to +40℃, relative humidity below 95% (+25℃), good ventilation, and free of corrosive gases.
