Requirement
Machine Hall Space
When installing the machine frame array into a machine hall, the distance
between 2 rows of machine frames should be 1.2 ~ 1.5 m and the distance
between a machine frame and a wall should be no less than 0.8 m.
Machine Hall Floor
Electric Isolation, Dust Free
Volume resistivity of ground anti-static material: 1×10
7
~ 1×10
10
Ω
Grounding current limiting resistance: 1M (Floor bearing should be greater
than 450 kg/
㎡
)
Environment
Temperature
5 ~ 40
°C
(sustainable), 0 ~ 45°C(temporary)
Installing air-conditioning is recommended
Relative Temperature
20% ~ 80% (sustainable), 10% ~ 90% (temporary)
Pressure
86 ~ 105 kPa
Door & Window
Install rubber strips to seal door gaps and dual-level window glasses.
Wall
Can be covered with wallpaper or non-bright paint.
Fire Protection
Fire alarm system and extinguisher
Power
Device power, air conditioning power, and lighting power should all be
independent of each other. Device power requires AC power 220V 50 Hz.
Please check carefully before running.
Good grounding designs are the basis of reliability and stability for these devices. Good
grounding is also the best guarantee against lightning arresting and interference rejection.
All machine frames should be connected by protected copper strips
Coaxial cable outer conductors and isolation layers should maintain proper electrical
conduction with the metal housing of the device.
The grounding conductor should be copper in order to reduce high frequency impedance.
The grounding wire should be as thick and short as possible and avoid circling.
Users should make sure both ends of the grounding wire are good conductors and rust-
resistant.
Users should not use any other device as part of the grounding electric circuit.
The area of conduction between the grounding wire and device’s frame should be no less than
25 mm
2
.
Connect the device’s grounding rod to the frame’s grounding pole with copper wire.
