Installation Guide
4.1.
Installation Preparation
•
Check possible lose or damage of the device during transportation and read the complete user
manual.
•
Prepare a suitable environment for installation.
•
Install the device.
•
Connect the Signal cables.
4.2.
Environment Requirement
•
It is recommended to take into account the following point related with the installation
environment:
•
When installing multi-‐row of racks, please make the distance 1.2~1.5M between front door and
back door, and the distance 0.8M between rack and wall.
•
The floor of the room where is installed the device should be non-‐conducting, dust free.
Anti-‐static material volume resistivity: 1x107 ÷ 1x1010 Ω, ground current-‐limiting resistance:
1MΩ, floor bearing weight: > 450Kg/m2.
•
Working temperature: for long term operation: 5 ÷ 40º C, for short term operation: 0 ÷ 45º.
•
Relative humidity: for long term operation: 20% ÷80 %, for short term operation: 10% ÷ 90%.
4.3.
Grounding Requirement
Good ground wire design is the base of the whole system, and is essential to lightning protection and
anti-‐interference. The system must follow above principles:
•
Keep good electrical contact between both ends of outer conductor and shielding layer and the
appearance of metal case of the connected device.
•
Make sure that connections of both ends of the ground wire are with good electrical contact
and prepare for corrosion prevention treatment.
•
Do not use other device for ground wire electrical connection.
•
The sectional area of ground wire from rack connecting to anti-‐thunder unit must be greater
than or equal to 25mm2
