impedance (including grounding system) coupling and conductor (power line, signal line and output line, etc.)
conduction.
The machine room shall meet the following anti-interference requirements:

It is necessary to take effective measures to prevent the interference of the power system.

The working place of the equipment should not be Shared with the grounding device or lightning protection
grounding device of the power equipment, and should be as far apart as possible;

Far away from high-power radio transmitter, radar transmitter, high-frequency high-current equipment;

Electromagnetic shielding shall be adopted when necessary.
2.2.5 Lightning protection requirements
Although a great deal of consideration and necessary measures have been taken in lightning protection, the
equipment may still be damaged when the lightning intensity exceeds a certain range. In order to achieve better
lightning protection effect, it is recommended that users:

Ensure the protective ground of the chassis is in good contact with the ground with protective ground wire.

Make sure that the ground point of the ac socket is in good contact with the ground.

It can be considered that to add power arrester at the front of the power input,which can increase the power
lightening resistance.

In order to achieve better lightening protection effect, For the signal line connected to outdoor,such as ISDN
line,telephone line,the users can consider adding professional lightning protection device in the input end of
the signal cable.
2.2.6 Installation platform requirements
When installing on the installation table, the following conditions shall be ensured:

Make sure that there is space for the inlet and vent of the equipment so as to facilitate the heat dissipation of
the equipment chassis

Make sure the installation table has good ventilation and cooling system..

Make sure the mounting table is strong enough to support the weight of the equipment and its mounting
accessories.

Make sure the installation table is grounded well.
Other requirements such as shockproof, fireproof, waterproof, moistureproof, theft-proof, flooring, fireproof
facilities, grounding system, etc., please strictly comply with the "China telecom data room code", "China mobile
data room code", "China unicom computer room standard code".
