Chapter 2 Installation Preparation
This chapter introduces installation requirements, storage conditions, installation preparation and unpacking
inspection.
2.1 Installation Requirements
2.1.1 Environmental Requirements
The environmental conditions of the equipment room must meet the requirements listed in Table 2-1.
Table 2-1 Environmental conditions for the equipment room

Dampness
Waterproof
The equipment may be prematurely damaged if dust or sand accumulates in it. The following measures are
recommended for dirty environment:
1. The equipment should be installed in an airtight and air-conditioned room. The air conditioner filter should be
adequately maintained without being obstructed. To reduce the dust in the equipment room, unattended equipment
room is recommended.
2. Clean the air filter periodically to provide clean air.
2.1.2 Layout Requirements Of The Equipment Room
Air exhaust and ventilation
When the power supply is working, the main exothermic part is the rectifier. To ensure free airflow around the power
supply system, an 800mm clearance must be kept in front of the system and 800mm behind.
Cabling
The top cable entry system are all introduced from the top of the cabinet, therefore wiring rack should be provided in
the equipment room for top cable entry system, which is recommended to be at least 300mm above the equipment.
For bottom cable entry system, cable trough should be provided in the equipment room, which should be no wider
than the spacing between the equipment mounting holes.
Note
To prevent electric coupling, AC cables should be run separate from DC cables and signal cables.
Installation surface
The installation surface is supposed to be cement floor or incombustible metal subrack.
Antistatic requirement
As for antistatic requirement, the absolute value of the static voltage of the equipment, wall and people to the ground
should be less than 200V. Raised floor is highly recommended for the equipment room. The antistatic earth
resistance should be not
greater than 10Ω. Care should be taken regarding antistatic during equipment unpacking,
transportation and operation.
