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 listed in Table 2-1 must be met when locating the equipment.
Table 2-1 Environmental conditions for the equipment room
Environmental conditions
Recommended range
Ambient temperature
-10°C to 55°C (derating from 40°C)
Humidity
≤ 90%RH, no condensation
Dust density
≤ 1mg/m
3
Sunlight
No direct sunlight
Corrosive materials
No pollutants, such as salt, corrosive materials, and smoke
Vibration
≤ 1.5m/s²
Harmful organisms
None
Mould
None
Dampness
The shelter should be 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.
Cabling
If top cabling is used, wiring rack should be provided in the equipment room. It is recommended that the wiring rack
be at least 300mm above the equipment. For bottom cabling 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 laid separately from DC cables and signal cables.
Antistatic
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 or antistatic ceramic tile is highly recommended for the equipment room. The
antistatic earth resistance should be no
greater than 10Ω. Care should be taken regarding antistatic during equipment
unpacking, transportation and operation.
