l
The number of installation engineers should be based on the specific engineering schedule
and the installation environment. In general, arrange for three to five installation engineers.
2.2 Checking the Installation Environment
This topic describes the requirements for checking the hardware installation environment.
2.2.1 Checking the Equipment Room Structure
Room construction, room structure, heating and ventilation, power supply, illumination and fire
control are related to the equipment room. The engineering design of these items must not only
meet the requirements for the equipment room, but must also comply with the local standards
and regulations. It must also meet the regulations and requirements of the room structure and
design in the field of special technique design.
Check the equipment room structure with regard to the following aspects:
l
The minimum height of the equipment room refers to the net height below the beam or the
ventilation pipe. The height must not be less than 3 m (9.84 ft).
l
The floor of the equipment room must be semi-conductive and dust-proof. An antistatic
movable floor is recommended. Pave the movable floor tightly and solidly. The horizontal
tolerance of each square meter must be less than 2 mm (0.08 in.). If the movable floor is
not available, use the static electricity conductive floor material, with the volume resistivity
ranging from 1.0 x 10
7
ohm-m to 1.0 x 10
10
ohm-m. The static electricity conductive floor
material or the movable floor must be grounded for conducting the static electricity. You
can connect the floor material or the movable floor to the grounding unit by using the current
limiting resistor and the connection line. The resistance of the current limiting resistor is 1
megohm.
l
The door and windows must be installed with dust-proof plastic sealing tapes. It is
recommended to install the windows with double-layer glass and seal them strictly.
l
The wall must be processed by using wallpaper or flat paint. Do not use pulverized paint.
l
Cables must be laid along grooves. The inner side of the grooves must be smooth. The
reserved length and width of the grooves, and the number, position and dimensions of the
holes must comply with the requirements for installing the device.
l
It is recommended not to lay water supply pipes, drainpipes or storm sewers across the
equipment room. Do not install the fire hydrant inside the equipment room. Install the fire
hydrant in the corridor or near the staircase where convenient access is possible.
l
The air conditioner is installed in a proper position where the air does not blow directly at
the device.
2.2.2 Checking the Equipment Room Conditions
To ensure good working conditions for the device, take related measures so that the equipment
room conditions meet the requirements for proper device running.
Check the equipment room conditions with regard to the following aspects:
l
The illumination of the equipment room must meet the requirements for device
maintenance. Ensure that the following three illumination systems are available: routine
illumination, standby illumination, and emergency illumination.
