2.9 Installing Cable

2.9.1 Power Device Installation

The electric power construction is a process to supply the power to the base station.

When the power is supplied to the base station, and if the power is supplied to the inside of

the building, the required power should be secured first by consulting with the owner of the

building about the quantity of the power for use, before the electric power construction is

performed. If the power for use runs short, the power should be supplied by extension or

additional supply of the power.

The power supplies are classified into the power supply for the central office and the power

supply for communication. The power supply for communication is the electric energy that

supplies to the establishment for communication, and the power supply device for

communication is the power supply device for the communication loading facility.

The power supply device of the base station is configured with the followings based on the

AC distributing switch, rectifier, and storage battery.

Figure 2.63 Power Device Configuration Diagram

Take the caution below when installing the power device:

y Maintain proper interval between the power device and the baseline location, a wall,

and a pillar according to the installation plan.

y The rectifier should be installed/placed over 1.5 times of the rectifier width away from

the wall or the neighboring obstacle. However, when there is no difficulty in the

operation, this caution is not applicable.

y Arrange and construct the rectifier with the shortest distance between the battery

charge/discharge line and the load supply line.

y Construct the power equipment horizontally and vertically.

y The fuse for each switch rack in the DC control board should have a rated capacity.

y Embed the anchor bolts and use the insulation bushing to fix the power device on the

floor. In this way, the power device can maintain insulation from the floor.

y Install the battery close to the rectifier as much as possible.
