The functions of the major components at the bottom of the BTS3012AE cabinet are as follows:

l The GPS cable hole is used to lead the GPS clock signal cable. The GPS clock signal isused as the primary reference clock signal for the cabinet.

l Cable hole for the IBBS power cable is used to lead the GND cable and the 48 V power

cable for the IBBS cabinet.

l Cable hole for external power input leads the external AC power cables (L1, L2, L3, and

N), PGND cable, and equipotential cable for the IBBS cabinet.

l Cable hole for the transmission cable or signal cable leads the cable for the IBBS door

control sensor, cable for the external battery temperature sensor, Boolean value input/output

cable, BITS clock cable, and monitoring signal cable for combined cabinets.

l The cable hole for the RF jumper is used for the cabling of the 1/4-inch jumper and the 1/2-

inch jumper.

2.5 BTS3012AE Fan Filter UnitThe fan filter unit is installed on the front door of the BTS3012AE cabinet. The airflow from

the environment is absorbed and filtered by the fan filter, and then used for the cabinet heat

dissipation. If the fan filter unit is faulty, an alarm is reported to the DTMU.

Appearance

Figure 2-7shows the fan filter unit.

2 BTS3012AE Cabinet

BTS3012AE

Figure 2-7Fan filter unit

Components

The components of the fan filter unit are as follows:

l Control board: The control board uses the DC power to drive two centrifugal fans and

collects the temperature inside the cabinet to adjust the running status of the fans. The

control board reports the board information through the RS485 port and the Boolean signal.

l

Fan filter: The fan filter is made up of expanded PolyTetraFluoroEthylene. The fan filterfeatures the ventilation capability with dustproof and waterproof capabilities.

BTS3012AE




10/26

l Fan: Two centrifugal fans vertically arranged inside the fan filter are used to accelerate the

ventilation. The fan filter unit must use the fans with DC pulse-width modulation (PWM)

speed control.

PrinciplesThe fan filter unit absorbs and filters the airflow from the environment through the fan filter,

uses the centrifugal fans to accelerate the ventilation and cool down the airflow inside the cabinet,

as shown in Figure 2-8. The control board uses the sensors to collect environment parameters,

controls the running status of the fans in real time, and reports the board information.

Figure 2-8Principles of fan filter

NOTE

There are two types of air circulation in the fan filter unit, a large one for the cabinet heat dissipation and

a small one for the relative humidity in the fan filter unit.

2.6 BTS3012AE Batteries

When the external power supply for the BTS fails, batteries are used to sustain the running of

the BTS for a period of time. The BTS3012AE provides a built-in battery cabin and an external

battery cabinet.

Built-In Battery Cabin

The BTS3012AE cabinet has a 48 V DC 150 AH battery cabin and a 48 V DC 50 AH battery

cabin. The maximum configuration of the batteries is 200 AH. In S4/4/4 configuration mode,

the built-in 200 AH battery can provide power for four hours when the traffic volume is normal.

The built-in storage battery of the BTS3012AE has three configuration modes: 100 AH, 150

AH, and 200 AH. The use of built-in storage battery depends on your decision.

The 100 AH and 150 AH configuration modes are designed for Cabinet (A). The 200 AH

configuration mode is designed for Cabinet (B).

The 100 AH and 150 AH configuration mode uses four 100 AH/12 V or 150 AH/12 V storage

batteries in serial connection. The 200 AH configuration mode uses eight 100 AH/12 V storagebatteries. The eight batteries are divided into two groups and each group is composed of four

batteries. The four batteries in each group is in serial connection and the two groups are in parallel

connection.

External Battery Cabinet

The external battery cabinet can provide up to 600 AH power. In S4/4/4 configuration mode,

the external battery cabinet can provide power for more than four hours when the traffic volume

is normal.

NOTE

The external battery cabinet is optional.

2.7 Cable Distribution at the Front of the BTS3012AECabinet (for FFU)

The cables at the front of the BTS3012AE cabinet are RF cables, monitoring signal cables, signal

transfer cables, E1 cables, power cables, and PGND cables.

NOTE

Use the combination mode in the DFCU first when the cabinet using the DFCU is configured in S4/4/4

cell configuration. Because the DTRU is not in combination mode, the combining short-circuiting cables

(R19R30) are not required.

2.8 Cable Distribution at the Back of the BTS3012AECabinet (for FFU)

The cables at the back of the BTS3012AE cabinet are power cables, monitoring signal cables,

signal transfer cables, and PGND cables.
