4 Space Requirements

The following sections specify the space requirements for the RBS 3116. Allmeasurements are in mm.

4.1 Installation Requirements

A space of 1000 mm is recommended in front of the RBS 3116 to avoidobstructing the door. This also ensures adequate working space and sufficientairflow.

Installation and maintenance require that the door can be opened at least 120�.100 mm free space is needed behind the cabinet.

If the RBS 3116 is located next to another cabinet of the same depth, a 50mm space between the two cabinets is required to enable the door to open.However, if the RBS is placed beside a wall, then a 300 mm space is requiredto the left of the cabinet to enable the door to open 120�. Figure 3 on page 6shows the installation requirements.

A tent can be placed over the outer cabinet during service to protect theequipment from bad weather.

5.5 Radio Frequency Electromagnetic Exposure

This section provides information on Radio Frequency (RF) ElectromagneticField (EMF) exposure from a typical antenna connected to the RBS 3116.

5.5.1 Compliance Boundaries for Electromagnetic Exposure

The compliance boundary defines the minimum separations that must be keptbetween the antenna and a person to ensure that the ICNIRP¹ and FCC² RFexposure limits are not exceeded.

¹ICNIRP,‘‘ Guidelines for limiting exposure to time-varying electric, magnetic,and electromagnetic fields (up to 300 GHz)’’, International Commission onNon-Ionizing Radiation Protection, Health Physics, vol. 74, no. 4, 1998.

²FCC, Code of Federal Regulations CFR title 47, part 1.1310 ‘‘Radiofrequencyradiation exposure limits’’, Federal Communications Commission (FCC),August 1997.

Ericsson has performed RF exposure assessments of typical configurations ofthe RBS 3116 with a recommended antenna. Table 7 on page 10 shows theresulting dimensions, in meters, for a compliance boundary for both publicand occupational exposure.

The compliance boundary is defined as a cylinder surrounding the antenna,see Figure 5 on page 10. The antenna is not located at the center of thecylinder. Instead it is located almost at the edge, facing towards the center ofthe cylinder. The distance between the rear of the antenna and the cylinder isthe “Distance behind antenna”. The height of the cylinder is the antenna heightplus equal distances above and below the antenna.

Note: Table 7 on page 10 shows an example for a typical antenna. Asthe antenna field distributions will differ, complete calculations ormeasurements may be necessary to establish the compliance boundaryfor other configurations chosen by the customer. For further informationon calculation methods, see Radio Frequency Electromagnetic Fields,Reference [3].

Note: The expanded uncertainty (k=2) is ±2 dB for the underlying calculationsof the power density used for assessment of the compliance boundarydimensions listed in Table 7 on page 10.

Characteristics of the antenna recommended for typical RBS 3116configurations are listed in Table 8 on page 11.

9 Climate System

The climate system consists of a CLU located inside the door, three internalfans located in the inner cabinet, and a heater located at the top of the cabinet.

The fans in the inner cabinet provide internal airflow to the plug-in units and arecontrolled by the FCU.

The CLU mainly consists of the following:

• An air-to-air heat exchanger and fans for the internal and external aircircuits respectively

• A Climate Control Unit (CCU), which controls and supervises the climateunit

The heater is controlled by the CCU for cold starts when the ambienttemperature is lower than the minimum operating temperature. The heater isalso used in very cold conditions when additional heating is needed to keep theinternal RBS temperature within the specified limits.

10 Power System

The incoming nominal power supply voltage is 100 – 250 V AC. The RBS3116 transforms the incoming power to 48 V DC, which is the voltage thatruns the RBS units.

Note: The site AC power supply to the RBS 3116 must be of over-voltagecategory 2.

The incoming voltage alternatives are shown in Table 18 on page 35.

10.1 Fuse Recommendations

This section contains information about fuse/circuit breaker recommendations.

The recommendations given in this section are based on peak powerconsumption and gives no information on power consumption during normaloperation. Power supply of customer equipment housed in cabinet isconsidered in the recommendations.

For power consumption during traffic, refer to Section 10.2 on page 38, wherethe typical and high-load power consumption are given for each configuration.

As a feature, the RBS has a built-in Class I (Type 1) Surge Protection Device(SPD) to protect the equipment in case of lightning and network transients.The recommended fuse or circuit breaker rating is therefore dimensioned fornot tripping the fuse or circuit breaker in case of SPD operation. Only if it isaccepted that fuses or circuit breakers trip in such situations, the minimum fuserating could be taken into account.

Table 19 on page 36, Table 20 on page 36, Table 21 on page 37, and Table22 on page 38 show the fuse or circuit breaker recommendations for differentcombinations of use of heater and service outlet. If the recommended fuse sizeis not available a larger size must be used.

The recommended melting fuse type is am-gL-gG in accordance with IEC60269-1. Circuit breakers must comply with Curve C tripping characteristics, inaccordance with IEC 609 34.

(1) The minimum fuse rating corresponds to peak load typically occurring during initial batterycharging. These fuse sizes can only be used if it is acceptable that fuses are blown due tolightning or network transients. Selectivity is not granted.(2) The recommended fuse rating take into account that external fuses are not to be blown due tolightning or network transients. For an RBS with an internal fuse or circuit breaker, selectivityis granted.(3) An absolute maximum fuse class in accordance with RBS design restrictions.(4) Three-phase Y-load means that the load is connected between phase and ground.(5) Three-phase Delta-load means that the load is connected between two phases.(6) If a circuit breaker is used, 40 A Curve C is applicable.

10.2 Power Consumption

This section contains the power consumption figures for the RBS. The powerconsumption figures shown in this section refer to normal operation duringtraffic and use of the latest hardware revision.

Typical power consumption values are based on a realistic and typical trafficdistribution that corresponds to an average output power of 40%. Coolingconditions are based on an annual temperature distribution for the Frankfurt(Germany) climate zone. Optional equipment and service outlet is not included.

The high-load power consumption values correspond to 100% of maximumoutput power. Cooling conditions are based on statistical maximum temperaturefor the Frankfurt (Germany) climate zone (+30�C). Optional equipment andservice outlet is not included.

12 Alarms

This section describes the external alarms that are available for the RBS 3116.

Customer-Specific External Alarm

The RBS equipped with External Alarm Unit (XALM) (optional) provides eightexternal alarm input ports to be used for customer-specific purposes. The RBSalso handles four remote control signals.

An alarm can be triggered by two different alarm conditions:

• Closed loop condition, called Normally Open (NO)

NO means that an alarm is triggered when an open switch is closed.

• Open loop condition, called Normally Closed (NC)

NC means that an alarm is triggered when a closed switch is opened. NCis the default alarm condition.

The customer can configure the alarm condition.

Predefined External Alarms

The RBS equipped with an XALM handles two predefined external alarms(optional), in addition to the eight external alarm input ports.

The predefined alarms are:

• Fire Alarm

• Smoke Detector Failure

Open door alarm is standard and reported by the CLU.
