Product Description

The SC 4812ET BTS consists of an RF Cabinet that is an outdoor, weatherized version of the SC 4812T. The RF cabinet is powered by 27 VDC and each cabinet has the capability to support up to 4 carriers (at 3 sector) or 2 carriers (at 6 sector). An optional outdoor, weatherized Power Cabinet that provides AC/DC rectified power and battery back–up is also available. An air to air heat exchanger is used for conditioning each cabinet, except in the LPA area of the RF cabinet which uses blower fans to draw outside air over the LPAs.

The SC 4812T utilizes a new RF “Trunking” technique that provides shared power between sectors and increased RF output capability. The SC 4812ET will support additional expansion cabinets to add more carriers. Duplexer/Directional couplers will be standard equipment for the SC 4812ET BTS.

The RF Cabinet houses the fan modules, Combined CDMA Channel Processor shelf (C–CCP), Linear Power Amplifiers (LPA) modules, LPA trunking backplane, Bandpass 2:1 & 4:1 Combiners, Duplexer/Receive Filter/Directional Couplers (DRDC) and a DC Power distribution assembly. The Power Cabinet (PC) provides +27 V DC distribution and battery backup for the SC 4812ET. The Power Cabinet houses batteries, battery heaters, rectifiers, an AC Load Center (ACLC), a power distribution assembly, and two duplexed GFCI convenience outlets.

Overview

The major components which make up the Motorola SC 4812ET RF Cabinet (see Figure 1-2) and Power Cabinet (see Figure 1-7) system are illustrated in this section.

CAUTION

A service tent [reference: Pelsue Cabinet Mounted Service Tent; Pelsue (800–525–8460) P/N CM564866M] must be in place prior to opening the main doors of the SC 4812ET RF or Power Cabinet during times of inclement weather (rain, snow, sleet, or hail). This will prevent moisture from being drawn into the electronics by internal fans and damaging the equipment.

A service tent [reference: Pelsue Cabinet Mounted Service Tent; Pelsue (800–525–8460) P/N CM564866M] with a heater is required to service the SC 4812ET RF Cabinet when temperatures are below –10 degrees C (14 degrees F). Temperatures inside the tent should be above 0 degrees C (32 degrees F) prior to opening the main cabinet door. This will prevent a rapid temperature change to the electronics which could result in site outage.

External Blower Assembly (EBA)

The External Blower Assembly (see Figure 1-5) is a modular unit that provides cooling to the LPA’s, two blowers are used in the RF Cabinet.

Figure 1-5: External Blower Assembly (EBA)

CAUTION

The EBA contains two blowers and provides cooling that is VITAL to prevent service outage and possible damage to the LPAs. Since the SC 4812ET can continue to operate normally with one functional blower in the EBA, the EBA should not be removed until the replacement EBA is onsite. Then, the EBA is replaced as a unit while the RF cabinet is running. The replacement must be done within 3 minutes to prevent damage to the LPAs. Refer to the SC 4812ET FRU Guide for details regarding FRU replacement.

This chapter covers the SC 4812ET BTS site preparation recommended guidelines.

Installation sites can be classified into one of the three following categories: Indoor, Rooftop or Outdoor.

All applications will have common requirements and considerations. Differences between the location site requirements will be covered throughout the installation section. The following information is meant to serve as a guideline and can be impacted by site specific considerations.

Indoor Location

WARNING

Every effort should be made to provide a safe working area for all installation and service personnel.

CAUTION

The mounting surface must be flat. Door closure problems may occur if the cabinets are not installed on a flat surface.

IMPORTANT

The following items should be considered when choosing an indoor location for the SC 4812ET BTS:

– A permanent location is more desirable than a temporary one. – The cabinets should be placed in a location with appropriate

Care should be taken to ensure that the AC power pedestal does not interfere with the future addition of expansion or optional equipment service area.

– Adequate ventilation must be available to dissipate heat loads of

7,500 Watts (25,600 Btu / hr) for the RF Cabinet and 3,000 Watts (10,300 Btu / hr) for the Power Cabinet (a total of 10,500 Watts; 35,900 Btu / hr), and maintain a maximum temperature of no greater than 50 Deg C (122 Deg

– The AC meter and main disconnect should not be mounted to either

cabinet.

– Locations should be selected that will minimize accidental or

intentional vandalism. Do not select a location that is, or may be, subject to submersion (i.e. diversion channels, sub–basements, etc). While the RF and Power Cabinet are well insulated from the environment, they will not tolerate submersion.

– There should be adequate clearance through doors and passageways

to allow movement of the cabinet from the delivery area to the installation site.

– Verify, prior to final site selection, the availability and accessibility

to good grounding (ground system resistance must be less than 10 Ohms, with 5 Ohms or less being the goal; see ”Recommended Documentation” for Grounding Guidelines), RF cabling, Telco wiring, and 208–240 VAC power.

– There should be adequate space available for the future addition of

expansion or optional equipment.

– The location of an AC power pedestal to mount the AC meter, main

breaker, generator plug, etc. (if necessary), is at the installers option.

– Every effort should be made to minimize the separation distance

between the RF and Power Cabinet (see Table 2-1) for maximum cable length between cabinets

F).

NOTE

– 3.65 m (12 ft.) is the length of the # 2/0 AWG DC Power Cable supplied with the Power Cabinet. – If a custom cable is used, 610 mm (2 ft.) should be reserved at both ends to allow for the distance from the

edge of the cabinet to the power terminals.

Rooftop Location

In addition to the Indoor location considerations, the following

additional items should be considered when choosing a Rooftop location:

WARNING

Roof load carrying limits must be reviewed and an appropriate support structure must be installed to support the cabinets as required.

CAUTION

The cabinets must be elevated sufficiently above the roof surface to prevent water from puddling around its base. Although the cabinets are well insulated from the environment they will not tolerate submersion.

Loading Considerations (also see Table 2-2):

– A single SC 4812ET RF Cabinet can weigh up to 680 kg. (1500

lbs) and a single Power Cabinet enclosure can weigh up to 1590 kg. (3500 lbs) with the batteries installed (batteries are shipped separately). Expansion enclosures and optional equipment will add weight (refer to the introduction section of this manual for obtaining detailed information on the optional equipment).

NOTE

The Power Cabinet as shipped without batteries installed can weigh up to 544 kg (1200 lbs.).

– When the cabinet is to be roof mounted, be sure to consider the rain

and/or snow loading of the region when determining whether the roof can support the load.

Zoning requirements – that relate to building mounted equipment should be checked for any restrictions that may affect cabinet or antenna placement.

Adequate clearance through doors, passageways and stairwells to allow movement of the cabinet from the delivery area to the installation site.

Cabinet Weight Table

Site Preparation – continued

In addition to the Indoor location considerations, the following additional items should be considered when choosing an outdoor location:

– The cabinet should be placed in a location with appropriate

clearance from any obstructions. For minimum clearances see Chapter 1.

– It should be the practice of any installing company to acquire, in

advance of construction, the rights of way from landowners, and permits or approvals from public authorities. It is recommended that the BTSs be placed in servitudes, on dedicated (recorded) easements, or on property owned by the company. Unrecorded easements should be avoided.

– The cabinet should be easily accessible with adequate parking to

ensure craftsmen and vehicle safety. Also, place the cabinet where it will not create a visual or physical obstruction to either vehicular or pedestrian traffic.

– Locations should be selected that will minimize accidental or

intentional vandalism. The use of protective posts and/or fences should be considered when located near parking areas where vehicles may hit the cabinet.

– Every effort should be made to minimize the separation distance

between the RF and Power Cabinet (see Table 2-1).

Materials Needed

The following list of materials may vary depending on site specific requirements. If in doubt contact Motorola Cellular Support Center. The phone number is found in the Foreword of this manual.

Installation hardware is provided with the cabinets. (Refer to Chapter 1 for a description of this hardware).

Tools – Refer to Chapter 1 for a list of tools that will be helpful when installing the SC4812ET BTS.

Rooftop

WARNING

Roof load carrying limits must be reviewed and an appropriate support structure must be installed to support the RF and Power Cabinet as required.

CAUTION

The cabinet must be elevated sufficiently above the roof surface to prevent water from puddling around its base. Although the cabinets are well insulated from the environment they will not tolerate submersion.

. . . continued on next page

Apr 2001

SCTM 4812ET RF and Power Cabinet Hardware Installation Manual

DRAFT

Site Preparation – continued

Refer to Figure 2-5 and Figure 2-6 for proper position of mounting locations when designing the support structure.

Rooftop (Elevated)

New Concrete Pad

For most rooftop installations all of the connections to the cabinet will be made through the rear of the cabinet I/O area. For this reason, the cabinet must be set in place and bolted down prior to running any conduits or wiring. Conduit/wire routing will be discussed in Chapter 5.

Lightning protection is included in the cabinet. A good earth ground (ground system resistance must be less than 10 Ohms, with 5 Ohms or less being the goal) is required for the lightning protection equipment to perform properly. Refer to Motorola’s guidelines (Motorola Publication 68P81150E62) for details on the design of a grounding system. Conform to local electrical construction standards for conduit materials and sizing.

For a rooftop installation which is elevated sufficiently above the roof surface, most of the connections can be made through the bottom of the cabinet by terminating the conduit at the bottom of the rear I/O area. See Figure 2-6 for recommended conduit/cable entrance layout.

CAUTION

The mounting surface must be flat. Door closure problems may occur if the cabinets are not installed on a flat surface.

To help reduce the chance of damage caused by lightning strikes, it is required that a ground ring be constructed when the pad is built. See section titled ”Ground System Installation”.

Variations in pad construction methods may be required to comply with local conditions, practices, or building codes.

Install the grounding system, and electrical conduits (see Figure 2-3, Figure 2-4, and Figure 2-6) prior to pad construction. Refer to the Motorola guidelines (Motorola Publication 68P81150E62) for details on the design of a grounding system. Conform to local electrical construction standards for conduit materials and sizing. Refer to Table 2-6 and Table 2-7 for minimum bend radius of antenna cables and maximum number of cables in a conduit.

If it is desired to make cabling through the bottom of the cabinets, it is recommended that the conduits be positioned using the dimensions given in Figure 2-5 prior to pouring the concrete pad. Installation in this manner allows for the connections to the RF and Power Cabinet to be made through the bottom of the I/O area, although it may be desirable to make the antenna connections through the rear wall. For the connections that are made through the bottom of the I/O area, conduits and wiring can be installed prior to arrival of the cabinet.

Connection Materials

CAUTION

Conduits that are pre–installed in a concrete pad below grade must be capped at the time of conduit installation to prevent rainwater from collecting in the conduit.

WARNING

If a precast concrete foundation pad is used, the pad should be in place before the cables are installed. This will avoid an unsafe condition caused by personnel reaching under a pad, as it is lowered, to feed cable through the pad openings.

This section defines connection materials and specifications and may vary depending on site–specific requirements. If in doubt, contact Motorola Cellular Support Center (telephone number is found in the Foreword of this manual).

Concrete Pad and Ground System Installation

SCTM 4812ET RF and Power Cabinet Hardware Installation Manual

DRAFT

Site Preparation – continued

Installation Procedure:

Install the concrete pad and ground system as described in Table 2-9.

Step Action

1 Ensure that the pad location is firm and level. If the ground around the location is not firm, compact

the soil and construct a level base for the pad using a minimum of six inches of gravel or per local code requirements.

2 Dig trenches 610 mm (24”) deep (minimum), and wide enough to accommodate the ground ring and

conduits.

3 Install conduits. Recommended locations are shown in Figure 2-6. Refer to Table 2-6, and Table 2-7

for minimum bend radius of Foam Heliax and maximum number of Heliax in a conduit.

4 Install 152 mm (6”) concrete pad frame with integral rebars and dry wells. Refer to Figure 2-6 for pad

dimensions. 5 Install #3 BSWG (#2 AWG; 35 mm2) solid tinned copper perimeter ground ring (see Figure 2-3). 6 Exothermic weld #3 BSWG (#2 AWG; 35 mm2) solid tinned copper wire from concrete pad rebar to

perimeter ground ring. 7 Install copper clad steel ground rods. 8 Exothermic weld perimeter ground ring to steel ground rods. 9 Install three #3 BSWG (#2 AWG; 35 mm2) solid tinned copper wires, exothermic welded to perimeter

ground ring, for BTS master ground, Power Cabinet master ground, and for antenna tower ground

straps.

Table 2-9: Concrete Pad and Ground System Installation Procedure

NOTE

For sites with multiple cabinets an additional #3 BSWG (#2 AWG; 35 mm2) solid tinned copper wire

must be installed for each additional cabinet.

10 Fill the trenches in the area of the pad with soil and tamp. 11 Pour concrete until level or slightly above the concrete forms. Puddle the concrete along the edges of

the forms. Use a straight piece of lumber or equivalent as a guide to level the concrete.

12 For additional finishing, wait until the pad no longer looks as if water is standing on top and trowel

smooth.

13 After the second day the concrete forms can be removed. 14 The concrete mounting pad must cure adequately before the cabinets may be installed.

The RGPS Head requires specific mounting considerations in order to properly observe the GPS satellites.

– The mounting pipe for the RGPS Head should be mounted

vertically with less than five degrees of tilt.

– The RGPS Head needs to have a clear view of the sky, preferably to

within ten degrees of the horizon in all directions. The less sky that can be observed the fewer the number of potential satellites that can be tracked and hence the poorer the RGPS performance.

– For general operation, the RGPS Head needs to be able to

continuously track signals from at least four (4) GPS satellites. It is theoretically possible to operate the BTS with only one GPS satellite visible, however, operating in this mode it is not recommended and requires an accurate site survey.

Apr 2001

SCTM 4812ET RF and Power Cabinet Hardware Installation Manual

DRAFT

Site Preparation – continued

– Place the RGPS Head where RF obstructions of the sky are

minimized. The “sky” includes everything to within ten degrees (10°) of the horizon in all directions. RF obstructions includes

buildings, towers, snow, foliage and debris.

– Separate the RGPS Head from radiating sources. Excessive RF

energy can degrade the RGPS head’s ability to observe the GPS satellites. The RGPS head receives on the GPS L1 frequency of

1575.42 MHz and has filters incorporated within to minimize the effects of potential RF interference, however, strong radiators can overwhelm the filters, thus degrading the units reception capability.

– The RGPS Head is rated for ambient air temperatures from –40 Deg

C to +50 Deg C, and has ratings for Humidty, Shock, Waterproof, UV Light Resistance, Vibrations, Salt, Fog, ESD, EMI, and Altitude.

– The RGPS system will support up to 2000 feet (610 m) of overall

cable length from the RGPS Head to the last connected base station. If a long cable run needs to be broken into pieces, minimize the number of breaks in the cable.

have a heater pad above it), terminate the long cable with the terminating connector removed from the factory installed cable in step 2.

6 Repeat this procedure until all heater pads are installed, then proceed to the battery

installation.

IMPORTANT

After all of the heater pads have been installed and cables connected, dress the cables behind the battery shelves in each battery compartment. When dressing cables, consideration should be given to future accessibility of the cables should a heater ever need to be replaced. Do not zip tie cables to battery shelves or each other. Also, do not tangle cables in one another. Ensure cables are routed such that a heater pad cable connector for one shelf can be pulled up from the shelf below it without having to remove the batteries below.

Alarm Signal Specifications

Table 5-6: External Alarm Connector Characteristics and Requirements

Function

ALARM connections provide Customer Defined Alarm Inputs and Outputs. The customer can connect RF Cabinet site alarm input sensors and output devices to the RF Cabinet, thus providing alarm reporting of active sensors as well as controlling output devices.

Connections

Table 5-6 describes the characteristics and requirements for the inputs (each of which consists of a single 2–wire pair) and outputs (each of which consists of two 2–wire pairs; COM–NC and COM–NO).

Inputs Outputs

To ensure proper operation, each wire pair to be used must be connected to an external transducer that

provides a dry contact.

– A closed contact including cable resistance must

be 1K ohms or less.

– An open contact including cable leakage must be

50K ohms or greater.

Either of the above states can be defined by the customer in system software as an alarm condition.

Alarm and Span Line Cable Pin/Signal Information

Table 5-7 lists the complete pin/signal identification for the 50–pin punch block.

The customer output device control inputs connect between the common (COM) and either the normally closed (NC) or normally open (NO) contacts of a relay.

– Relay contacts are load rated for a maximum of

1A @ 30V DC and 1A @ 30V AC resistive.

The toggling of the relay contacts to the opposite state is controlled by system software.
