4. Health and Safety

The unit weighs approximately 13Kg (29lbs); so care should be exercised when lifting and moving

the product.

Appropriate safety equipment should be used at all times.

If using a hoist to lift the unit up a mast, attach the rope to the carrying handle at the top of the unit,

see Figure 4.1 for details.

4.1 Carrying Handle Location.

125-10001-015 Issue 1.5 Date 20/04/2011



5. Choosing a Site for the Radiohead

The remote radio head is a heat dissipating unit and so it will run at a temperature notably above the

local ambient. If the temperatures of the unit become excessive the unit will run less efficiently,

therefore the unit must always be mounted vertically as detailed in these instructions, in an area

with unrestricted airflow/ventilation.

Solar radiation can also significantly increase the temperature of the unit and so should be taken

into consideration when choosing a location for the unit. In particular it is recommended that the

finned surfaces should be shaded from the sun. Ideally in the Northern Hemisphere the unit should

be located on a North facing wall where it is shaded from the sun; or in a location where an adjacent

object or building will offer similar shade. In the Southern hemisphere the unit is should ideally be

located on a South facing wall.

In areas where the temperature can be considered to be moderately warm, or the ambient

temperature could reach temperatures of approaching 30°C or above and shade is not given to the

unit by any of the adjacent walls or buildings then a solar shield should be fitted to the unit.

7.1. Mounting the RRH to a Pole

7.1.1 Attach the wall mounting brackets to the RRH as described in Section 1.

7.1.2 Attach studs supplied to the outer pair of holes on a pole mounting bracket as

shown in Figure 7.1. The nuts on the outer faces of the brackets must be

assembled with Spring and Plain Washers, and the nuts on the inside faces

assembled with Plain Washers only.

Figure 7.1 Assembling Stud and Fixings to Mounting

Bracket

125-10001-015 Issue 1.5 Date 20/04/2011



7.1.3 Tighten the pair of nuts against the brackets to a torque of 5Nm.

7.1.4 Thread a nut and washer onto the free end of each stud as shown in Figure 7.1,

ensuring that these nuts will not foul the second bracket before it has been

tightened against the pole.

7.1.5 Position the bracket at the required height and orientation, and slide the second

bracket into position over the free end of the stud.

Note: You should always install the upper brackets first – and the hooks on this set should be

directed upwards.

7.1.6 Secure the brackets in position using a washer and nut on the outside face of to a

torque of 5Nm, as shown in Figure 7.2.

7.1.7 The inner nuts installed in step 7.1.4 should now be wound out to secure the

second bracket into place (so that the assembly looks symmetrical) and tightened

to 5Nm.

125-10001-015 Issue 1.5 Date 20/04/2011



7.1.8 Repeat steps 7.1.2 to 7.1.7 for the lower bracket assembly, positioning the pair of

brackets approximately 350mm beneath upper set of brackets, with the hooks

facing downwards and the nuts only finger tight (so that the brackets don’t fall

down the pole but can be easily moved).

7.1.9 Position RRH so the slots in the top wall mounting bracket locate over the hooks

on the upper pole mount bracket assembly (See Fig 7.3).

7.1.10 Slide the lower pair of pole mounting brackets down the pole until the hooks

locate into the slots on the lower unit mounting bracket.

7.1.11 Secure the lower pair of pole mounting brackets firmly in position as per the 7.1.6

and 7.1.7.

7.1.12 Secure the unit to the pole mounting brackets using the M8 screws, washers,

spring washers and nuts provided, to 5Nm, as shown in Figure 7.4.

8. Cable Attachment to the RRH

All caps or bungs should be removed just prior to connection, after mounting of the unit to the wall

or pole. Optical [refer to AceAxis document 125-10001-018] and DC connections should not be

made if the environment or weather is likely to allow water or dust ingress to the unit as these

connection points are only IP rated once the seal is made. The connection procedure of the cables

could be as follows (see Fig 8.1 for RRH connector identifications):

8.1.1 Earth Cable.

Attach an approved, correctly terminated Earth Cable (AWG10 minimum diameter), using the

2 x M6 earth screws and washers provided. Tighten to 5Nm.

Note: It is critical that this is the first cable connected to the RRH. Under no

circumstances should a unit be commissioned without adequate grounding.

8.1.2 Antenna Port Cables (1-2).

Attach the two antenna cables, in order, with N type connectors and tighten the coupling nut

to 1Nm.

Note: It is not recommended that any ports remain unterminated, as this could lead to

degradation of the connector material if left exposed to the environment and prevent

easy installation of a cable at a later date.

8.1.3 Optical Fiber Port (1-2).

Clip the LC connector into the relevant SFP, and slide the rubber sealing boot up the cable

and into the sealing port [refer to AceAxis document 125-10001-018].;

125-10001-015 Issue 1.5 Date 20/04/2011



Note: The correct SFPs should have already been installed into the RRH (in a suitable

anti-static environment prior to mounting). If a port is not to be used for any reason, the

weather resistant bung should remain in place and be kept, sealed to prevent any ingress

of dust or moisture.

8.1.4 Remote Electrical Tilt (RET): Optional Connection.

Line up the relevant cable so that the electrical connections and guide pin in the connector are

all aligned with those in the receptacle. Insert the connector into the receptacle on the RRH

and tighten the screw thread until the cable is secured in place and the relevant seal has been

made.

Note: If the RET connection is not used, then the shipping cap must be left securely in

place to prevent the ingress of water or dust.

8.1.5 External Alarms: Optional Connection.

Line up the relevant cable so that the electrical connections and guide pin in the connector are

all aligned with those in the receptacle. Insert the connector into the receptacle on the RRH

and tighten the screw thread until the cable is secured in place and the relevant seal has been

made.

Note: If the RET connection is not used, then the shipping cap must be left securely in

place to prevent the ingress of water or dust.

8.1.6 DC Power Connection.

Attach the DC power connector (-48Vdc) using an appropriately assembled Harting cable

assembly. The connector has a pivoting latch that should be pulled across and locked into

position onto the two locating dowels (See Appendix A for more details).

125-10001-015 Issue 1.5 Date 20/04/2011



8.1.7 Sealing All Used Connectors

Whilst these units have been designed and qualified to an appropriate standard to ensure it is

suitably protected against ingress during its operational life, AceAxis Ltd are unable to

control the standard and consistency of installations. Subsequently it is strongly recommended

that appropriate environmental sealing tape is applied to all antenna connections, the fiber

optic connections, DC power connection and all other optional fitted cables / connectors to

prevent water ingress or corrosion of the connector joints/threads.

Appendix A. DC Supply Connection

The minimum tools required to assemble a Harting DC Connector are:

• 2mm Hexagonal Allen key.

• Wire strippers.

A.1 DC Supply Connector

The standard power connector is a Harting Han Q, the connectors are both wired as follows (Table

A1). Care should be taken to observe the correct pin location on the connector in the case of

reverse-sex contacts.

Pin Attribute 1 Positive Return (Red) 2 Negative Supply (Black) 3 On the mating (RRH) connector this pin is connected to the Chassis Earth (Green/yellow)

Table A1: DC Supply Pinout Conventions

The cable housing can accept cable gauge AWG 8-12. A cable sheath should be used for outdoor

deployments that will provide an environmental seal between the connector and the cable. Either

can be fitted although the cable gauge determines the maximum length of power cable that can be

supported (See A2 for more details).

For convenience the manufacturer’s part numbers (for a recommended Cable Connector assembly)

are listed below (Table A2). The correct connector must be used to give the IP65 or higher

protection.

Part Description Harting Part Number

Cable Gland 20 mm 1900 000 5084

Table A2: Harting Connector Part Numbers

125-10001-015 Issue 1.5 Date 20/04/2011



A.2 Recommended Maximum Power Supply Cable Length.

The power cable should be AWG 8-12 minimum gauge, specified to NEC/CEC.ANSI/NFPA70.

The cable length should be sufficient to make sure that the cable voltage drop under highest current

load does not increase the input voltage at the RRH above -36V.

The maximum allowable cable length can be calculated using the following equation;

Maximum cable length (m) = 1000 × (VPSU - 36) / (IMAX × 2 × CableRES)

Where:

IMAX is the maximum current

VPSU is the source voltage (in this case 48V)

CableRES is the cable resistance* (expressed as Ω/Km).

* This value will depend upon the manufacturer and gauge of cable.

The following table (Table A3) shows the range for each AWG cable size.
