5 Installing the iRU4438 iRRH
This section provides the procedure for installing the iRU4438 iRRH in remote
locations such as on towers, poles, masts, walls, roofs, or other structures utilizing a
universal mounting assembly.
Instructions for making connections to external interfaces, cabling, grounding and
power are also provided.
5.1 Assembling cables
5.1.1 Verify Operator supplied 110/220 V ac power cable
The Operator supplies and pre-assembles the 110/220 V ac power connection cable.
We recommend using a 14 AWG, round, 2-wire with ground, shielded cable rated at
300 V minimum. The female plug (manufacturer's part no. BD-03BFFA-LL7001) for
connection at the iRU4438 iRRH end is also provided by the Operator. The connection
configuration for the supply side of the power cable is determined by site specific
requirements.
5.1.2 Verify Operator supplied fronthaul Ethernet cable
The CAT-5 Ethernet cable is supplied and pre-assembled by the Operator. A cable
gland may be pre-installed on the Ethernet cable, or may be installed on a CAT-5
cable, in the order shown in Figure 5-2. If the cable gland has a lock nut installed on
it, it must be removed before installing the cable gland to the fronthaul entry port.
The cable gland screws directly into the fronthaul port on the bottom of the iRU4438.
A gasket seals the cable gland at the fronthaul port. The sealing nut is then handtightened to complete the weatherproof seal.
Figure 5-2 CAT-5 Ethernet cable gland assembly
5.1.3 Verify Operator supplied grounding cable
The operator pre-assembles the grounding cable prior to routing to the iRU4438 iRRH.
The grounding cable and ground bonding hardware is supplied by the Operator.
However, the grounding terminal lug is supplied with the iRU4438 iRRH.
iRU4438 iRRH Product Descripton and Installation Guide
5-1
Installing the iRU4438 iRRH
NOTE
The grounding cable to the iRRH should be 3.9 in (10 cm) longer than
other cables to the unit. This will maintain ground connection should the
cables be pulled off when the unit is extended beyond the length of the
cables.
To install ground terminal lug:
1. Cut a 6 AWG (4.11 mm) stranded grounding cable the appropriate length for the
iRU4438 iRRH installation.
2. trip away insulation from one end to expose 3/4 in (19 mm) of bare wire.
3. Crimp the dual-lug grounding terminal (supplied) to the cable using the special
purpose crimp tool specified in (or equivalent) as directed by tool manufacturer
instruction manual. Figure 5-3 shows assembled cable/lug assembly.
Figure 5-3 Grounding terminal lug assembled on grounding cable
5.2 Routing pre-assembled power/fronthaul Ethernet/grounding
cables
This procedures provides instructions for routing the pre-assembled 110/220 V ac
power cable, the CAT 5 Ethernet cable, and the grounding cable to the iRU4438 iRRH
mounting location before assembling the iRRH components.
To route cables:
1. Route the cables from the iRU4438 installation location to cable sources as shown
in Figure 5-4.
5-2

2. Secure and dress all cables according to Operator local practice.
5.3 Installing RF antennas on upper/lower omni-antenna brackets
This procedure describes installing up to four (4) omni-directional RF antennas on the
upper and lower antenna brackets.
To install antennas on brackets:
1. Remove the nut and flat washer from each of the antennas leaving the rubber Orings in place.
2. Install up to two (2) omni-antennas on the upper antenna bracket as shown in
Figure 5-5 using hardware removed from the antennas in step 1.
3. Tighten the antenna nuts 6-7.4 ft-lb (8-10 Nm) using a torque wrench.

5.4 Installing RF antenna cables
The RF antenna cables are shipped installed on the iRU4438 iRRH. If for any reason
the RF cables are removed, the following procedure provides instructions for routing
and connecting the cables. The RF antenna cables connect to the omni-directional
antennas. The upper RF antenna cables are 10.5 in (26.7 cm) in length. The lower RF
antenna cables are 26.5 in (67.3 cm) in length.
DANGER
RF antenna coaxial cables may be damaged if bent or curved to a radius
that is less than the recommended minimum bend radius of 0.6 in (1.52
cm). Always observe the recommended bend radius limit when routing
coaxial cables.
The RF coaxial cables are routed from the N-type connector at the base of each omnidirectional antenna to the corresponding QMA RF jack located on the front of the
iRRH. Antenna and connector designations are shown in Figure 3-5 and Figure 3-6,
respectively.
The four QMA RF jacks on the front of the iRU4438 iRRH are labeled ANT 1–4 (as
viewed from right to left) and as shown in Figure 3-5. The four omni-directional
antennas are designated OMNI 1–4 and are configured as shown in Figure 3-6. The
RF cable routing is shown in Figure 5-4.

NOTE
NOTE
Leave the dust cover on any unused antenna port.
The RF connections must be waterproofed using a self-fusing tape made
for that purpose. The application of the tape will vary by Operator, so
local practice will determine how the tape is applied.
To install RF cables:
1. Route one RF cable from ANT 1 to OMNI 1. Orient the cable with the N-type
connector end at the antenna and the QMA-type connector end at the RF jack on
the iRRH.

2. Connect the RF cable N-type connector to the OMNI 1 antenna and secure 15 in-lb
(1.7 Nm).
3. Connect the RF cable QMA-type connector to the ANT 1 RF connector on the front
of the iRRH by pushing on it until it snaps into place.
4. Repeat step 1 through step 3 for the remaining RF cables according to the RF
cable connection scheme provided in Table 3-3.
5. If required, waterproof the connections by wrapping each connector with selffusing tape according to Operator local practice.
5.5 Installing the iRU4438 iRRH mounting bracket

NOTE
NOTE
NOTE
The wall where the iRU4438 iRRH is to be mounted must be able to
support four times the weight of the unit. The unit can be mounted at a
deviation from vertical of ≤ 10°.
The mounting clamp is not used when mounting the iRU4438 iRRH to a
wall or other flat surface. In addition, the M12 bolts supplied in the
hardware kit are not used for wall-mount applications.
The Operator must provide two (2) M12 anchors, designed for outdoor
use, that are compatible with the type structure on which the iRRH is to
be installed.
To install mounting plate on a wall:
1. Determine the location where the mounting bracket is to be installed.
NOTE
The center-to-center distance for drilling holes to install the selected
anchor is 5.5 in (140 mm).
2. Using a tape measure and spirit level, mark where the anchor will be installed
using a center punch.
3. Drill the holes where the fastener will be installed on the wall using a drill bit sized
for the fastener.
4. Install the iRRH mounting bracket to the wall using the two (2) M12 anchor bolts
selected and supplied by the Operator, two (2) washers and two (2) lock washers
supplied with the mounting hardware.
5. Tighten the bolts as specified by the M12 anchor's manufacturer using a torque
wrench.
5.6 Hoisting the iRU4438 iRRH on elevated structures
Hoist line and tag line lift points are provided on the iRU4438 iRRH. These are the
ONLY recommended locations of attachment when hoisting and guiding the iRRH into
position on elevated structures. Carabiners should be used at both the hoist and tag
