Installing the iRU4438 iRRHiRU4438 iRRH Product Descripton and Installation Guide 5-15 Installing the iRU4438 iRRHThis 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 cables5.1.1 Verify Operator supplied 110/220 V ac power cableThe 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 cableThe 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 hand-tightened to complete the weatherproof seal.Figure 5-2 CAT-5 Ethernet cable gland assembly5.1.3 Verify Operator supplied grounding cableThe 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.
Installing the iRU4438 iRRH5-2 iRU4438 iRRH Product Descripton and Installation GuideNOTEThe 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 cable5.2 Routing pre-assembled power/fronthaul Ethernet/grounding cablesThis 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.

Secure and dress all cables according to Operator local practice.5.3 Installing RF antennas on upper/lower omni-antenna bracketsThis 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 O-rings 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.

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. DANGERRF 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 omni-directional 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.
