Installing the iRM4451 6 Installing the iRM4451 This section provides the procedure for installing the iRM4451 RRH 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. 6.1 Assembling cables The operator will need to order, pre-assemble, and pre-install various cables to the iRM4451. 6.1.
Installing the iRM4451 To install ground terminal lug: 1. Cut a 6 AWG (4.11 mm) stranded grounding cable the appropriate length for the iRM4451 installation. 2. Strip 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 specialpurpose crimp tool specified in Required tools on page 4-1 (or equivalent) as directed by tool manufacturer instruction manual. Figure 6-12 shows an assembled cable/lug assembly.
Installing the iRM4451 Figure 6-13 iRM4451 cable routing 2. Secure and dress all cables according to Operator local practice. 6.3 Installing the iRM4451 mounting bracket This section provides the procedure for installing the iRM4451 on a mast/pole pipe, Vangle or H-angle, or mounting on a wall. The iRM4451 can be installed on a pole/mast structure having the following dimensions using the supplied mounting bracket assembly: Pole/mast:2.36-4.49 in (60-114 mm) U-frame:1.97-3.94 in (50-100 mm) V-frame:1.
Installing the iRM4451 NOTE The iRM4451 is shipped from the factory with the mounting plate preinstalled on the chassis as shown in Figure 6-14. Figure 6-14 iRM4451 mounting plate 6.3.1 Mounting on a pole/mast The following procedure provided instructions for mounting the iRM4451 on a pole/ mast using the supplied mounting bracket assembly. To install mounting plate on a pole or mast: 1. Install the mounting bracket and mounting clamp onto the pole/mast with mounting hardware as shown in Figure 6-15.
Installing the iRM4451 Figure 6-15 Installing mounting bracket on a pole NOTE IMPORTANT! Maintain the parallel orientation of the clamp and bracket while tightening the nuts. This will require alternating tightening the nuts on each screw stud until the final torque is achieved. 6.3.2 Mounting on a wall The following procedure provides instructions for mounting the iRM4451 to a wall or other flat, vertical surface.
Installing the iRM4451 NOTE NOTE The mounting clamp is not used when mounting the iRM4451 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 four (4) M12 anchors, designed for outdoor use, that are compatible with the type structure on which the iRM4451 is to be installed. To install mounting plate on a wall: 1. Determine the location where the mounting bracket is to be installed.
Installing the iRM4451 NOTE WARNING Because of the differences Operator is responsible for determining an industry-approved, safe method of hoisting the iRM4451 into position onto elevated structures. Be sure to follow all established Operator local practice and safety precautions when hoisting the equipment on elevated structures. Figure 6-16 Hoist line carabiner attachment point 6.
Installing the iRM4451 To install iRM4451 on the mounting bracket: 1. Hang the iRM4451 chassis on the mounting bracket by aligning the mounting plate tabs on the rear of the chassis to the mounting bracket slots (see Figure 6-17). Figure 6-17 Aligning mounting plate tabs to mounting bracket 2. Lower iRM4451 onto the mounting bracket and align the tapped screw hole on top of the mounting plate with the tapped screw hole on the mounting bracket. 3.
Installing the iRM4451 To connect grounding cable: 1. Fasten the dual-hole grounding lug and cable assembly to the iRM4451 chassis grounding posts using two (2) M5-0.8 screws and washers (supplied by Operator). See Figure 6-18. Figure 6-18 Connecting the grounding cable 2. Tighten the bolts to 2.4 ft-lb (3.2 Nm) using a torque screwdriver. 3. 4. 5. 6. 6.1 Connecting the RET cables This section provides the procedure for connecting the RET cable to the RET connector socket. To connect RET cable: 1.
Installing the iRM4451 To connect GigE optical fronthaul cables: 1. Remove the captive dust cover of the FH1 fiber optic cable entry port by turning counterclockwise. 2. Remove the captive dust cover from the Huber + Suhner Q-XCO fiber optic cable connector by simultaneously squeezing the lock latches on either side of the quick-lock mating connector and turning the dust cover counterclockwise just past where the arrows come into alignment and pull, gently but firmly. 3.
Installing the iRM4451 NOTE It is recommended that the –48 V dc power connection 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. 3. Waterproof the connection by wrapping the connector with self-fusing tape (refer to Required tools on page 4-1) according to Operator local practice. 6.
