Installing the iRU4438 iRRH
5-2 iRU4438 iRRH Product Descripton and Installation Guide
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 appr
opriate 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 cri
mp tool specified in (or equivalent) as directed by tool manufacturer
instruction manual. Figure 5-3 shows assembled cable/lug assembly.

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 locat
ion to cable sources as shown
in Figure 5-4.
