Installing the iRM4451
6-8 iRM4451 RRH Product Description and Installation Guide
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. There are two (2) M6 × 20 mm SEMS captiv
e screws on the top of the mounting
plate. See Figure 6-17. Start threading the M6 screws
into the mounting bracket
screws. Do NOT fully tighten.
4. Insert two (2) M4 × 20 mm SEMS screws into the screw holes on ei
ther side of the
mounting plate.
5. Tighten the M4 screws on the side 13.3 in
-lb (1.5 Nm) using a torque wrench.
6. Tighten the M6 screws to 9 in-lb
(1 Nm) using a torque wrench.
6.6 Connecting the grounding cable
This section provides the procedure for properly grounding the iRM4451 to an earth
grounding point. Verify that grounding cable/lug assembly is terminated at the other
end to a tested earth grounding point according to Operator local practice.
