mounting plate tabs on the rear of the chassis to the mounting bracket slots (see
Figure 6-6).
Figure 6-6 Aligning mounting plate tabs to mounting bracket
2. Lower iRM4451nn00-2 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 captive screws on the top of the mounting
plate. See
Figure 6-6. 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 either 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 iRM4451nn00-2 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 local practice.
