Generally, the screws and nuts have been installed on the
four corners of the purchased RTU module, as shown in
Figure 4-36. If no screw or nut is installed on the four
corners of the purchased RTU module, then you should first
install the screws and nuts, and then install the RTU on the
SMUB.

Before installing the SMUB, you should first install the uplink interface module and the RTU (optional).
To install the SMUB, take the following steps:
Step 1 Cut off the power supply before the installation.
Step 2 Make sure that 3P@C 4450E is well grounded and the operator
wears an antistatic wrist strap.
Step 3 Remove the dummy panel installed in the slot of the SMUB by
removing the screws.
Step 4 Take out the SMUB, align it with the slot, press the two puller
adapters outward with both hands, and push the SMUB along the
guide rail into the slot with even force till the SMUB touches the
connection socket on the backplane.
Step 5 Press the two puller adapters of the SMUB inward with both
hands to plug the SMUB into the connection socket on the
backplane. Now the two puller adapters are reset automatically.
Tighten the two screws on the puller adapters to fix the SMUB.
