Housing

After you complete system acceptance testing and if you are confident that the system is completely installed, you can install the control unit’s housing.

NOTE:

Beginning with Release 2.1 or later, the control unit covers are identical to those on the MERLIN II Communications System. If you need to install control unit covers on a system prior to Release 2.1, see Chapter 9, “Upgrading the System.”

Installing the Top Cover

To install the top cover, see Figure 7–2 and follow these steps:

! Be sure the cords have been pressed through the wire managers at the base of the modules.

! Hold the top cover with the hooks facing you.

! Engage the tabs at the rear of the top cover with the carrier.

! Lower the top cover so the legs lock into the vents on the module.
