Completing the Installation
ATTACHING THE
CONTROL
COVERS
After wiring and testing the system, install the front and
top cover on the control unit. (Refer to Figure 2-27.) A
set of covers should be installed on both the basic carrier
and the expansion carrier. Make sure that there is a
module in the rightmost slot of each carrier so that the
covers are properly supported. If no functional module
occupies the rightmost slot of a carrier, install the empty
module that came with the system. Refer to Figures 2-28
and 2-29 as a guide when attching the covers to the
control unit.
