2.1 REMOVING THE CONTROLLER FROM ITS HOUSING
CAUTION:
Before removing the Controller from its housing, ensure that all
power has been removed from the rear terminals.
To withdraw the Controller from its housing, simply grip the side edges of the front
panel (there is a finger grip on each edge) and pull the Controller forwards. This
will release the Controller from its rear connectors in the housing and will give
access to the Controller PCBs. Take note of the orientation of the Controller for
subsequent replacement into the housing.The positions of the PCBs in the
Controller are shown in Figure 2-1.
