2.1REMOVING THE PROFILE CONTROLLER FROM ITS HOUSING

CAUTION: Before removing the instrument from its housing, ensure that all power has been removed from the rear terminals.

To withdraw the instrument from its housing, simply grip the side edges of the front panel (there is a finger grip on each edge) and pull the instrument forwards. This will release the instrument from its rear connectors in the housing and will give access to the instrument PCBs. Take note of the orientation of the instrument for subsequent replacement into the housing.The positions of the PCBs in the instrument are shown in Figure 2-1.
