6.1 Removing and Installing A Module Figure 6-1. Removal of PM4000 Module 1. Turn the Power OFF first, before removing or installing a module. 2. Loosen the screws at the top and bottom of the rear panel input/output strip corresponding to the module being removed (except Master section modules). These screws are not retained so be sure to grasp them and set them aside for reinstallation of the module. [6-1A] 3. Loosen the retaining screws at the top and bottom of the module. These screws are retained in the module. [6-1B] 4. Lift up on the module's retaining screws (or you may also want to pull up gently on a control knob), and you will feel the two module connectors that join the connectors on the bottom of the console release. Then carefully lift the module out of the console. [6-1C] 5. Installation of a module should be done by reversing the order of this procedure. Work slowly to make sure that edge connectors mate properly. NOTE: If you are moving a module to a different location in the mainframe, one which had housed no module or a different type of module, then you will have to also move the rear connector panel. Monaural and Stereo input modules may be placed anywhere in the frame, and you can exchange them freely (so long as you use the correct input/output connector panel on the rear). However, there should be no more than a total of 64 input channels per mainframe. Page 6-2
