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 loca-
tion 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.
