Appendix ● Module Installation The module installation procedure is the reverse of the removal procedure described above. Rear Panel Input Units First pass the wiring through the opening in the rear panel and pull it through to the open module area. Then attach the rear-panel unit with two screws. Top-panel Modules When an input module is being installed it is first necessary to connect the wiring from the corresponding rear-panel input unit to the connectors on the module and secure the wire bundle in the wiring harness. When inserting the module into the console make sure that the connectors on the bottom of the module are aligned with the corresponding connectors on console frame. Input modules have two connectors (see the illustration below), while master modules have three. Guide pins are provided to make alignment easy - as long as the guide pins are properly inserted into the corresponding holes on the bottom of the module frame alignment should be almost automatic. Insert the module firmly until its panel is flush with the console top, but avoid using excessive force. Input Transformer Installation The PM5000 input modules feature electronically balanced inputs that do not normally require any additional isolation. If you would rather have conventional transformer-isolated balanced inputs, optional ITR5000 input transformers can be installed. NOTE The input impedance will change when the transformers are installed: electronically balanced input impedance = 3 kΩ, transformer input impedance = 1 kΩ. The number and location of input transformers is different for mono and stereo input modules. The installation procedure is outlined below. ● Transformer Installation On Input modules 1 Turn the console's power supply OFF. 2 Remove the mono or stereo console on which the transformer(s) is to be installed as per the moduleremoval instructions above. 3 Attach the transformer to the mounting bracket supplied with the ITR5000 transformer kit with the nut as shown in the illustration. Make sure that the transformer leads are positioned in relation to the mounting bracket as shown in the illustration (the transformer leads must not be clamped between the transformer and mounting bracket). Do not clamp the transformer leads when mounting Guide pins Finally, secure the module with the two screws. NOTE When a module and/or rear-panel unit has been sent out for repair and the module slot is likely to be empty for a while, it is a good idea to install the blank module panels (BLM5000) to prevent objects from falling into the console and potentially causing damage. The BLM5000 blank module option includes blank panels for both the top-panel and rear-panel. 86 Transformer Transformer mounting bracket 4 Attach the transformer to the bottom stay of the module. Align the screw holes in the transformer mounting bracket with the screw holes just in front of (toward the fader end of the module) the square hole through provided for the transformer leads as shown in the illustration below, and secure with the two small M3 screws. On mono modules the transformer should face toward the front (fader) end of the module, and on stereo modules the second transformer should be mounted on the other side of the square lead hole, facing in the other direction so that the lead hole is not obstructed.
