To Remove a Module

Warning Hazardous Voltages: Hazardous voltages are present in this device as long as any of the power supplies are connected to the AC power.
ESD Susceptibility: Static discharge can cause serious damage to sensitive semiconductor devices. Avoid handling the switcher circuit boards in high static environments such as carpeted areas and when synthetic fiber clothing is worn. Touch the frame to dissipate static charge before removing boards from the frame and exercise proper grounding precautions when working on circuit boards.
  1. Lift up the control panel lid and turn off all power supplies in the control panel.
  2. Disconnect the power supplies from mains power.
  3. Identify the module or blank cover plate that you want to remove.
  4. If you are removing a module, you must disconnect the cables to the module.
    Figure 1. Module Cables
    1. Disconnect the 4-conductor Module Power Cable from the module.
      This cable delivers power to all of the modules in the row. When unplugging the cable, ensure that you do not accidentally unplug it from any neighbouring modules.
    2. Disconnect both the CAT5 Module Control Link Cables from the module.
      This cable delivers all of the command signal to and from the module, as well as other modules in the same row.
  5. Use a 1/4 inch hex driver to remove the four Retaining Nuts located at each corner of the module.
