Page 203: Section 4 - Maintenance
Maintenance Introduction This section provides maintenance and safety information for servicing the Model 3000 Signal Processor Frame, Control Panel, and Power Supplies. Refer to the Diagnostics and Troubleshooting section for procedures to be used to isolate and resolve specific problems. Torx-head screws are used in the manufacture of many mechanical NOTE: components on this equipment.
Page 204: Removing Circuit Modules
Section 4 – Maintenance WARNING Unless speciﬁcally directed to do otherwise by a maintenance procedure, turn power off before removing or repairing any circuit module or assembly in this system. Before working on any power supply assembly, turn off the power and disconnect the power cord from the AC power source.
Page 205: Repairing Circuit Modules
Repairing Circuit Modules CAUTION If a circuit module in the Signal Processor frame is removed or reinstalled while the power is on, it is unlikely that permanent damage will occur to the module or system. Microprocessor messages, however, may become scrambled. This may result in system errors and improper operation.
Page 206: Power Supply Configurations
Section 4 – Maintenance WARNING Remove all rings and other jewelry when you are working on equipment that is powered up. Hazardous currents are present in the power supplies, on the backplane, and on circuit modules. Failure to follow this precaution could result in severe shock and other injury.
