EM 220 1-1 Safety Precautions 1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields. 2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices including: nonmetallic control knobs and compartment covers. 3. Make sure that there are no cabinet openings through which people – particularly children – might insert fingers and contact dangerous voltages.
EM 220 1-2 Servicing Precaution WARNING 1: First read the Safety Precaution section of this manual. If some unforeseen circumstance creates a conflict between the servicing and safety precautions, always follow the safety precaution. WARNING 2: An electrolytic capacitor installed with the wrong polarity might explode. 1.
EM 220 1-3 Precaution for Electrostatically Sensitive Devices (ESDs) 1. Some semiconductor (solid state) devices are easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits and some fieldeffect transistors. The following techniques will reduce the occurrence of component damaged caused by static electricity. 2.

EM 220 7. Troubleshooting Every undesired outcome can be investigated with fault tree analysis which is one of RCA (Root Cause Analysis). Fault tree analysis is a graphical representation of the major faults or critical failures associated with a product, the causes for the faults, and potential countermeasures. This way user can identify possible causes easily.
