1 Precaution Statements1-2 Servicing PrecautionsWARNING: First read the-Safety Precautions-section of this manual. If some unforeseen circumstance creates a conflictbetween the servicing and safety precautions, always follow the safety precautions.WARNING: An electrolytic capacitor installed with the wrong polarity might explode.1. Servicing precautions are printed on the cabinet.Follow them.2. Always unplug the units AC power cord from the ACpower source before attempting to:(a) Remove or reinstall any component or assembly(b) Disconnect an electrical plug or connector(c) Connect a test component in parallel with anelectrolytic capacitor3. Some components are raised above the printed circuitboard for safety. An insulation tube or tape issometimes used. The internal wiring is sometimesclamped to prevent contact with thermally hotcomponents. Reinstall all such elements to theiroriginal position.4. After servicing, always check that the screws,components and wiring have been correctlyreinstalled. Make sure that the portion around theserviced part has not been damaged.5. Check the insulation between the blades of the ACplug and accessible conductive parts(examples : metal panels and input terminals).6. Insulation Checking Procedure:Disconnect the power cord from the AC source andturn the power switch ON. Connect an insulationresistance meter (500V) to the blades of AC plug.The insulation resistance between each blade of theAC plug and accessible conductive parts (see above)should be greater than 1 megohm.7. Never defeat any of the B+ voltage interlocks.Do not apply AC power to the unit (or any of itsassemblies) unless all solid-state heat sinks arecorrectly installed.8. Always connect an instrument’s ground lead to theinstrument chassis ground before connecting thepositive lead ; always remove the instrument’s groundlead last.1-3 Precautions for Electrostatic Sensitive Devices (ESDs)1. Some semiconductor (solid state) devices are easilydamaged by static electricity. Such components arecalled Electrostatic Sensitive Devices (ESDs);examples include integrated circuits and some fieldeffecttransistors. The following techniques will reducethe occurrence of component damage caused by staticelectricity.2. Immediately before handling any semiconductorcomponents or assemblies, drain the electrostaticcharge from your body by touching a known earthground. Alternatively, wear a discharging wrist-strapdevice. (Be sure to remove it prior to applying power- this is an electric shock precaution.)3. After removing an ESD-equipped assembly, place iton a conductive surface such as aluminum foil toprevent accumulation of electrostatic charge.4. Do not use freon-propelled chemicals. These cangenerate electrical charges that damage ESDs.5. Use only a grounded-tip soldering iron whensoldering or unsoldering ESDs.6. Use only an anti-static solder removal device. Manysolder removal devices are not rated as anti-static;these can accumulate sufficient electrical charge todamage ESDs.7. Do not remove a replacement ESD from its protectivepackage until you are ready to install it. Mostreplacement ESDs are packaged with leads that areelectrically shorted together by conductive foam,aluminum foil or other conductive materials.8. Immediately before removing the protective materialfrom the leads of a replacement ESD, touch theprotective material to the chassis or circuit assemblyinto which the device will be installed.9. Minimize body motions when handling unpackagedreplacement ESDs. Motions such as brushing clothestogether, or lifting a foot from a carpeted floor cangenerate enough static electricity to damage an ESD.1-2 SAM4S ER-430 SERIES
