SAFETY SUMMARY
ix
DO NOT BYPASS INTERLOCKS
Do not bypass any interlocks unnecessarily. If it is necessary to employ an interlock bypass for equipment
servicing, use extreme care not to come in contact with hazardous voltages.
USE CARE HANDLING HEAVY EQUIPMENT
Never attempt to lift large assemblies or equipment without knowing their weight. Use enough personnel or a
mechanical lifting device to properly handle the item without causing personal injury.
HEED WARNINGS AND CAUTIONS
Specific warnings and cautions are provided to ensure the safety and protection of personnel and equipment.
Be familiar with and strictly follow all warnings and cautions on the equipment and in technical manuals.
PROTECTIVE EYEWEAR
All personnel must wear protective eyewear when servicing or maintaining equipment. Protective eyewear
must be worn at all times when using tools.
4. PROTECTION OF STATIC-SENSITIVE DEVICES
Diode input-protection is provided on all CMOS devices. This protection is designed to guard against adverse
electrical conditions such as electrostatic discharge. Although most static-sensitive devices contain protective
circuitry, several precautionary steps should be taken to avoid the application of potentially damaging
voltages to the inputs of the device.
To protect static-sensitive devices from damage, the following precautions should be observed.
a. Keep all static-sensitive devices in their protective packaging until needed. This packaging is
conductive and should provide adequate protection for the device. Storing or transporting these
devices in conventional plastic containers could be destructive to the device.
b. Disconnect power prior to insertion or extraction of these devices. This also applies to PWBs
containing such devices.
c. Double check test equipment voltages and polarities prior to conducting any tests.
d. Avoid contact with the leads of the device. The component should always be handled carefully by
the ends or side opposite the leads.
e. Avoid contact between PWB circuits or component leads and synthetic clothing.
f. Use only soldering irons and tools that are properly grounded. Ungrounded soldering tips or tools
can destroy these devices. SOLDERING GUNS MUST NEVER BE USED.
