The following information is Included in this section: • Safety Precautions • Electrical Code Requirements • Switches • Protective Barriers to Operators • Internal Hazardous Power Connections • Power Control and Distribution • Power Supplies • Internal Protective Barriers • Laser Energy • Heavy Weight Removal Instructions • Special Hazard Warnings • External Mechanical Hazards • Electrostatic Discharge Damage • Materials Handling • Safe Work Practices • Electrical Hazards • Hardware Torque Requirements • Safe Equipment Practices • Environmental Conditions • Grounding • Summary Page 1 of 8 Rev. 0736 Ultra System Overview General Safety Information Safety Precautions Numerous features incorporated in the test system provide a minimum of safety, such as: • Grounded or nonconductive system covers that require tools for removal • Safety warnings and information labels on the system where appropriate • Detailed installation, checkout and service documentation Electrical Code Requirements All inputs to the main facility AC service disconnect must meet local electrical code requirements. The cables, circuit breakers, contactors and transformers selected have defined qualities that meet the electrical code requirements as understood by Teradyne, Inc., for the countries where the product may be sold. These parts should be replaced only with Teradyne approved FRUs or equivalents. All AC power connections must be torqued to their defined specifications to avoid localized heating and possible ignition, or damage to the screw connections, whenever screw type connections are used. Switches The test system has many safety switches. Never attempt to defeat a switch or interlock in any way. See the Switches and Protective Barriers section of this documentation for additional information. The switches include: • Main Power • Test System Power • Emergency Off (EMO) Protective Barriers to Operators There are safety interlocks and warning labels to impede operator access to service or electrical hazard areas of the test system and test head electronics. See the Switches and Protective Barriers section of this documentation for additional information. Internal Hazardous Power Connections The internal power connections of the test system present many safety hazards. Detailed safety hazard information can be found in each safety section and specific test system section of this documentation. All internal areas of the system must be accessed and serviced only by trained and qualified personnel. Page 2 of 8 Rev. 0736 Ultra System Overview General Safety Information Power Control and Distribution All power connections inside the power distribution, support cabinet or power supply units, as well as distribution between these assemblies, are extremely hazardous and potentially lethal. Trained and qualified personnel must exercise extra caution and care when servicing these areas. Internal plug-connected AC power is also hazardous and should be handled with the reasonable care due any AC service. Power Supplies Most power supply terminals and backplane buses in the test system present a high-voltage or high-current power hazard. Hazardous voltages are present on power supply connections and power buses, therefore extra caution must be taken when servicing these areas. Because of these high-power hazards, jewelry, such as rings, watches and necklaces, and other conductive ornaments should not be worn when servicing these areas. Caution should also be used with conductive tools. Current levels are sufficient to cause severe sparking or welding if conductive parts bridge different potentials. Internal Protective Barriers The inner doors provide protective barriers to internal hazards for unauthorized personnel. The following internal protective measures have been implemented: • Warning labels and strategic design and layout provide the primary protection to service personnel. • Special hazard areas may have additional mechanical barriers, such as an AC mains transformer and power supplies. • All conductive framing has been electrically connected to a protective ground by green ground wires with a yellow stripe, or by electrically conductive joints. • Interlock switches are present in various locations throughout the system. These switches remove power to certain areas when doors are opened or components are moved. Never defeat an interlock switch. • EMO switches are present in various locations of the system. These switches remove power to the test system when they are activated.

Use of controls or performing adjustment or maintenance procedures other than those specified in this documentation may result in hazardous radiation exposure. There are as many as 4 lasers present in the UltraFLEX test system. Two are always present - the laser for the databus card and the matching laser on the support board. Two additional lasers are added when the DSP option is installed. One in the DSP computer and one on the XGEM module. Laser Specifications 1.

Special Hazard Warnings Information symbols and electrical hazard or other appropriate warnings have been placed close to hazards to alert service personnel to potential hazards. See the Safety Terms, Labels and Symbols section of this documentation for additional information. External Mechanical Hazards Computer displays and some optional external assemblies are movable. Caution should be used when in proximity to these assemblies to prevent bodily injury and damage to the equipment. Electrostatic Discharge Damage The test system contains semiconductors that, by the nature of their material (such as MOS) or design (such as LSI, VLSI, FET), are susceptible to damage from electrostatic discharge (ESD). ESD control measures are therefore necessary and offer protection by degree, with static-prevention techniques providing the most protection. The following control measures are strongly recommended for consideration and implementation. • Wear a tested-grounded wrist strap. Refer to the figure ESD Equipment in the ESD Damage Prevention and Control Measure section of this documentation for additional information. • Use static-conductive floor mats
