Fluke Corporation OPERATOR SAFETY SUMMARY WARNING HIGH VOLTAGE is used in the operation of this equipment LETHAL VOLTAGE may be present on the terminals, observe all safety precautions! To avoid electrical shock hazard, the operator should not electrically contact the output hi or sense hi bind- ing posts. During operation, lethal voltages of up to 1100V ac or dc may be present on these terminals. Whenever the nature of the operation permits, keep one hand away from equipment to reduce the hazard of current flowing thought vital organs of the body. Terms in this Manual This instrument has been designed and tested in accordance with IEC Publication 348, Safety Requirements for Electronic Measuring Apparatus. This manual contains information and warnings which have to be followed by the user to ensure safe operation and to retain the instrument in safe condition. Warning statements identify conditions or practices that could result in personal injury or loss of life. Caution statements identify conditions or practices that could result in damage to the equipment or other property. Symbols Marked on Equipment DANGER High Voltage Protective ground (earth) terminal Attention refer to the manual. This symbol indicates that information about the usage of a feature is contained in the manual. Power Source The 5725A is intended to operate from a power source that will not apply more than 264V ac rms between the supply con- ductors or between either supply conductor and ground. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation. Use the Proper Fuse To avoid fire hazard, use only the fuse specified on the line voltage selection switch label, and which is identical in type volt- age rating, and current rating. Grounding the 5725A The 5725A is Safety Class I (grounded enclosure) instruments as defined in IEC 348. The enclosure is grounded through the grounding conductor of the power cord. To avoid electrical shock, plug the power cord into a properly wired earth grounded receptacle before connecting anything to any of the 5725A or 5700A terminals. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation. Use the Proper Power Cord Use only the power cord and connector appropriate for proper operation of a 5725A in your country. Use only a power cord that is in good condition. Refer cord and connector changes to qualified service personnel. Do Not Operate in Explosive Atmospheres To avoid explosion, do not operate the 5725A in an atmosphere of explosive gas. Do Not Remove Cover To avoid personal injury or death, do not remove the 5725A cover. Do not operate the 5725A without the cover properly in- stalled. There are no user-serviceable parts inside the 5725A, so there is no need for the operator to ever remove the cover. Do Not Attempt to Operate if Protection May be Impaired If the 5725A appears damaged or operates abnormally, protection may be impaired. Do not attempt to operate it. When is doubt, have the instrument serviced. SERVICING SAFETY SUMMARY FOR QUALIFIED SERVICE PERSONNEL ONLY Also refer to the preceding Operator Safety Summary Do Not Service Alone Do not perform internal service or adjustment of this product unless another person capable of rendering first aid and resuscitation is present. Use Care When Servicing With Power On Dangerous voltage exist at many points inside this product. To avoid personal injury, do not touch exposed connec- tions and components while power is on. Whenever the nature of the operation permits, keep one hand away from equipment to reduce the hazard of current flowing through vital organs of the body. Do not wear a grounded wrist strap while working on this product. A grounded wrist strap increase the risk of current flowing through the body. Disconnect power before removing protective panels, soldering, or replacing components. High voltage may still be present even after disconnecting power. FIRST AID FOR ELECTRIC SHOCK Free the Victim From the Live Conductor Shut off high voltage at once and ground the circuit. If high voltage cannot be turned off quickly, ground the circuit. If the circuit cannot be broken or grounded, use a board, dry clothing, or other nonconductor to free the victim. Get Help! Yell for help. Call an emergency number. Request medical assistance. Never Accept Ordinary and General Tests for Death Symptoms of electric shock may include unconsciousness, failure to breathe, absence of pulse, pallor, and stiffness, and well as severe burns. Treat the Victim If the victim is not breathing, begin CPR or mouth-to-mouth resuscitation if you are certified. i Table of Contents Title Page Introduction . 1 Contacting Fluke . 2 Where to Go From Here . 2 How to Use the Manuals . 4 5725A Getting Started Manual . 4 5725A Instruction Manual . 4 5700A/5720A Series II Manual Set . 4 5700A/5720A Series II Operator Manual . 4 5700A/5720A Series II Operator Reference Guide . 5 5700A/5720A Series II Remote Programming Reference Guide . 5 5700A/5720A Series II Service Manual . 5 General Specifications . 6 Unpacking and Inspection . 8 Service Information . 11 Placement and Rack Mounting. 11 Cooling Considerations . 12 Connecting to the 5700A Calibrator . 12 5725A Getting Started ii Selecting Line Voltage . 14 Accessing the Fuse. 16 Connecting to Line Power . 18 Front-Panel Features . 18 Rear-Panel Features. 22 Turning on the 5725A Amplifier . 25 Warm Up . 25 iii List of Tables Table Title Page 1.
