1 Introduction The purpose of this Manual is to provide helpful instructions on how to use TRT3x instrument safely, properly and efficiently. The following instructions will help the user avoid unsafe situations, reduce maintenance costs and will ensure the reliability and durability of TRT3x instrument. TRT3x must be used in accordance with all existing safety requirements and regulations based on national/local standards for accident prevention and environmental protection. In addition, the relevant international standards are listed in paragraph 8.6 of the “Technical Data” section of this document. 1.1 Safety Instructions Safety is the responsibility of the user. Before operating TRT3x, please read the following safety instructions carefully. It is not recommended that TRT3x is used (or even turned on) without careful observation of the instructions listed in this Manual. TRT3x should only be operated by trained and authorized personnel. 1.1.1 Safety Terms and Symbols Terms in this Manual These terms may appear in the Manual: WARNING: Warning indicates that potential hazard may occur. CAUTION: Caution indicates that potential damage may occur to the instrument or to the test object connected to the instrument. Terms on the Device The following warning terms used in this document may appear on the device: WARNING: indicates that potential hazard may occur. CAUTION: indicates that potential damage may occur to the instrument or to the test object connected to the instrument. Symbols on the Device The following symbols may appear on the device: Refer to Protective Manual Earth Terminal 1.1.2 Terms of Use • TRT3x shall be used only if it is in good technical condition. Its use shall be in accordance with local safety and industrial regulations. Adequate precautions must be taken to avoid any risks related to high voltages associated with this equipment and nearby objects. • TRT3x shall be used only for the application purposes described in the ”Intended Use” section. The manufacturer and distributors are not liable for damage resulting from wrong usage. The user bears responsibility for not following the instructions defined in this document. • Do not remove the protective casing of TRT3x. • All service and maintenance work must be performed by qualified personnel only. TRT3x Introduction M-T03XNN-205-EN 4 1.1.3 Orderly Practices and Procedures • The Manual shall always be available on the site where TRT3x is used. • Before using TRT3x, all personnel (even personnel who only occasionally, or less frequently, work with TRT3x) assigned to operate TRT3x should read the operations Manual. • Do not make any modifications, extensions, or adaptations to TRT3x. • Use TRT3x only with the original accessories provided by the manufacturer. • Use TRT3x and its original accessories for the device’s intended use only. 1.1.4 Instrument Maintenance The device should be kept clean in order to prevent excessive cases of dust or other contaminants affecting its operation. It should be cleaned with water/isopropyl alcohol after any dirt/contaminants are noticed on its surfaces. 1.1.5 Operator Qualifications • Testing with TRT3x should only be carried out by authorized and qualified personnel. • Personnel receiving any training or instructions on TRT3x should remain under constant supervision of an experienced operator while working with the test set and the test object. 1.1.6 Safe Operating Procedures • Hazardous voltages of up to 400 V can occur inside TRT3x. Therefore, it is not permitted to remove the protective casing of TRT3x. • Hazardous voltages exist on the terminals of TRT3x when the “Red” LED is lit. Never assume connections are safe even if this LED is off. Switch off and unplug TRT3x before touching connections, particularly if a fault is suspected. • Before putting TRT3x into operation, check the test set for any visible damage. • Do not operate TRT3x under wet or moist conditions (condensation). • Do not operate TRT3x if explosive gas or vapors are present. • Only external devices that meet the requirements for SELV equipment according to EN 60950 or IEC 60950 should be connected to TRT3x through the serial interface. • Removing theTRT3x protective casing will void the warranty. Any work inside the instrument without prior authorization from DV Power will also void the warranty. • If TRT3x seems to be malfunctioning, please contact the DV Power Support Team (refer to the “Manufacturer Contact Information” section) after previously checking the “Error Messages” section. • Prior to connecting TRT3x, ensure that a transformer (object) to be tested is completely de-energized and isolated from both the line and the load. Every terminal should be checked and verified before connecting TRT3x. Ground connections may be left in place. • Do not use TRT3x without the extra protective ground cables supplied with TRT3x. It must never be operated in a non-grounded configuration as this may result in an electrical shock to the user or damage to TRT3x. Always establish this connection first before establishing any other connections and remove this connection as the very last one. • Wherever possible, the outer casing of the transformer under test should also be connected to a safety earth to prevent the risk of shock. Where this cannot be achieved, adequate precautions should be taken to prevent access to the transformer (e.g. barriers).
