TRT3x Introduction

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).
