TRT33A Safety Instructions
• If TRT33A is opened by the customer, all guarantees are invalidated.
• If TRT33A seems to be functioning improperly, please contact the IBEKO POWER AB (refer to
section
”Manufacturer Contact Information”), after first checking the section Error Messages.
• Before connecting the TRT33A ensure that the transformer to be tested is completely de-energized
and isolated from both line and load. Every terminal should be checked and verified before
connection of the TRT33A. Ground connections may be left in place.
• Do not use TRT33A without the extra protective ground cables for the TRT33A. It must never be
operated in a non-grounded configuration as this may result in electrical shock to the user or damage
to the TRT33A. Always establish this connection as the first one before you do any other
connections, and separate this connection as the very last one.
• Where 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, such as barriers.
• Never exchange connections to the HV and LV sides of the transformer. The "H" connections must
always be connected to the High Voltage side of the transformer. The "X" connections must always
be connected to the Low Voltage side of the transformer. Interchanging any or all of the connections
may result in damage to the transformer or the TRT33A and represents a significant safety hazard
for personnel.

Power Supply
• Supply TRT33A only from a power outlet that is equipped with protective ground.
• Instead of supplying TRT33A from phase – neutral (L1-N, A-N, H1-H0), it may also be supplied from
phase to phase (e.g., L1-L2; A-B; H1-H2). However, the voltage must not exceed 240 V AC, please
refer to the section “Technical Data”.
