2. At the back of the TPU2000 or the TPU2000R chassis, in the left-hand lower section of the unit, a label shall
appear indicating the serial number and model number of the unit. It should match the data presented in the
ECP, WinECP or Front Panel Interface (FPI) Menus. If it does not, please contact the factory.
3. As a final check, if the TPU2000 or TPU2000R can be powered-down or if protection can be interrupted,
loosen the front panel screws at the front of the unit. Remove the product component drawer from the
chassis. Face the front panel interface, and rotate the board so that the semiconductor components are
directly visible. On the backside of the metal panel supporting the Front Panel Interface, a label shall be
available indicating the serial number and model number. These numbers should match those obtained in
steps 1 and 2. If they do not, please contact the factory.
