The M-2299 is an adapter panel which, when combined with the M-2001 Series Digital Tapchanger Control, provides convenient direct replacement of Toshiba TB-R800 regulators. The M-2299 mounts into the control cabinet using the same two hinge pins which must be saved from the original regulator. Interface External connections are made via a wiring harness that connects from a fifteen-position terminal block to the ”BT” terminal block on the existing control cabinet. An additional terminal block
