Disconnect main power when making connections to the SI-6 or KBMMTM. Description of Changes Tach-generator feedback formula is corrected to include the subtraction symbol which was missing. Figure 12B is corrected to show the tach-generator connection to Terminals "I1" and "F-" on SI-6. Application Note: Be sure to connect the gray wire to Terminal "I1" on the SI-6 and to Terminal "T" on the KBMMTM. Do not connect the tach-generator to Terminals "COM" and "I1". IV.
