M7/M7L/M7LT - Rev. 0.05 2-7

NOTE: The internal AC or DC BUC power supplies in the M7LT can be changed in the field by a

qualified operator. Figure 2-6 shows the location of the BUC power supply in the AC input

power unit and Figure 2-7 shows the location of the BUC power supply in the DC input unit.

Instructions on how to acquire and install a different BUC power supply can be found in an

Application Note.
