(AUXILIARY) LABELS
The labels shown in Figures 3-39 and 3-40 are used to identify the leads and connection point
for -48 volt power to the Z1A Emergency Transfer Unit and the control carrier AUXILIARY
connector outputs. The top half of the labels are used for the Z1A Emergency Transfer Unit
and the bottom half of the labels are used for the control carrier AUXILIARY connector
outputs. The control carrier AUXILIARY connector outputs are the same as described for
the auxiliary circuit and control carrier AUXILIARY outputs labels.
