Up to eight DBK84 options can be powered from the DB37 P1 connector.
For applications with 9 to 15 DBK84 options, a DBK32A must be added to the system.
The WBK41 includes a Power Terminal Block on the front panel. When used, it draws
from the total power available to P1.
Fuses:
Input Power Fuse (F201): 4A MINI ATO, user replaceable; refer to page 23 for details.
5V Power Output Fuse (F1): 2.5A resettable; not user replaceable.
