Fuses

The DC input to the board is protected by fuses. Figure 9 shows the positions (a-
d) of the fuses. In each position there are two 12 A fuses mounted in parallel.

Isolation

The board is equipped with 0 Ohm resistors tying SHELF_GND and GND/DGND
together. If 2250 V isolation is desired the resistors R33-R35 have to be removed.
Figure 10 shows the positions of the resistors R33-R35
