R1.2, March 2018

8.0.2 Input Fuses

The –48 V input circuits are protected by fuses, one in the supply and in the return path.

Figure 12: Input fuses

8.0.3 Voltage and Fuse Monitoring

To detect a missing supply voltage as well as a blown fuse the ADT7490 and PCA9555 provide
voltage monitoring and control functions.

The fuses are not user-serviceable.
