Replacement fuses

Fuse, 8 A/250 V, quick

1) To achieve maximum performance capability, 

distribute the high-current load between the two 
groups.

2) To reset a deactivated output,
 

first set the output signal to 0 and then to 1.

If output signal 1 is written to a deactivated
output and the short circuit remains, additional 
interrupts are generated (provided the diagnostic 
interrupt parameter was set).
