How to Check Fuse
For no-fuse breaker (NFB)
The no-fuse breakers (NFB1-NFB2) are to be shorted (N) at factory prior to shipment and
must be so at installation. However, since they may unexpectedly turn OFF due to vibration
during transit, press all the no-fuse breaker buttons two or three times to ensure that they
are depressed to ON.

For directly-mounted fuse
With board version M or later, the no-fuse breaker (NFB) is replaced with the fuse.
