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.

CAUTION
When servicing any printed circuit board, be sure to wear an anti-static wristband to ensure
proper grounding. If not, static electricity built on the human body may cause damage to electric
parts mounted on the board.
