Replacing the fuse
Applicable models:
A fuse (rating: 250 V, 15 A (T)) is inserted in the EUT
power supply line. When 1 600 VA or 15.7 A is
exceeded, the protection function is activated, and the EUT power supply line is shut off. As such,
normally, this fuse does not blow. However, should this fuse blow due to errors in wiring or aging, you can
replace it.
1
Remove the power cord from the AC LINE IN inlet on the rear panel.
2
Remove the fuse holder using a flat-blade screwdriver or the like.
3
Replace the blown fuse with an appropriate one.
4
Attach the fuse holder.
Risk of electric shock.
• Before replacing the fuse, remove the power cord from the AC LINE IN inlet for the
EUT power supply.
• Use a fuse compatible with the product in shape, rating, and characteristics. Using
a fuse with a different rating or shorting the fuse holder is dangerous.
