The fuse is contained in the fuse holder on the front of the electrical box.
1
Remove the fuse holder cap.
• Turn the cap counterclockwise to remove it from the fuse
holder.
2
Check whether the fuse has blown.
How to check for a blown fuse.
• Visually check the wire inside the glass tube. If the wire is broken, the fuse has blown.
• Check the conductivity with a tester. If there is no conductivity, the fuse has blown.
3
Replace the fuse.
(1)
Remove the blown fuse from the cap holder.
(2)
Replace with a supplied fuse.
• Replacement fuse: ET1A (time-lag, low-breaking capacity; rating: 1A, 250 V AC)
4
Attach the cap to the fuse holder.
• Turn the cap clockwise, while pushing it in.
• Fuse replacement is only required if the external I/O terminals are used. For normal use without the
external I/O terminals, replacement of the fuse is not necessary.
• Replace the fuse if the plotter stops operating when an emergency stop function or other device is
connected to the external I/O terminals.
• To prevent electric shocks, turn off the main power switch and disconnect the power socket before
replacing the fuse.
