15A Mains fuse for 220-240 VCA. The device is set
up with a 15A fuse to operate on a main voltage of
220-240 VAC. To work with other main voltages
(100-127 VAC), replace the 15A fuse with the 30A
fuse supplied with the device.
ATTENTION: MAKE SURE TO DISCONNECT THE
POWER CORD FROM THE AC INLET BEFORE
REPLACING A FUSE.
