NOTE !
Verify for correct fuse rating “F1 - F2
- F3 - F4” on dependence of the
power supply input voltage,
according to the table below.
In case of replacement the same
type and the same rating must be
used.
The replacement of fuses must be
performed by QUALIFIED SERVICE
PERSONNEL only.
For 208 VAC 0.75 A Fuse type Class CC – Time Delay – 13/32” x 1 1/2” – 600 VAC
For 400 VAC 0.3 A Fuse type Class CC – Time Delay – 13/32” x 1 1/2” – 600 VAC
For 480 VAC 0.3 A Fuse type Class CC – Time Delay – 13/32” x 1 1/2” – 600 VAC
