9. FUSE REPLACEMENT
If external fuses blow, (or breakers trip), then there is a short or overload in the DC
wiring. Find and fix the problem before replacing the fuses (or resetting the breaker).
After fuse replacement, reconnect the inverter.
This power inverter is equipped with multiple internal fuses. Normally, these fuses
will not blow unless there is a serious problem inside the unit. Internal fuses are
replaceable, however, only electronically knowledgeable people should attempt fuse
replacement. If the unit is damaged during fuse replacement, the warranty may be
voided. Vector recommends contacting Technical Support for guidance. Based on
experience, it is best to return the unit to Vector for repair. Vector Technical Support
can be reached by calling toll free 866-584-5504. You may also contact us by visit-
