Fuse Replacement

WARNING:

BEFORE

REPLACING

THE FUSE,

DISCONNECT ALL

POWER SOURCES

AND TURN OFF

ALL LOADS.

NOTE: If the system also contains a DC disconnect, switch it to OFF before replacing the fuse.

NOTE: Fuses are NOT covered under the limited warranty.

Before replacing the fuse, determine and correct the cause of the overcurrent condition.

1.Use a hex socket and remove the two nuts (and split washers) securing the fuse. Note the hardware installed and the order of how it is stacked. This is important to prevent excess heat which can cause the fuse to open again.

2.Remove the open fuse and replace it with a known good one.

3.Reinstall the hardware as it was originally stacked on the fuse.

4.Tighten the hex nuts securing the fuse to 10-15 ft/lbs.

5.Double-check the battery cable connections and verify all connections are properly tightened .
