Fuse Replacement

DBK34A contains four MINI ATO fuses that can be replaced by the user. Note that you should always

check your unit for blown fuses prior to sending it back to the factory for repair. This could save you time

and money.

The following table indicates the probable reason that a particular fuse may have blown, and includes part

numbers and fuse rating.

Fuse Rating Probable Cause of Blowing Fuse Replacement Fuse

F1 7.5 A Auxiliary Battery overload. 7.5A MINI ATO, LITTLEFUSE# 297-07.5

F2 7.5 A Output overload. 7.5A MINI ATO, LITTLEFUSE# 297-07.5

F3 7.5 A Output overload. 7.5A MINI ATO, LITTLEFUSE# 297-07.5

DBK34A, Fuse Location Reference

To replace a fuse:

1. Disconnect the DBK34A from loads and from supply power.

2. Remove the DBK34A’s cover plate. This requires the removal of 4

screws (2 per side).

3. Examine the fuses (F1 through F4) to see which, if any, have blown.

Note that you can usually see the blown element through the fuse’s

transparent casing.

4. Replace the blown fuse with the appropriate replacement fuse (see

preceding table). Note that the fuse value is present on top of the fuse;

also, the fuses are color coded as an aid to identification.

5. Replace the DBK34A cover and secure with screws (removed in step 2).
