Servicing the APS-6RF
The only serviceable components on the APS-6RF are fuses F1 and F2. If
a fuse fails, replace it with a fuse of the same type and rating:
• F1 AC protection - 4A, 3 AG
• F2 Battery protection - 10A, 3 AG
To replace either fuse remove the vertical PC board as follows:
1. Turn off and remove all power sources.
2. Remove plastic cover.
3. Remove the two retaining screws securing vertical board.
4. Unplug the vertical PC board from the connectors.
5. Replace fuses as required.
6. Reinstall board in reverse order, install plastic cover and connect all
power.
The figure below illustrates the location of the fuses.
