ARNING
APS-6RF—high voltage and AC line-connected circuits are

present in the APS-6RF. Turn off and remove all power
sources. To reduce the risk of electric shock—make sure to
properly ground the APS-6RF.
Before field wiring, install the APS-6RF cover (Figure 4 on
page 7). When finished field wiring, install the press-fit
terminal block cover (Figure 4 on page 7) over TB1.
The only serviceable components on the APS-6RF are fuses
F1 and F2. If a fuse fails, replace with a fuse of the same type
and rating (see specs). If replacing fuse F1 (AC), remove the
vertical PC board as follows:
1. Turn off and remove all power sources.
2. Remove the two retaining screws (Figure 9).
3. Unplug the vertical PC board from the connectors as
shown in Figure 9.
Figure 9 contains an exploded view of the APS-6RF that
shows how to remove the APS-6RF PC boards from the
chassis.
