6. Turn the slotted screw clockwise until tight to secure the
front cover.
7. Set the POWER switch to the OFF position before

necessary when installed in accordance with the guidelines
specified in this manual.

Installation
ATTENTION:
Most code requires that upstream
branch protection be provided to protect input power
wiring. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ƽ
This DC3N model has 15-amp line fuses preinstalled on
fuse holders 501 and 502 (FU501 and FU502). When
replacing the line fuses, use fast acting fuses rated for 250
VAC or higher. See Figure 3, page 6, for fuse holder
location, and Table 1, page 13, for recommended line fuse
sizes.
