Figure 3-1).
Figure 3-1 Sunny Boy Mounting Positions
CAUTION: The SB3800U weighs 85 lb. (38 kg.). Ensure
that the mounting surface is strong enough to hold the
weight of the SB3800U. Do not mount the Sunny Boy on
plasterboard (sheet-rock) or thin wood panelling.
CAUTION: All electrical conduits and any communication
cables must be positioned and/or sealed so that no water
can enter the inverter enclosure through these conduits and
cables.
CAUTION: Do not install the SB3800U during periods of
precipitation or high humidity (>95%). Moisture trapped
within the enclosure may cause corrosion and damage to
the electronic components.
CAUTION: If you are installing the Sunny Boy in a cabinet,
closet, or other relatively small enclosed area, you must pro-
vide sufficient air circulation to dissipate the heat generated
by the inverter.
WARNING: To prevent electrical shock or other injury,
check for existing electrical or plumbing installations in the
walls before drilling mounting holes for the Sunny Boy.
CAUTION: Outdoor installations must use raintight or wet
location hubs that meet the requirements of the Standard for
Fittings for Cable and Conduit, UL514B.
