AC Voltage Configuration
Opening the Sunny Boy 3800U
Remove the four screws and lock washers that attach the cover of the SB3800U. Place
the cover, screws, and lock washers aside where they will be out of your way while
connecting the wires and cables to the Sunny Boy.
CAUTION: Be careful not to misplace the screws or the lock
washers, as all four screws and lock washers are required to
ensure that the cover is grounded properly and is fully sealed
to the case. Handle the cover carefully, as even minor damage
to the cover could result in an inadequate seal between the
cover and the case, thus allowing moisture to enter the case
and damage the sensitive electronic components.
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 elec-
tronic components.
