Connecting the DC Wires
WARNING: You must connect the wires that carry the DC
voltage from the PV array to the Sunny Boy 3800U in the
order described in the following procedure. Deviating
from this procedure could expose you to lethal voltages
that can cause serious injury and/or death.
WARNING: PV arrays are energized when exposed to
light. Use safe working practices when working on PV
arrays.
WARNING: Always turn OFF all AC and DC breakers and
switches in the PV system and wait a minimum of 5
minutes for the SB3800U to completely discharge before
connecting any wires to the SB3800U or disconnecting
any wires from the SB3800U. Failure to do so could
expose you to lethal voltages that can cause serious injury
and/or death.
CAUTION: Verify the polarity and the open-circuit voltage
from the PV strings before you connect the DC wires to the
SB3800U. Applying an open-circuit DC-input voltage that
exceeds the maximum DC-input-voltage range will cause
irreversible damage to the SB3800U and void the
warranty! Always verify the DC voltage before connecting
the DC-input wires from the PV array to the SB3800U. (See
the online SMA string size calculator at www.sma-
america.com to determine the correct string configuration
as shown in Figure 5-5.)
