Cautions and Warnings
WARNING: A Warning describes a hazard to personnel. It
calls attention to a procedure or practice, which, if not correct-
ly performed or adhered to, could result in personal injury.
CAUTION: A Caution describes a hazard to equipment. It calls
attention to an operating procedure or practice, which, if not
correctly performed or adhered to, could result in damage to or
destruction of part or all of the SMA equipment and/or other
equipment connected to the SMA equipment.
Warnings and Cautions may also be accompanied by one or more of the safety and
hazard symbols described above to indicate the type of hazard described therein.
All electrical installations must be done in accordance with
the local and National Electrical Code ANSI/NFPA 70.
The Sunny Boy contains no user-serviceable parts. Always
return the unit to an SMA authorized Service Center for
repairs and maintenance.
Before installing or using the Sunny Boy, read all of the
instructions, cautions, and warnings on the Sunny Boy, the
PV array, and in this Installation Guide.
You must not connect the Sunny Boy to the electrical utility
grid until you have received prior approval from the utility
company. This connection must be made only by qualified
personnel.
PV arrays produce electrical energy when exposed to light
and thus can create an electrical shock hazard.
Completely cover the surface of all PV-arrays with opaque
(dark) material before wiring them.
The Sunny Boy has a heat sink on its top surface to help
cool the internal components. This heat sink can reach
temperatures as high as 158° F (70° C). To avoid the risk
of burns, never touch the Sunny Boy’s heat sink while the
unit is in operation.
