Information
This symbol accompanies notes that call attention to supplementary information that you
should know and use to ensure optimal operation of the system.
General Warnings
All electrical installations must be done in accordance with the local and National
Electrical Code ANSI/NFPA 70.
Before installing or using the Sunny SensorBox, read all of the instructions, cautions, and
warnings on the Sunny SensorBox, the PV array, in this Installation Guide and in User
Manual.
PV arrays produce electrical energy when exposed to light and thus can create an
electrical shock hazard. Wiring of the PV-arrays shall only be performed by qualified
personnel.
Only use the plug-in power supply delivered with the Sunny SensorBox. Use of alternate
power supplies will void the warranty.
