Environment:

Resolution:
Please refer to the Data Bulletin 3110DB0401R0410, Dated 6/2010, see attached below. The wiring diagrams shown on Page 1, Figures 1B, 1D or 1F can be used on a photovoltaic system and be within the UL listing of the switch. The wiring diagram shown on Page 2, Figure 2, can be used but is not within the UL listing of the switch. However, we have self-certified this method of wiring, for a photovoltaic system only, when applied per the limitations outlined in the Current Ratings table located below Figure 2.
