DANGER : ELECTRICAL HAZARD!!
- PV array converts sunlight into electric power with high DC voltage and high
DC current which can cause dangerous electrical shock hazard!
- Use an opaque material to cover the PV array before wiring or cabling.
- Ensure the correct polarities are connected when DC cabling is applied.
WARNING !
- The risk of electric shock and fire exists because of high DC and AC voltages.
- Use only PV modules that are UL Listed to1000V or higher.
- Ensure the two DC switches are placed in the "OFF" position, and the PV array
is disconnected when DC conductors are connected.
- The PV Array current carrying conductors (positive or negative) must not be
referenced to ground.
ATTENTION
