DANGER : ELECTRICAL HAZARD!!
- PV arrays convert sunlight into electric power with high DC voltage and high
DC current which can cause dangerous electrical shock!
- Use opaque material to cover the PV arrays before wiring or cabling.
- Ensure the correct polarities are connected when DC cabling is applied.
- Before plug in the DC connectors, please notice the polar of connectors.
Reverse positive and negative voltage will make damage.
WARNING !
- The inverter may overheat and catch fire under fault conditions.
- Only PV modules that are listed with system voltage under 1100V are permitted
for use.
- Make sure the DC switch is in the “OFF” position, and disconnect the PV array
before plug in/out the DC connectors.
- Inverter warranty void if the DC input voltage exceeds 1100 Vdc.
- The PV Array current carrying conductors (positive or negative) must not be
referenced to ground.
ATTENTION
