When the photovoltaic array is exposed to light, it supplies a DC voltage to the Inverter,
a shock hazard may exist due to output wires or exposed terminals.
To reduce the risk of shock during installation, cover the array with an opaque (dark)
material and ensure that the Disconnect Device in the inverter is set to OFF before
commencing any wiring.
Before commencing AC wiring, please ensure all AC circuit breakers are switched off.
During operation of electrical devices, certain parts are under dangerous voltage.
Inappropriate handling can lead to physical injury and material damage.
Always adhere to the installation regulations.
Installation may only be conducted by certified electricians.
The maximum open circuit voltage of the PV Array must not exceed 500Vdc (H2.5) /
600Vdc (H3/ H3A/ H4A/ H5A) .
