AX Plus 5-15kW 3ph Hybrid Inverter
DANGER!
Before electrical connections, please make sure that the inverter switch
and all switches connected to the inverter are set to „OFF", otherwise
electric shock may occur!
Ensure that the inverter is undamaged and all cables are voltage free
before performing electrical work. Do not close the Ac circuit breaker
until the electrical connection is complete.
WARNING!
Damage to the product caused by incorrect wiring is not covered by the
warranty.
Electrical connection must be performed by professionals.
Operators must wear proper personal protective equipment during
electrical connections.
All cables used in the PV generation system must be firmly attached,
properly insulated, and adequately dimensioned.
DANGER!
The PV string will generate lethal high voltage when exposed to sunlight.
Respect all safety instructions listed in relevant documents about PV
strings.
WARNING!
Make sure the PV array is well insulated to ground before connecting it
to the inverter.
Make sure the maximum DC voltage and the maximum short circuit
current of any string never exceed inverter permitted values specified
in „Technical Data" Check the positive and negative polarity of the PV
strings, and connect the Pv connectors to corresponding terminals only
after ensuring polarity correctness.
During the installation and operation of the inverter, please ensure that
the positive or negative electrodes of PV strings do not short-circuit to
the ground. Otherwise, an AC or Dc short-circuit may occur, resulting in
equipment damage. The damage caused by this is not covered by the
warranty.
Electric arc or contactor over-temperature may occur if the PV
connectors are not firmly in place, and SUNGRoW shall not be held liable
for any damage caused.
If the Dc input cables are reversely connected and the Dc switch has
been rotated to „ON", do not operate immediately. Otherwise, the
inverter may be damaged. Please turn the Dc switch to „OFF" and
remove the Dc connector to adjust the polarity of the strings when the
string current is lower than 0.5 A.
