⚫
When two solar inverters are laid in the same cabinet, arrange the installation positions properly to ensure the
enough cooling effect.
Do not drop wire residue or screw into the solar drive. Failure to comply will result in damage to the solar
drive.
Never connect the power supply cables to the output terminals (U, V, W) of the solar drive. Failure to
comply will result in damage to the solar drive.
Make sure that all the connecting wires comply with the requirement of EMC and the safety standard in
the region. Use wire sizes recommended in the manual. Failure to comply may result in accidents.
Never connect the braking resistor between the DC bus terminals (P+) and (P-). Failure to comply may result
in a fire.
Do not perform the voltage resistance test on any part of the solar drive because such test has been done in
the factory. Failure to comply will result in accidents.
All peripheral devices must be connected properly under the instructions described in this manual. Failure
to comply will result in accidents.
Note the danger during the rotary running of motor when check the parameters. Failure to comply will
result in accidents.
Do not change the factory default settings of the solar drive. Failure to comply will result in damage to the
solar drive.
Avoid objects falling into the solar drive when it is running. Failure to comply will result in damage to solar
drive.
Do not start/stop the solar drive by turning the contactor ON/OFF. Failure to comply will result in damage
to the solar drive.
