Electrical connections
Danger
！
Ensure that the solar cell array should be covered by light tight materials, before
electrical connecting, otherwise, the solar cell array would produce high voltage under
the sun to cause casualties.
Warning
！
If inverter damage caused by the following circumstances will be beyond the warranty
scope of our company.
●
Ensure that the max. short-circuit of DC side is in the inverter allowable range
when configuring PV arrays, otherwise, inverter may be caused non-recoverable
damage.
●
Ensure that the open circuit voltage of JNPxH shall not exceed 880V when
configuring PV arrays, otherwise, inverter may be caused non-recoverable
damage
。
●
It would influence the machine features and may cause machine damage if the
installation environment is selected improperly.
●
Do not install the inverter in inflammable, explosive place or inflammable,
explosive materials storage .
●
Don’t install the inverter in explosive dangerous place.
●
Don’t install the inverter in place where vulnerable to lightning strike.
●
Don’t install the inverter in place where have more salt fog.
●
When running the inverter, please ensure good ventilation.
●
Inverter should be installed erectly, and ensure the heat sink, fans etc. are without
shelter.
