4. Electrical Connections
Before performing electrical connections, ensure that the DC switch is OFF.
Since the stored electrical charge remains in a capacitor after the DC switch is
turned OFF. So it’s necessary to wait for at least 5 minutes for the capacitor to be
electrically discharged.
HYD 3K~6K-EP inverter is intended to be used in PV system with battery
storage. If not used as intended, the protection provided by the equipment may be
impaired.
Installation and maintenance of inverter, must be operated by
professional electrical engineer.
Wear rubber gloves and protective clothing (protective
glasses and boots) when working on high voltage/high current
systems such as inverter and battery systems.
Attention
PV modules generate electric energy when exposed to
sunlight and can create an electrical shock hazard. Therefore,
before connecting DC input power cable, cover PV modules using
opaque clot.
Danger
For HYD 3K~6K-EP,open-circuit voltage(Voc) of module
arrays connected in series must be ≤ 580V.
Note
The connected PV modules must have an IEC 61730 Class A ratin
