Safety instructions
This topic describes the electrical connections of the inverter HYD 5K
... 20KTL-3PH. Read this section thoroughly and carefully before
connecting the cables.
DANGER
Electrical voltage at the DC connections
•
Ensure that the DC switch is OFF before establishing the
electrical connection. The reason is that the electrical charge
remains in the capacitor after the DC switch has been
switched off. Therefore, at least 5 minutes must lapse before
the capacitor has been electrically discharged.
DANGER
Electrical voltage
•
PV modules generate electrical energy when exposed to
sunlight, and this may present an electrical shock hazard.
Therefore, cover the PV modules with an opaque sheet
before connecting to the DC input power cable.
DANGER
Electrical voltage at the DC connections
•
Wear rubber gloves and protective clothing (safety goggles
and boots) when working on high voltage/high current
systems such as inverter and battery systems.
