4. Electrical connections
Before making any electrical connections, make sure that the DC circuit breaker is switched off. The
stored electrical charge remains in the capacitor after the DC circuit breaker has been switched off, for
safety reasons, wait 5 minutes for the capacitor to discharge completely.
The PV modules generate electricity when exposed to sunlight, and can
create electric shocks. Therefore, before connecting the DC power cord,
cover the PV modules with a dark covering.
The inverter must be installed and serviced by a professional
electrician. Wear protection equipment when working on high
voltage/high current systems such as inverters and battery systems.
For the 3PH HYD5000-HYD20000-ZSS inverter, the open-circuit voltage
(Voc) of the strings related to the modules connected in series must be
≤ 1000V
The PV modules must have an IEC 61730 classification of Class A.

There are two ways to measure the currents exchanged with the grid; refer to the technical notes in
the website www.zcsazzurro.com for more details.
