Safety
WARNING! An electric shock can be fatal. Danger from grid voltage and DC volt-
age from solar modules.
- The connection area should only be opened by a licensed electrician.
- The separate power stage set area should only be disconnected from the
connection area after first being disconnected from the grid power.
- The separate power stage set area should only be opened by Fronius-trained
service technicians.
- Never work with live wires! Before any connection work, make sure that the
inverter's AC and DC wires are not charged.
- In the USA, all electrical installations must be in accordance with the National
Electrical Code, ANSI/NFPA 70, and any other codes and regulations applicable to the installation site.

Never work with live wires! Before any connection work, make sure that the inverter's AC and DC wires are not charged.
WARNING! An electric shock can be fatal. Danger from residual voltage from capacitors.
You must wait until the capacitors have discharged. Discharge takes 5 minutes.
Use a suitable measuring tool to ensure that the capacitors are discharged.
WARNING! Incorrect operation and work performed incorrectly can cause serious injury and damage! Only qualified staff are authorized to install your inverter
and only within the scope of the respective technical regulations. It is essential
