General

The Fronius IG Plus is designed so that it does not require additional
maintenance.
However, there are a few points to keep in mind during operation to ensu-
re that the inverter functions optimally.
WARNING! An electrical shock can be fatal. Danger from grid
voltage and DC voltage from solar modules.
- The connection area should only be opened by a licensed
electrician.
- The separate power stage set area should only be discon-
nected from the connection area after first being discon-
nected from the grid power.
- The separate power stage set area should only be opened
by Fronius-trained service personnel.
Never work with live wires! Prior to all connection work, make
sure that the AC and DC wires are not charged.
The DC main switch is only used to switch off power to the
power stage set. When the DC main switch is turned off, the
connection area is still energized.
These servicing instructions are for use by qualified personnel
only. To reduce the risk of electric shock, do not perform any
servicing other than that specified in the operating instructions.
WARNING! An electrical shock can be fatal. Danger from
residual voltage from capacitors.
You must wait until the capacitors have discharged. Discharge
takes 5 minutes.
