Text of Warning Notices:
WARNING!
Danger of electric shock
Non-Isolated Inverter
Do not remove cover. No user serviceable parts inside. Refer servicing to qualified service
personnel.
Both AC and DC voltage sources are terminated inside this equipment. Each circuit must
be individually disconnected before servicing.
When the photovoltaic array is exposed to light, it supplies DC voltage to this equipment.
Risk of electric shock from energy stored in capacitor. After disconnecting all sources of
supply, wait 5 minutes before removing cover.
The DC conductors of this photovoltaic system are normally ungrounded but will become
intermittently grounded without indication when the inverter measures the PV array isola-
tion.
Ungrounded System: The DC lines of this PV system are not grounded and may be en-
ergized.
NOTE! Power optimizers for solar modules or data transfer via DC cables (PLC
– Power Line Communication) in the PV system can compromise the correct
function of the arc detector / interrupter.
When using such components, it is the responsibility of the system installer to en-
sure that the arc detector / interrupter functions correctly. Contact Fronius Tech-
nical Support for further information.
