Arc Detector / Interrupter; Warning Notices Affixed To The Device - Fronius Primo 3.8-1 208-240 Manual De Instrucciones

Arc Detector / In- The inverter has an integrated arc detector / interrupter, which detects and deletes serial
terrupter arcs.
A serial arc may occur after the following example errors or situations:
-
-
-
-
-
If an arc is detected, the power is shut down and the grid power feed operation is interrupt-
ed. A status code appears on the display.
The status code on the display must be reset manually before the grid power feed opera-
tion can be resumed.
The power shut down also deletes the serial arc.
Warning Notices The inverter contains and displays warning notices and safety symbols. These warning no-
Affixed to the De- tices and safety symbols must NOT be removed or painted over. The notices and symbols
vice warn against operating the equipment incorrectly, as this may result in serious injury and
damage.
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.

poorly connected DC plug
defective solar module connection sockets
high resistance solder connections between the cells of a solar module
incorrect cable connected to the input terminal of an inverter
defective DC cables that allow a connection to the ground.
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.
