Inserting String Fuses into the Fronius IG TL
General The steps described in the ‘Inserting String Fuses into the Fronius IG TL’ section should
only be carried out if the solar module manufacturer requires the use of string fuses for op-
eration.
Selecting string
fuses If the solar module manufacturer requires the use of string fuses for operation, select string
fuses according to the information from the solar module manufacturer or according to the
‘Criteria for the Proper Selection of String Fuses’ section:
-
max. 20 A per fuse holder
- max. 6 DC inputs
- max. 11 A per measuring channel if solar module string monitoring is activated and
being used
- max. 20 A of total input current
- Fuse dimensions: Diameter 10.3 x 35 - 38 mm
Safety
IMPORTANT!
- Follow all solar module safety instructions
- Follow all solar module manufacturer requirements
WARNING! An electric shock can be fatal. Danger from grid voltage and DC volt-
age from solar modules.
-
The DC main switch is used only to switch off power to the power stage set.
When the DC main switch is turned off, the connection area is still energized.
- Only licensed electricians should access the connection area.
- All maintenance and service work should only be carried out when the power
stage set has been disconnected from the connection area.
- Maintenance and service work on the inverter power stage set should only
be carried out by Fronius-trained personnel.
WARNING! An electric shock can be fatal. Danger from residual voltage from ca-
pacitors.
You must wait until the capacitors have discharged. Discharge takes 3 minutes.
