Fronius Symo 10.0-3-M Installation Instructions

Connecting solar module strings to the inverter
Safety
WARNING!
Danger due to incorrect operation and incorrectly performed work.
This can result in serious injury and damage to property.
▶
Only qualified staff are authorised to commission your inverter and only
within the scope of the respective technical regulations.
▶
Read the Installation and Operating Instructions before installing and com-
missioning the equipment.
WARNING!
Danger due to grid voltage and DC voltage from solar modules that are exposed
to light.
This may result in an electric shock.
▶
Ensure that both the AC side and the DC side of the inverter are de-ener-
gised before carrying out any connection work.
▶
Only an authorised electrical engineer is permitted to connect this equip-
ment to the public grid.
WARNING!
Danger due to grid voltage and DC voltage from solar modules.
This may result in an electric shock.
▶
The DC main switch is only to be used to de-energise the power stage set.
The connection area is still live when the DC main switch is switched off.
▶
Ensure that the power stage set and connection area are disconnected from
one another before carrying out any maintenance or service tasks.
▶
The power stage set, which is enclosed in a separate housing, must only be
disconnected from the connection area when in a de-energized state.
▶
Maintenance and servicing in the power stage set of the inverter must only
be carried out by Fronius-trained service technicians.
CAUTION!
Danger due to incorrectly tightened terminals.
This may result in heat damage to the inverter, which may lead to fire.
▶
When connecting AC and DC cables, ensure that all the terminals are
tightened to the specified torque.
CAUTION!
Danger due to overloading.
This may result in damage to the inverter.
▶
Fronius Symo: The maximum amperage when connecting to a single DC ter-
minal is 33 A.
▶
Fronius Eco: The maximum amperage when connecting to a single DC ter-
minal is 15 A.
▶
Connect the DC+ and DC- cables to the DC+ and DC- terminals on the in-
verter, taking care to ensure that the polarity is correct.
▶
Observe the maximum DC input voltage.
