Connecting Solar Module Strings To The Inverter; Safety - Fronius Symo Advanced 10.0-3-M Operating Instructions Manual

Connecting solar module strings to the inverter

Safety

Danger due to incorrect operation and incorrectly performed work.
This can result in serious injury and damage to property.
▶
▶
Danger due to grid voltage and DC voltage from solar modules that are exposed
to light.
This may result in an electric shock.
▶
▶
Danger from grid voltage and DC voltage from solar modules.
This may result in an electric shock.
▶
▶
▶
▶
Danger due to incorrectly tightened terminals.
This may result in heat damage to the inverter, which may lead to fire.
▶
Danger due to overloading.
This may result in damage to the inverter.

IMPORTANT! The solar modules connected to the inverter must comply with the
IEC 61730 Class A standard.
WARNING!
Only qualified personnel 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!
Prior to any connection work, disconnect the inverter on the AC side and the
DC side.
Only an authorised electrical engineer is permitted to connect this equip-
ment to the public grid.
WARNING!
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!
When connecting AC and DC cables, ensure that all the terminals are
tightened to the specified torque.
CAUTION!
The maximum amperage when connecting to a single DC terminal is 33 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.
