Safety EN
WARNING! Incorrect operation or poorly executed work can cause serious injury or damage. Only qua-
lified staff are authorised to commission your inverter and only within the scope of the respective tech-
nical regulations. Read the safety rules before commissioning the equipment or carrying out
maintenance work.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar mo-
dules that are exposed to light.
- Ensure that both the AC side and the DC side of the inverter are de-energised before carrying out
any connection work.
- Only an authorised electrical engineer is permitted to connect this equipment to the public grid.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar mo-
dules.
- 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 Fro-
nius-trained service technicians.
WARNING! An electric shock can be fatal. Danger due to residual voltage in capacitors. Wait for the
capacitors to discharge. The discharge time is five minutes.
WARNING! An inadequate ground conductor connection can cause serious injury or damage. The
housing screws provide a suitable ground conductor connection for grounding the housing and must
NOT be replaced by any other screws that do not provide a reliable ground conductor connection.
WARNING! Shoddy workmanship can cause serious injury and material damage. A surge protective
device must only ever be installed and connected by a qualified electrical engineer. Follow the safety
rules. Ensure that both the AC side and the DC side of the inverter are de-energised before carrying
out any installation and connection work.
CAUTION! Risk of damage to the inverter from dirt or water on the terminals and contacts of the con-
nection area.
- When drilling, ensure that terminals and contacts in the connection area do not become dirty or
wet.
- Without a power stage set, the mounting bracket does not conform to the protection class of the
inverter as a whole and so must not be installed without the power stage set.
The mounting bracket should be protected from dirt and moisture during installation.
CAUTION! Risk of damage to the inverter as the result of incorrectly tightened terminals. Incorrectly
tightened terminals can cause heat damage to the inverter that may result in a fire. When connecting
AC and DC cables, ensure that all the terminals are tightened to the specified torque.
CAUTION! Risk of damage to inverter from overload.
- Fronius Symo: The maximum amperage when connecting to a single DC terminal is 33 A.
- Fronius Eco: The maximum amperage when connecting to a single DC terminal is 15 A.
- Connect the DC+ and DC- cables to the DC+ and DC- terminals on the inverter, taking care to en-
sure that the polarity is correct.
- The maximum DC input voltage must not exceed 1000 V DC.
