Safety
WARNING! Incorrect operation or shoddy workmanship can cause serious injury or damage. Commissioning of the inverter
may only be carried out by trained personnel in accordance with the technical regulations. It is essential that you read the
"Safety Rules" chapter 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 modules that are exposed
to light.
- Make sure that both the AC side and the DC side of the inverter are de-energised before making any connections.
- 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 modules.
- The DC main switch is only to be used to de-energise the power stage set. The connection compartment 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-energised state.
- Maintenance and servicing in the power stage set of the inverter must only be carried out by Fronius-trained service
technicians.
WARNING! An electric shock can be fatal. Danger due to residual voltage in capacitors.
Wait for the capacitors to discharge. Discharge time is 5 minutes.
CAUTION! An inadequate ground conductor connection can cause serious injury or damage. The housing screws provide
a suitable ground conductor connection for earthing the housing and must NOT be replaced by any other screws that do
not provide a reliable ground conductor connection.
CAUTION! Risk of damage to the inverter from dirt or water on the terminals and contacts of the connection area
- When drilling, ensure that terminals and contacts in the connection area do not become dirty or wet.
- The wall bracket without a power stage set does not conform to the protection class of the inverter as a whole, and
therefore must not be installed without a power stage set.
The wall 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 and 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.
- The maximum amperage when connecting to a single DC terminal is 20 A.
- Connect the DC+ and DC- cables to the DC+ and DC- terminals on the inverter, taking care to ensure that the polarity is
NOTE! Degree of protection IP 55 is only applicable if the inverter is permanently attached to the wall bracket with screws.
Degree of protection IP 20 applies to the wall bracket with no inverter.
