Safety Rules Explanation
General
DANGER! Indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING! Indicates a potentially hazardous situation which, if not avoided, will
result in death or serious injury.
CAUTION! Indicates a potentially harmful situation which, if not avoided, may result in minor and moderate injury or property damage.
NOTE! Indicates a risk of flawed results and possible damage to the equipment.
IMPORTANT! Indicates tips for correct operation and other particularly useful information.
It does not indicate a potentially damaging or dangerous situation.
If you see any of the symbols depicted in the "Safety rules," special care is required.
The device is manufactured using state-of-the-art technology and according
to recognized safety standards. If used incorrectly or misused, however, it can
cause
- injury or death to the operator or a third party,
- damage to the device and other material assets belonging to the operator,
- inefficient operation of the device
All persons involved in commissioning, maintaining and servicing the device
must
- be suitably qualified,
- have knowledge of and experience in dealing with electrical installations
and
- read and follow these operating instructions carefully
The operating instructions must always be at hand wherever the device is being used. In addition to the operating instructions, attention must also be paid
to any generally applicable and local regulations regarding accident prevention and environmental protection.
All safety and danger notices on the device
- must be kept in a legible state
- must not be damaged/marked
- must not be removed
- must not be covered, pasted or painted over
For the location of the safety and danger notices on the device, refer to the
section headed "General" in the operating instructions for the device.
Before switching on the device, remove any faults that could compromise
safety.
Your personal safety is at stake!

Utilization in Accordance with
"Intended Purpose"
The device is to be used exclusively for its intended purpose.
Utilization for any other purpose, or in any other manner, shall be deemed to
be "not in accordance with the intended purpose." The manufacturer shall not
be liable for any damage resulting from such improper use.
Utilization in accordance with the "intended purpose" also includes
- carefully reading and obeying all the instructions and all the safety and
danger notices in the operating instructions
- performing all stipulated inspection and servicing work
- installation as specified in the operating instructions
The following guidelines should also be applied where relevant:
- Regulations of the utility regarding energy fed into the grid
- Instructions from the solar module manufacturer
Environmental
Conditions
Qualified Service
Engineers
Operation or storage of the device outside the stipulated area will be deemed
as "not in accordance with the intended purpose." The manufacturer is not responsible for any damages resulting from unintended use.
For exact information on permitted environmental conditions, please refer to
the "Technical data" in the operating instructions.
The servicing information contained in these operating instructions is intended
only for the use of qualified service engineers. An electric shock can be fatal.
Do not perform any actions other than those described in the documentation.
This also applies to those who may be qualified.
All cables and leads must be secured, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or inadequately dimensioned cables and leads must be immediately repaired by authorized personnel.
Maintenance and repair work must only be carried out by authorized personnel.
It is impossible to guarantee that externally procured parts are designed and
manufactured to meet the demands made on them, or that they satisfy safety
requirements. Use only original replacement parts (also applies to standard
parts).
Do not carry out any modifications, alterations, etc. without the manufacturer's
consent.
Components that are not in perfect condition must be changed immediately.
Safety Measures
at the Installation
Location
6
When installing devices with openings for cooling air, ensure that the cooling air can enter
and exit unhindered through the vents. Only operate the device in accordance with the degree of protection shown on the rating plate.
EMC Device Classifications
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- Satisfy the emissions criteria for residential and industrial areas.
This is also true for residential areas in which the energy is supplied from the public low-voltage grid.
EMC device classification as per the rating plate or technical data.

EMC Measures
Electrical Installations
Protective Measures against
ESD
In certain cases, even though a device complies with the standard limit values
for emissions, it may affect the application area for which it was designed (e.g.,
when there is sensitive equipment at the same location, or if the site where the
device is installed is close to either radio or television receivers). If this is the
case, then the operator is obliged to take appropriate action to rectify the situation.
Electrical installations must only be carried out according to relevant national
and local standards and regulations.
Danger of damage to electrical components from electrical discharge. Suitable
measures should be taken to protect against ESD when replacing and installing components.
Safety Measures
in Normal Operation
Only operate the device when all protection devices are fully functional. If the
protection devices are not fully functional, there is a risk of
- injury or death to the operator or a third party,
- damage to the device and other material assets belonging to the operator,
- inefficient operation of the device
Any safety devices that are not functioning properly must be repaired by authorized personnel before the device is switched on.
Never bypass or disable protection devices.

General
EN-US
Safety
WARNING! An electric shock can be fatal. Danger from grid voltage and DC volt-
age from solar modules.
- The connection area should only be opened by a licensed electrician.
- The separate power stage set area should only be disconnected from the
connection area after first being disconnected from the grid power.
- The separate power stage set area should only be opened by Fronius-trained
service technicians.
- Never work with live wires! Before any connection work, make sure that the
inverter's AC and DC wires are not charged.
- In the USA, all electrical installations must be in accordance with the National
Electrical Code, ANSI/NFPA 70, and any other codes and regulations applicable to the installation site.
- Installations in Canada must comply with the applicable Canadian standards.
Never work with live wires! Before any connection work, make sure that the inverter's AC and DC wires are not charged.
WARNING! An electric shock can be fatal. Danger from residual voltage from capacitors.
You must wait until the capacitors have discharged. Discharge takes 5 minutes.
Use a suitable measuring tool to ensure that the capacitors are discharged.
WARNING! Incorrect operation and work performed incorrectly can cause serious injury and damage! Only qualified staff are authorized to install your inverter
and only within the scope of the respective technical regulations. It is essential
