IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

General
These operating instructions contain important instructions for the inverter that must be followed during installation and maintenance of the inverter.
The inverter is designed and tested according to international safety requirements, but as with all electrical and electronic equipment, certain precautions must be observed when installing and/or operating the inverter.
To reduce the risk of personal injury and to ensure the safe installation and operation of the inverter, you must carefully read and follow all instructions and safety instructions in these operating instructions.
Failure to follow these instructions and other relevant safety procedures may result in voiding of the warranty and/or damage to the inverter or other property!
Safety
The following section “Safety“ contains various warnings. A Warning describes a hazard to equipment or personnel. It calls attention to a procedure or practice, which, if not correctly performed or adhered to, could result in damage to or destruction of part or all of the Fronius inverter and/or other equipment connected to the Fronius inverter or personal injury.
Electrical installations
All electrical installations must be carried out in accordance with the National Electrical Code, ANSI/NFPA 70, and any other codes and regulations applicable to the installation site.
For installations in Canada, the installations must be done in accordance with applicable Canadian standards.

Safety

WARNING! Incorrect operation and work performed incorrectly can cause serious injury and damage to property. Only qualified staff are authorized to commission your inverter and only within the scope of the respective technical regulations. Do not start operation or carry out maintenance work until you have read the “Safety Instructions” chapter.
WARNING! An electric shock can be fatal. Danger from grid voltage and DC voltage from solar modules that are exposed to light.
– Never work with live wires! Prior to all connection work, make sure that the AC and DC wires are not charged.
– Only an authorized electrician is permitted to connect this inverter to the public grid.
WARNING! An electric shock can be fatal. Danger from grid voltage and DC voltage from solar modules.
– The DC main switch is used only to switch off power to the power stage set. When the DC main switch is turned off, the connection area is still energized.
– All maintenance and service work should only be carried out when the power stage set has been disconnected from the connection area.
– The separate power stage set area should only be disconnected from the connection area after first being disconnected from the grid power.
– Maintenance and service work on the inverter power stage set should only be carried out by Fronius-trained personnel.
WARNING! An electric shock can be fatal. Inadequately sized electrical components can cause serious injuries to persons and damage to (or loss of) property.
– All electrical installations must be carried out in accordance with the National Electrical Code, ANSI/ NFPA 70, and any other codes and regulations applicable to the installation site.
– For installations in Canada, the installations must be done in accordance with applicable Canadian standards.
– Use 194 °F (90 °C), copper wire for all grounding wires (see NEC table 250.122).
– Voltage drop and other considerations may dictate larger size wires be used.
– Use only solid or stranded wire. Do not use fine stranded wire.
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.
WARNING! An inadequate ground conductor connection can cause serious injuries to persons and damage to (or loss of) property. The housing screws provide an adequate protective conductor connection for grounding the housing and should not be replaced under any circumstances by other screws that do not provide a proper ground conductor connection.
WARNING! Work performed incorrectly can cause serious injury and damage. Installation and connection of overvoltage protection can only be performed by licensed electricians. Observe the safety rules. Never work with live wires! Prior to all installation and connection work, make sure that the AC and DC wires are not charged.
CAUTION! The inverter can be damaged by soiling or water on the terminals and contacts of the connection area.
– When drilling, make sure that terminals and contacts in the connection area do not become soiled or wet.
– The wall bracket without the power stage set does not possess the same degree of protection as the complete inverter and, therefore, should not be attached without a power stage set.
Protect the wall bracket from soiling and moisture during installation.
CAUTION! Danger of damaging the inverter due to improperly connected terminals. Improperly connected terminals can cause thermal damage to the inverter and may cause a fire. When connecting the AC and DC cables, make sure that all terminals are  tightened securely using the proper torque.
CAUTION! Overloading the inverter may damage it.
– Observe the maximum current carrying capacity of different power categories (see Table A).
– Only connect a maximum of 33 A to each DC terminal.
– Connect the DC+ and DC- cables to the correct DC+ and DC- terminals on the inverter.
– Observe the maximum DC input voltage.

Table A

Power category| Current carrying capacity
10.0-1 208-240 / 11.4-1 208-240 / 12.5-1 208-240 / 15.0-1 208-240| 33 A / 18 A

CAUTION! Danger of short circuit from loose metal parts from knockouts. Loose metal parts in the inverter may cause short circuits when the inverter is powered up. When removing knockouts, make sure that
– no loose metal parts fall into the inverter,
– any metal pieces that do fall into the inverter are removed immediately.

NOTE! Degree of protection NEMA4X is only ensured when the inverter is mounted and firmly screwed into the wall bracket.
The wall bracket without inverter has no NEMA protection
NOTE! Photovoltaic modules exposed to light supply current to the inverter.
NOTE! When using the cable inlets at the back, take care to seal them according to degree of protection NEMA4X before operating outdoors.
NOTE! When installing outdoors, only use waterproof conduit fittings and conduits. Conduit fittings and conduits are not part of the scope of supply for the inverter.
NOTE! When connecting aluminum cables:
– follow all national and international guidelines regarding the connection of aluminum cables,
– follow the instructions of the cable manufacturer,
– perform an annual check to ensure that the cables are firmly attached according to the proper torque.
NOTE! When connecting DC cables, ensure the polarity is correct.
NOTE! Form a wire loop according to NEC using all wires.
NOTE! Follow general ESD guidelines when handling option cards.
NOTE! Fronius will not bear any costs for loss of production, or installations, etc., which may arise due to a detected electric arc and its consequences. Fronius accepts no liability for fires which may break out despite integrated arc detection/interruption (e.g., due to a parallel arc).
NOTE! Before an inverter can be reset following a detected electric arc, check the entire affected photovoltaic system for any damage.
NOTE! If the cable insulation of the AC cable is not designed for a maximum of 1000 V, AC and DC cables must not be crossed when connecting in the inverter.
If crossing the cables during connection is unavoidable, the AC cable must be laid in one piece of the protective hose supplied with the inverter.
AC and DC cables can only be laid together if the insulation on both cables is designed for the max. possible voltage of 1000 V.
NOTE!
– Make sure that the grid neutral conductor is grounded. For IT networks (isolated networks without grounding), this is not the case, and operation of the inverter is not possible.
– To use the inverter, a neutral conductor connector is required (depending on grid configuration, see page 24).
The infeed of the inverter can be adversely affected by a neutral conductor with small dimensions.
Therefore, the neutral conductor must have the same dimensions as the other current-bearing conductors.

Fire Prevention

CAUTION! Risk of damage to inverters and other live photovoltaic system components due to poor or unprofessional installation.
Poor or unprofessional installation can cause overheating of cables and terminal connections and result in arcs. These can cause heat damage, which in turn may lead to fires.

Observe the following when connecting AC and DC cables:
– Tighten all terminals to the torque specified in the operating instructions
– Tighten all grounding terminals (PE / GND), including unused ones, to the torque specified in the operating instructions
– Do not overload cables
– Check cables for damage and verify that they are laid correctly
– Take note of the safety instructions, operating instructions and any local connection regulations
Using fastening screws, always screw the inverter firmly to the wall bracket to the torque specified in the operating instructions.
Ensure that the fastening screws are tight before starting the inverter!

Data communication and Solar Net

Fronius Solar Net and Data Interface

Fronius developed Solar Net to make these system add-ons flexible and capable of being used in a wide variety of different applications. Fronius Solar Net is a data network that enables several inverters to be linked to the system add-ons.
Fronius Solar Net is a bus system with ring topology. Just one suitable cable is enough to provide communication between one or more inverter connected to Fronius Solar Net and a system add-on.
Different system add-ons are automatically recognized by Fronius Solar Net.
In order to distinguish between several identical system add-ons, each one must be assigned a unique number.
In order to clearly define each inverter in Fronius Solar Net, each inverter must also be assigned an individual number.
You can assign individual numbers as per the “SETUP Menu” section in this manual.
More detailed information on individual system upgrades can be found in the relevant operating instructions or on the internet at http://www.fronius.com
More detailed information on cabling DATCOM components can be found at

Data communication area

Depending on the model, the inverter may be equipped as follows:

• with the Fronius Datamanager 2.0 plug-in card
•  with another Fronius plug-in card
• without plug-in card(s)

In this manual the device with the Fronius Datamanager 2.0 plug-in card is described.

If several DATCOM components are linked together, a terminating plug must be connected to every free
IN or OUT connection on a DATCOM component. For inverters with a Fronius Datamanager plug-in
card, two terminating plugs are supplied with the inverter.
(4)| The ‘Solar Net’ LED indicates whether the Fronius Solar Net power supply is available The ‘Solar Net’ LED is on:the power supply for data communication within the Fronius Solar Net / interface protocol is OK
The ‘Solar Net’ LED flashes briefly every 5 seconds:
data communication error in the Fronius Solar Net
– Overcurrent (current flow > 3 A, e.g. resulting from a short circuit in the Fronius Solar Net ring)
– Undervoltage (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if there are too many DATCOM components on the Fronius Solar Net and not enough electrical power is available)In this case, power for the DATCOM components must be supplied by connecting an additional powersupply to one of the DATCOM components. To detect the presence of an undervoltage, check
some of the other DATCOM components for faults as required.
After cutting out because of overcurrent or undervoltage, the inverter attempts to restore the power supply in the Fronius Solar Net every 5 seconds while the fault is stillpresent.
Once the fault is rectified, power to the Fronius Solar Net will be restored within 5 seconds.

Example

Recording and archiving data from the inverter and sensor using a Fronius Datamanager and a Fronius Sensor Box:

Data network with 3 inverters and a Fronius Sensor Box:
– Inverter 1 with Fronius Datamanager
– Inverters 2 and 3 without Fronius Datamanager!
= Terminating plug
The external communication (Fronius Solar Net) takes place on the inverter via the data communication area. The data communication area contains two RS 422 interfaces as inputs and outputs. RJ45 plug connectors are used to make the connection.
IMPORTANT! Since the Fronius Datamanager functions as a data logger, the Fronius Solar Net ring must not include any other data logger. Only one Fronius Datamanager per Fronius Solar Net ring! Any other Fronius Datamanagers must be removed and the unoccupied option card compartment sealed off using the blanking cover (42,0405,2020
– available from Fronius as an optional extra); alternatively, use an inverter without Fronius Datamanager (light version).
