EN-US Symbol Explanations – Installation Position The inverter is suitable for vertical installation on a vertical wall or pillar. The inverter is suitable for horizontal installation. The inverter is suitable for installation on an inclined surface. Do not install the inverter on an inclined surface with the connection sockets facing upwards. Do not install the inverter in a sloping position on a vertical wall or pillar.
Do not install the inverter so that it is overhanging with the connection sockets facing downwards. Do not install the inverter on the ceiling.
Intended Use EN-US Choosing the Location The inverter is designed exclusively to be connected and used with nongrounded solar modules. The solar modules cannot be grounded at either the positive or negative pole. The solar inverter is designed exclusively to convert direct current from solar modules into alternating current and feed this power into the public grid.
Selecting a Location – General Information for Fronius Primo 10.0–15.0 Please note the following criteria when choosing a location for the inverter: Only install on a solid surface Max. ambient temperatures: -40°F to +140°F (-40°C to +60°C) 8 in. 200 mm Relative humidity: 0–100% 4 in. 100 mm The air flow direction within the inverter is from right to top (cold air intake on the right, hot air outflow at the top). 4 in.
EN-US Installation information Auswahl von Dübel und Schrauben IMPORTANT! Je nach Untergrund ist unterschiedliches Befestigungsmaterial für die Montage der Montagehalterung erforderlich. Das Befestigungsmaterial ist daher nicht im Lieferumfang des Wechselrichters enthalten. Der Monteur ist für die richtige Auswahl des Befestigungsmaterials selbst verantwortlich. Screw Recommendation To install the inverter, the manufacturer recommends using steel or aluminum screws with a diameter of 0.2–0.3 in.
Installing the Inverter on a Mast ? Fronius Primo 208-240 Installation Help Example of a mast mounting kit 12 For installation of the inverter on a mast or beam, Fronius recommends using the "Pole clamp" (order no. SZ 2584.000) mast mounting kit from Rittal GmbH.
General EN-US Notes on the Knockouts The wall bracket contains several knockouts of different sizes. When knocked out, the openings are used for the inputs of various wires. 1/2 in. for data communication cable (DATCOM) for Fronius Primo 3.8-8.2: 3/4 in. for AC and DC cables for Fronius 10.0-15.0: 3/4 in. 1 1/4 in. for AC and DC cables * A grounding electrode terminal may be required depending on local regulations.
* When drilling out the knockouts at the back, place the wall bracket on an even surface with the back upwards so that shavings and pieces of metal can fall out of the wall bracket. Attach appropriate conduits to all knocked/drilled out knockouts. In the event of installation outside, only use watertight conduits and conduit fittings. Conduits and conduit fittings are not included with the inverter.
Suitable Grids EN-US Suitable Grids Inverters can be operated on the following grids: 208 V Delta - Corner Grounded, without neutral conductor 208 V Delta: 120 V WYE, with neutral conductor 220 V Delta - Corner Grounded, without neutral conductor 220 V Delta: 127 V WYE, with neutral conductor 240 V Delta - Corner Grounded, without neutral conductor 240 V: 120 V WYE, with neutral conductor 240 V: 120 V split phase, with neutral conductor - 50 Hz (220 V Delta - Corner Grounded, 50 Hz, without neutral condu
Notes on connection area Permitted cables Cables with the following design can be connected to the AC and DC terminals of the inverter: Cu / Al Cu - Copper or aluminum: round, solid Copper: round, stranded, up to conductor class 4 Fronius Primo 3.8–8.2 Fronius Primo 10.0–15.0 Cable cross-sections: Cable cross-sections: Cu : min.

After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid-free and alkali-free Vaseline. 3 Then immediately connect it to the terminal. Repeat the steps above whenever the cable is disconnected and then reconnected.
Notes on grid connection Monitoring the Grid AC Connection IMPORTANT! The resistance in the leads to the AC-side connection terminals must be as low as possible for optimal functioning of grid monitoring. NOTE! Fronius Primo 3.8–8.2 only: To ensure a proper ground connection, all 3 grounding terminals GND must be tightened with the specified torque during installation. NOTE! Loop the AC cables when connecting them to the AC terminals: Fronius Primo 3.8–8.2: min. 4 in. (102 mm) Fronius Primo 10.0–15.

Notes on DC Connection General Information about Solar Modules In order to select suitable solar modules and get the most efficient use out of the inverter, please note the following points: The open circuit voltage of the solar modules increases as the temperature decreases (assuming constant irradiance). Note the temperature coefficients in the solar module data sheet.
PV 1 PV 2 DC-2 DC-1 max. 18 A per MPPT DC+2 DC+1 Connect the strings separately to the two MPP Tracker inputs (DC+1/DC+2). The DC- terminals can be used as desired, since they are connected internally. Set MPP TRACKER 2 to "ON" when starting for the first time (also possible in the basic menu subsequently). DC+1 DC+2 DC1 1 2 2 1234 Connecting two solar module fields to a Multi MPP Tracker inverter Single MPP Tracker mode on a Multi MPP Tracker inverter: PV 1 PV 2 max.

The cable cross-section of the DC connecting line and bridging wire must be the same.
Laying Data Communication Cables EN-US Notes on Laying Data Communication Cables IMPORTANT! The inverter must not be operated with one option card and 2 knocked-out option card slots. In this case Fronius provides an appropriate dummy cover as an accessory: 42,0405,2020 ... for Fronius Primo 3.8–8.2 42,0405,2094 ... for Fronius Primo 10.0–15.
Notes on Clipping the Inverter into the Wall Bracket Clipping the Inverter onto the Wall Bracket The side areas of the housing cover are designed to function as carrying grips and/or handles. ON OFF Lock 22.1 lbf.in / 2.5 Nm NOTE! The inverter is fitted with a lock for safety reasons, which allows the inverter to be pivoted in the wall bracket only when the DC main switch is off. Only clip on and pivot the inverter in the wall bracket when the DC main switch is off.
Anti-Theft Device EN-US Notes on Anti-theft device Fronius Primo 3.8–8.2 only An optional anti-theft device is included in the scope of delivery. If required, the anti-theft device is installed before the inverter is screwed to the wall bracket. To ensure that the fixing screws cannot fall out in the inverter's data communications area, these are fitted with a screw release. To remove the fixing screw from the inverter Push the fixing screw upwards from the other side e.g.
1 2 2 max 0.28 in.

USB Stick as a Data Logger and for Updating Inverter Software USB stick as a data logger A USB stick connected to the USB A socket can act as a data logger for an inverter. Logging data saved to the USB stick can at any time be imported into the Fronius Solar.access software via the included FLD file, be viewed directly in third-party applications (e.g., Microsoft® Excel) via the included CSV file. Older Excel versions (up to Excel 2007) have a row limit of 65536.

IMPORTANT! The buffer memory requires a constant power supply. If there is an AC power outage during operation, all data in the buffer memory are lost. The automatic night switch-off must be deactivated so that the data are not lost at night (set "Night Mode" to ON – see chapter "Setting and Displaying Menu Items," section "Displaying and Setting Parameters in the 'DATCOM' Menu Item"). On the Fronius Eco, the buffer memory also functions with just a DC supply.
EN-US Removing the USB Stick Safety information for removing a USB stick X Do not disconnect USB-Stick while LED is flashing! IMPORTANT! To prevent a loss of data, the connected USB stick should only be removed under the following conditions: via the SETUP and "Safely remove USB / hardware" menu items when the "Data Transfer" LED is no longer flashing or illuminated.
Notes on Maintenance Maintenance NOTE! For horizontal installation positions and when installing outside: check once per year that all screws are secured tightly. Maintenance and repair work must only be carried out by authorised personnel. Cleaning 32 The inverter and the display can be cleaned with a damp cloth if necessary. Do not use any cleaning agents, abrasive cleaners, or solvents to clean the inverter.
Serial Number Sticker for Customer Use EN-US Serial Number Sticker for Customer Use The inverter's serial number can be found on the rating plate on the bottom of the inverter. The installation position may make it difficult to access or read the serial number, e.g. if the inverter has been installed in a dark or shaded area. ? Serial No.
