Safety Information All persons installing and servicing inverters must be: • Trained and experienced in general safety rules for work on electrical equipment • Familiar with local requirements, rules and regulations for the installation Safety information important for human safety. Violation of warnings may result in injury to persons or death. Information important for the protection of property.
1. Safety and Conformity Before installation: Check for damage to inverter and packaging. If in doubt, contact the supplier before installing the inverter. Installation: For optimum safety, follow the steps described in this manual. Keep in mind that the inverter has two voltage carrying sides; the PV input and the AC grid. Disconnecting the inverter: Before starting work on the inverter, switch off AC grid at the mains switch and PV using the PV load switch.

3. Installation 3. Installation 3.1. Installation Dimensions and Patterns 3 Note: When choosing the installation place, ensure that all labels are visible at all times. For details refer to the section Specifications. Avoid constant stream of water. Avoid direct sunlight. Ensure adequate air flow. Ensure adequate air flow. Mount on non-flammable surface. Mount upright on vertical surface. Prevent dust and ammonia gases.
3. Installation 3 Illustration 3.1: Safe Distances Observe these distances when installing one or more inverters. One row mounting is recommended. Contact the supplier for information on mounting in more rows. Illustration 3.2: Wall Plate Note: Use of the wall plate delivered with the inverter is mandatory. Use screws that can safely carry the weight of the inverter. The inverter must be aligned and it is important that the inverter is accessible at the front to allow room for servicing.
3. Installation 3.2. Mounting the Inverter For the safe handling of the inverter, two people must carry the unit, or a suitable transport trolley must be used. Safety boots must be worn. 3 Tilt the inverter as shown in the illustration and place the top of the inverter against the mounting bracket. Use the two guides (1) at the top plate to control the inverter horizontally. Illustration 3.
3. Installation Place the lower part of the inverter against the mounting bracket. 3 Illustration 3.5: Place Inverter in Mounting Bracket Lower (4) the inverter and make sure that the hook of the inverter base plate is placed in the lower part of the mounting bracket (5). Check that it is not possible to lift the bottom of the inverter away from the mounting bracket. (6) Fasten the screws on either side of the wall plate to secure the inverter. Illustration 3.6: Fasten screws 3.3.
3. Installation Removal is performed in the reverse order of mounting. With a firm grip at the lower end of the inverter, lift the inverter approximately 20 mm vertically. Pull the inverter slightly away from the wall. Push upwards at an angle until the wall plate releases the inverter. Lift the inverter away from the wall plate. 3 3.4. Opening and Closing the Inverter Remember to observe all ESD safety regulations.
3. Installation Push the front cover upwards. When a slight resistance is felt, give the front cover a tap on the bottom to snap it into holding position. It is recommended to use the holding position instead of dismounting the front cover completely. 3 Illustration 3.8: Open the Inverter To close the inverter, hold on to the lower end of the front cover with one hand and give it a tap on the top until it falls into place. Guide the front cover into place and fasten the two front screws.
3. Installation 3 Illustration 3.10: Fasten Front Screws and Ensure Proper PE Connection. The two front screws are the PE connection to the front cover. Make sure that both screws are mounted and fastened with the specified torque. 3.5. AC Grid Connection Note: When choosing the installation place, ensure that all labels are visible at all times. For details refer to the section Specifications.
3. Installation 3 Illustration 3.11: AC Cable Wire Strip Legend 1 Blue cable - Neutral 2 Yellow/green cable - Earth The illustration shows the stripping of insulation of all 5 wires of the AC cable. The length of the PE wire must be longer than the mains and neutral wires. Illustration 3.12: AC Connection Area 1. Verify the inverter matches the grid-voltage 2. Release main circuit breaker and make precautions to prevent reconnection. 3. Open the front cover. 4.
3. Installation 3 6. The Protective Earth wire (PE) is mandatory and must be connected directly to the chassis PE terminal. Insert the wire and fasten the screw to secure the wire. 7. All wires must be properly fastened with the correct torque. See the section Technical Data, Torque Specifications for Installation. 8. Close the front cover, and remember to verify that both front screws are applied with the correct torque to obtain PE connection. 9. Close main circuit breaker.
3. Installation When unmated the MC4 connectors are not IP54. The intrusion of moisture may occur in the following situations: 1. The inverter runs in Master/Slave operation and only one or two PV inputs are in use. In this case, the other inputs are not connected to PV and they are therefore open to intrusion. 2. Not all PV inputs are connected. 3. PV connectors are not fitted; for example in case of disconnection of parts of a PV plant over a longer period of time.
4. Start-up and Check of Settings 4. Start-up and Check of Settings 4.1. Start-up and Check of Settings Note: Due to the advanced functionalities of the inverter, it may take up to 10 seconds before the display becomes available after power up. 4 Note: For the version the first start-up and check of settings can also be performed via the integrated Web Server. For further details, refer to the Web Server User Manual. The inverter is shipped with a predefined set of settings for different countries.
4. Start-up and Check of Settings Set time as prompted by the display. Press 'OK' to select number. Press ‘ ▲ ’ to scroll up through the numbers. Select by pressing 'OK'. The clock is 24-hour format. 4 Illustration 4.2: Set Time Note: It is very important to set the time and date accurately as the inverter uses this for logging. If a wrong time/date is accidentally set, correct it immediately in the set date and time menu [Setup → Inverter details → Set date and time].
4. Start-up and Check of Settings Enter the amount of installed PV power for each of the PV inputs. When two or more PV inputs are connected in parallel, each PV input in the parallel group must be set to the total amount of PV power installed to that group divided by the number of parallel inputs. See the table below for examples of installed PV power. 4 Illustration 4.4: Installed PV Power The display will now show “Select country”. The country is set to “undefined” at initial start-up.
4. Start-up and Check of Settings Note: If the two country selections do not match they will be cancelled and it will be necessary to redo the selections. If a wrong country is accidentally accepted at the first selection, simply accept the “Country: Undefined” in the confirm country screen. This will cancel the country selection and a new selection is possible. If a wrong country is selected twice, call service. The inverter will start automatically if sufficient solar radiation is available.
4. Start-up and Check of Settings of larger networks. Replication can be performed once, prior to defining the country setting in follower inverters. To enable Master mode go to the Inverter details menu [Setup → Inverter details → Master mode] and set Master mode to Enabled. Ensure that no other master inverters are present in the network prior to carrying out this action. When Master mode is enabled, it is possible to initiate a network scan [Setup → Inverter details → Master mode → Network].
