Important Safety Information
WARNING!
Incorrect operation or poorly executed work can cause serious injury or damage. Installation and commissioning must be carried out by trained personnel in accordance with nationally applicable standards and guidelines. Ensure all provided documents are read and understood before working with the device. PV modules exposed to light supply voltage to the inverter. This document does not describe all possible system configurations.
FR: AVERTISSEMENT!
Les erreurs de manipulation et les erreurs en cours d'opération peuvent entraîner des dommages corporels et matériels graves. L'installation et la mise en service ne doivent être effectuées que par du personnel formé et conformément aux normes et directives nationales en vigueur. Ne travailler avec l'appareil que lorsque tous les documents mis à disposition en annexe ou en ligne ont été lus et compris! Les modules solaires recevant de la lumière fournissent de la tension à l'onduleur. Ce document ne décrit pas toutes les configurations système possibles.
DE: WARNUNG!
Fehlbedienung und fehlerhaft durchgeführte Arbeiten können schwerwiegende Personen- oder Sachschäden verursachen. Die Installation und Inbetriebnahme darf nur durch geschultes Personal und gemäß den national gültigen Normen und Richtlinien erfolgen. Vor Arbeiten mit dem Gerät, alle beiliegenden, aufgedruckten und online zur Verfügung gestellten Dokumente lesen und verstehen! PV-Module, die Licht ausgesetzt sind, liefern Spannung an den Wechselrichter. Dieses Dokument beschreibt nicht alle möglichen Systemkonfigurationen.
IT: AVVISO!
L'esecuzione errata degli interventi può causare gravi lesioni personali e danni materiali. L'installazione e la messa in funzione del sistema deve essere eseguita esclusivamente da personale qualificato e conformemente alle norme e direttive in vigore nel luogo di installazione. Prima di lavorare con l'apparecchio, leggere e comprendere tutta la documentazione acclusa con esso e disponibile online! I moduli solari esposti alla luce erogano tensione all'inverter.

Connecting the Data Communication
6. Data Communication Connection
Diagram: Shows an 8 mm (0.31 in.) connection point and a table detailing Smart Meter connections (Pin M-, M+, GND, V+/GND) to various terminals (33, 34, 35, 11, 12, 13, 9, 10, 5, 6, 4) for different Smart Meter models (50k A-3, 63A-1, 63A-3, TS 5kA-2, TS 5kA-3, TS 100A-1).
Connect data communication using 8 mm (0.31 in.) terminals. Refer to the table for specific Smart Meter model connections.
7. Wiring Diagram
Diagram: Shows a wiring diagram connecting the Smart Meter to the Inverter with specific pins (M+, M-, WSD IN-, WSD IN+, GND, V+).
Follow the provided wiring diagram to connect the Smart Meter to the Inverter.
Mounting the Protective Cover
8. Protective Cover Mounting
Diagram: Shows mounting the protective cover using 5x B 2.2 x 6.5 mm screws with a torque of 0.2 Nm (0.14 ft-lb).
Mount the protective cover using 5 screws (B 2.2 x 6.5 mm) with a torque of 0.2 Nm (0.14 ft-lb).
Commissioning
9. Commissioning Steps
Diagram: Shows a switch labeled 'AC~ OFF' and 'ON', with a battery symbol indicating 'Battery ON'. Torque specification of 0.75 Nm (0.55 ft-lb) for TX10 / M5 x 9 mm screws is shown.
Step 1: Turn the switch to 'ON'.
Step 2: Ensure 'Battery ON' is selected.
Step 3: Tighten TX10 / M5 x 9 mm screws to 0.75 Nm (0.55 ft-lb).
Note: Be aware of DC Voltage.
User Interface Configuration
10. Configuring Backup Power
Diagram: Shows the inverter's user interface with options for 'Device Configuration' and 'Functions and I/Os'. A table lists 'V+/GND' and 'I/O' with corresponding numbers.
Step 1: Open the user interface of the inverter.
Step 2: Navigate to Device Configuration > Functions and I/Os.
Step 3: Activate Backup Power.
Step 4: Select 'Full Backup' under Backup Power Mode.
Testing the Backup Power Function
11. Backup Power Test
Diagram: Shows the 'Backup Switch' in 'OFF' and 'Backup power supply' states.
Test the backup power function by observing the switch states during grid supply and backup power supply.
