Danger due to ground fault on DC side during
operation
Due to the transform erless topology of the product, the
occurrence of ground faults on DC side during operation
can lead to irreparable damage. Damages to the product
due to a faulty or damaged DC installation are not
covered by warranty. The product is equipped with a
protective device that checks whether a ground fault is
present during the starting sequence. The product is not
protected during operation.
• Ensure that the DC installation is carried out correctly
and no ground fault occurs during operation.
The inverter is not equipped with a transformer and is
intended to be installed with an ungrounded (floating) PV
array.
Input and output circuits are isolated from the enclosure.
System grounding is the responsibility of the installer.
All persons responsible for the installation and
maintenance of inverters must be:
• Trained and authorized in general safety rules for
work on electric equipment.
• Familiar with local requirements, rules and
regulations for the installation.
The inverter does not provide overcurrent protection. This
must be provided by the installer. See table 5.8
The temperature of the cooling elements and components
in the inverter can exceed 70°C. There is a risk of burns.
The inverter is to be installed in such way that hot
components cannot be touched.
Installation Guide
Damage to the product due to outgassing of
sealants
Sealants such as silicone, polyurethane foam or sealing
foam can outgas. Outgassing of sealants can damage the
product and impair its functionality.
• Do not use any sealants for sealing.
• Only use the provided material for sealing.

Symbols on the inverter
Symbol Explanation
Danger to life due to electric shock
The product operates at high voltages.
All work on the product must be
carried out by qualified persons only.
Danger
This symbol indicates that the inverter
must be additionally grounded if
additional grounding or equipotential
bonding is required at the installation
site.
Danger to life due to high voltages in
the inverter; observe waiting time.
High voltages that can cause lethal
electric shocks are present in the live
components of the inverter.
Prior to performing any work on the
inverter, disconnect it from all voltage
sources as described in this document.
