IMPORTANT SAFETY INSTRUCTIONS

Keep the manual for future reference.
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As
with all electrical or electronical devices, there are residual risks despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
Danger to life due to electric shock when live components or cables of the
inverter are touched
High voltages are present in the conductive components or cables of the inverter. Touching live
parts and cables of the inverter results in death or lethal injuries due to electric shock.
• Disconnect the inverter from voltage sources and make sure it cannot be reconnected
before working on the device.
• Wear suitable personal protective equipment for all work on the product.
Danger to life due to electric shock from touching an ungrounded product in
the event of an error
A product that is not grounded may be energized in the event of an error. Touching an
ungrounded product results in death or serious injury due to electric shock in the event of an
error.
• Ensure that the product is integrated in the existing surge protection.
Increased electromagnetic radiation through the antenna
During operation, the antenna produces an electromagnetic field and can interfere with other
devices (e.g., pacemakers) due to electromagnetic interference.
• Persons must not remain closer than 20 cm to the antenna for long periods of time.
Damage to the enclosure seal in subfreezing conditions
If you open the inverter when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the inverter if the ambient temperature is not below -5°C.
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the inverter (e.g. by melting the ice with warm air).
