Storage

If you need to store the inverter prior to final installation, note the following points:
Property damage due to dust intrusion and moisture penetration
Dust or moisture intrusion can damage the product and impair its functionality.
• Do not open the enclosure during rainfall or when humidity exceeds the specified thresholds. The humidity
thresholds are: 15% to 95%.
• Only perform maintenance work when the environment is dry and free of dust.
• Operation of the product is only permitted when it is closed.
• Connect the external supply voltage after mounting and installing the product.
• If the installation or commissioning process is interrupted, mount all panels.
• Close and lock the enclosure.
• The product must always be closed for storage.
• Store the product in a dry and covered location.
• The temperature at the storage location must be in the specified range. The temperature range is:
−25°C to +70°C.
Damage to the frame construction of the inverter due to uneven support surface
Placing the inverter on uneven surfaces can cause buckling so that the inverter doors will no longer close properly.
This may lead to moisture and dust penetration into the inverter.
• Never place the inverter on an unstable, uneven surface even for a short period of time.
• The unevenness of the support surface must be less than 0.25%.
• The support surface must be suitable to take the weight of the inverter. Weight: 1800 kg.
• Do not transport the inverter with mounted kick plates.
Desiccant bag in the inverter cabinet
The desiccant bag in the inverter cabinet protects the electronic components from moisture. The desiccant bag
must be replaced by a new desiccant bag included in the scope of delivery one day before commissioning.
