Damage to the inverter due to moisture penetration
If the inverter is not stored properly, moisture can penetrate the enclosure and cause damage to electronic components.
• Only store the inverter in its closed state.
• Storage for six months or more permissible in dry locations only.
• Store at a temperature between ‒13°F and +140°F ( − 25°C to +60°C).

Damage to the inverter due to uneven building ground
Storing the inverter on an unsuitable building ground could damage the frame construction. Dust and moisture can
penetrate the inverter and damage electronic components.
• The building ground must be suitable for the weight of the inverter of 4,123 lbs. (1,870 kg).
• The unevenness of the building ground must not exceed 0.25%.
Storage in cold temperatures and high humidity
If, when storing the device, you connect the external voltage supply and switch on the circuit breaker of the external
voltage supply as well as the circuit breakers of the 24 V circuits, the heater is activated automatically in the event
of high humidity. As a result, you prevent condensation water from forming. The connection of the external voltage
supply is described in Section 12.8.
