5 Installation Requirements

For safe operation of the inverter, the installation site must satisfy the following
conditions:
•

Foundation (load carrying capacity)

•

Inverter protection rating / EMC / sound levels

•

Minimum workspace requirements (escape routes)

•

Ventilation / permissible ambient temperature / air quality / humidity

5.1 Installation Site Requirements

5.1.1 Foundation

The foundation must guarantee solid and safe positioning of the inverter. It must provide
the load-carrying capacity necessary to cope with the weight of the inverter. A
foundation slab is required for ground-mounted installations. Pouring and dimensioning
the foundation slab must be performed by the customer, see

Appendix D
