5.1 Selecting the Mounting Location

Requirements for the mounting location:
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the inverter in areas where highly flammable materials are stored.
• Do not mount the inverter in areas having a potentially explosive atmosphere
The inverter can become hot during operation
Touching the enclosure can result in burn injuries.
• Install the inverter in such a way that it cannot be touched accidentally.
☐ The inverter must be mounted to a solid building ground (e.g., concrete or block wall) or on
drywall to a beam or stud.
☐ In living areas, make sure that the building ground is not made of plasterboard or similar.
When in operation, the inverter makes noises which can be perceived as a nuisance.
☐ The mounting location must be suitable for the weight and dimensions of the inverter with
DC Disconnect (see Section 13 "Technical Data", page 77).
☐ The mounting location must not be exposed to direct sources of water spray such as sprinklers
or gutters.
☐ Climatic conditions must be met (see Section 13 "Technical Data", page 77).
☐ The mounting location should be freely and safely accessible at all times without the necessity
for any auxiliary equipment, such as scaffolding or lifting platforms. Non-fulfillment of these
criteria may restrict servicing.
☐ The mounting location should not be exposed to direct solar irradiation. Direct solar irradiation
can increase the operating temperature of the inverter. As a result, the inverter reduces its power
output in order to remain within the operating limits.
☐ To ensure optimal operation, the ambient temperature must be below 104°F (40°C).
The inverter can, however, be operated at higher ambient temperatures without risk in the event
of any possible reductions in output power.
