elect the installation location
WARNING! The inverter must be installed by qualified installers and/or licensed electricians
according to the applicable local code regulations (NEC, CEC, and other).
Once physically mounted, the wiring must be carried out with the equipment disconnected from the
grid (power disconnect switch open) and the photovoltaic panels shaded or isolated.
E
nvironmental check
• See technical data in the appendix, section 7, to check the environmental parameters to
be observed (degree of protection, temperature, humidity, altitude, etc.).
• The maximum operational ambient air temperature MUST be considered when choosing
the inverter installation location.
• Installing the inverter where operating temperatures exceed the specifications will
result in power limiting. It is recommended the inverter be installed within the specified
temperature range.
• Exposure to direct sunlight will increase the operational temperature of the inverter and
may cause output power limiting. ABB recommends using a sun shade minimizing direct
sunlight when the ambient air temperature around the unit exceeds 104°F/40°C.
• Do not install in small closed spaces where air cannot circulate freely.
• Due to acoustical noise (about 50dBA at 1 m) from the inverter, do not install in rooms
where people live or where the prolonged presence of people or animals is expected.
• To avoid overheating, always make sure the flow of air around the inverter is not blocked.
• Do not install in places where gases or flammable substances may be present.
Direct sunlight use caution
Air flow restricted use caution
