Select the installation location
WARNING!
The TRIO inverter must be installed by qualied 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 modules shaded or isolated.
Environmental 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 specications will result in
power derating. It is recommended the inverter be installed within the specied temperature
range.
• Do not install in direct sunlight. If the preferred mounting location is in direct sunlight, install
the ABB Sun Shield on the inverter in order to provide the necessary shade.
• 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 ow of air around the inverter is not blocked.
• Do not install in places where gases or ammable substances may be present.
