nstallation site and position
- Consult technical data to confirm the environmental specifications will be met
- Installation of the unit in a location exposed to direct sunlight must be
avoided (otherwise the warranty will be voided) as it may cause:
- power limitation phenomena in the inverter (with a resulting de-
creased energy production by the system)
- premature wear of the electrical/electromechanical components
- premature wear of the mechanical components (gaskets) and of the
user interface (display)
- Do not install in closed spaces where air does not freely circulate
- Do not install in spaces inhabited by people or animals due to the po-
tential audible noise level of an operating inverter.
- Always ensure that the airflow around the inverter is not restricted or
blocked, so as to prevent overheating.
- Do not install the equipment near flammable substances
- Do not install the equipment on wooden walls or supports, or other
flammable substances.
- Maintain minimum clearance from objects blocking air circulation and
maintain minimum spacing between inverter as indicated in the figures.
- Maintenance on device hardware and software entails removing the
front covers. Check that the correct installation safety distances are ob-
served in order to allow routine check and maintenance operations.
- Install on a wall or strong structure capable of bearing the weight
- Ensure sufficient working area in front of the inverter for wiring box access
- If possible, install at eye level so that the display and LEDs can be
easily seen
- Install at a height that takes account of the weight of the equipment
- All installations over 6500' (2,000 meters) must be assessed by ABB
