Intended Use; Limitations In Intended Use; Improper Or Prohibited Use - ABB UNO-DM-TL-PLUS-US Product Manual

I
ntended use
Do not use the inverter in a way for which is was not intended. The inverter MUST NOT be
used by inexperienced staff, or even experienced staff if carrying out operations that fail to
comply with the iinstuctions in this product manuals, or documentation shipped with the inverter.
L
imitations in intended use
The inverter is designed for use with photovoltaic modules which have floating inputs.
Only photovoltaic modules may be connected to the inverter input. Do not connect batteries
or other power supplies.
The inverter cannot be connected, on the DC side, in parallel to other inverters to convert
energy from a photovoltaic array with power exceeding the nominal power of the single
inverter.
The inverter may only be used in compliance with all its technical specifications.
I
mproper or prohibited use
DO NOT:
• Install the inverter in environments subject to flammability or in adverse or disallowed
environmental conditions, (temperature and humidity).
• Use the inverter with safety devices which are faulty or disabled.
• Use the inverter or part of it connected to other machines or equipment.
• Modify operating parameters that are not accessible to the operator, or modify the inverter
to chance its performance or electrical isolation.
• Clean with corrosive products that could damage the inverter.
• Use or install the inverter or parts of it without having read and understood the contents of
the product manual.
• Heat or dry rags, or clothing, on inverter. In addition to being hazardous, it would compromise
component ventilation and cooling.
ABB is not be liable for any damage whatsoever that may result from
incorrect or careless operation.
The inverter is designed for
transforming continuous electrical current (DC)
supplied by photovoltaic array (PV)
into alternating electrical current (AC)
suitable for feeding to the public distribution grid.
