ssembly warnings
Prior to installation, inspect the unit to ensure absence of any transport or handling damage,
which could affect insulation integrity or safety clearances; the failure to do so could result in
safety hazards.
Assemble the inverter per the instructions in this manual. Use care when choosing the
installation location and adhere to specified cooling requirements.
Unauthorized removal of necessary protection features, improper use, incorrect installation
or operation may lead to serious safety and shock hazards and/or equipment damage.

lectrical connection warnings
This grid-tied inverter system operates only when properly connected to the AC utility grid.
Before connecting the inverter to the AC utility grid, contact the local power distribution
company to receive the appropriate approvals. This connection must be made only by
qualified technical personnel.
Wiring methods used should be in accordance with the National Electric Code,
ANSI/NFPA 70 (NEC), Canadian Electric Code (CEC), and/or other local codes
and regulations.
WARNING: To reduce the risk of fire, connect only to a circuit provided with 15A,
20A, or 25A maximum branch circuit overcurrent protection in accordance with the
National Electric Code (ANSI/NFPA 70). See Maximum AC OCPD requirement in
Appendix, section 7.
The inverter should be connected only to a dedicated branch circuit. ABB DOES
NOT provide AC output overcurrent protection; it is the responsibility of the end
user to provide protection for the AC output circuit.
Connect only to a circuit provided with the maximum branch OCPD in accordance
with the CSA document available on the website and listed in the technical data of
the appendix, section 7.
