1- Introduction and safety
General installation warnings
The ABB transformerless inverter is designed and tested according to international safety
requirements (UL1741/IEEE1547); however, certain safety precautions must be observed
when installing and operating this inverter. Read and follow all instructions, cautions and
warnings in this installation manual.
All operations regarding transport, installation start up, and maintenance, must be carried out
by qualied, trained personnel and in compliance with all prevailing local codes and regula-
tions.
Assembly 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 specied 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.
Electrical 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
qualied 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 re, 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.

1- Introduction and safety
Safety instructions
These servicing instructions are for use by qualied personnel only. To reduce the risk of electric shock, do not
perform any servicing other than that specied in the operating instructions. Be sure all ammable materials
including construction items are away from the unit. Do not install the inverter in or near potentially explosive
areas.
The inverter is designed without an isolation transformer and is intended to be installed per NFPA 70, 690.35
with an ungrounded PV array. These models have no grounded input conductors.
General information
The equipment has been manufactured in accordance with the strictest accident-prevention
regulations and supplied with safety devices suitable for the protection of components and
operators. Inform ABB about non-standard installation conditions.
It is essential to provide operators with correct information. They must read and comply with
the technical information given in the manual and any other attached documentation. The
instructions given in the manual do not replace the information and warnings on the
safety labels mounted on the product. They do not replace the safety regulations enforced
in the country of installation.
Maintenance operations must be carried out according to the maintenance section 6 of this
manual. Do not use the equipment if any operating anomalies are found. Liabilities arising
from commercial components are delegated to their respective manufacturers.
Thermal and voltage hazard
WARNING: Depending upon ambient temperatures during operation and
immediately following shut down, surface temperatures on the cooling ns (heat
sink) and some areas of the chassis may be extremely hot to the touch.
Prior to touching any part of the inverter use care to ensure surfaces and equipment are at
touch-safe temperatures and voltages before proceeding.
The customer and/or installer must appropriately instruct all personnel who may come
near the equipment, and highlight, if necessary with notices or other means, the hazardous
areas or operations: magnetic elds, hazardous voltages, high temperatures, possibility of
discharges, generic hazard, etc.
Anytime the inverter has been disconnected from the AC utility grid, use extreme caution
as some components can retain charge sufcient to create a shock hazard and may need
time to dissipate the charge. To minimize occurrence of such conditions, comply with all
corresponding safety symbols and markings present on the unit and in this manual.

1- Introduction and safety
Clothing and protective devices
Appropriate Personal Protective Equipment (PPE) must be worn at all times when servicing
this equipment under any conditions which may subject personnel to hazardous voltages or
temperatures that are not touch-safe.
All operations on the equipment should be performed with properly electrically insulated
instruments.
Location of safety notices and labels
Note the location of safety notices on the inverter for notication and protection. Labels must
not be hidden with external objects or parts such as rags, boxes, or other such equipment.
They should be cleaned periodically and always maintained in view.
Appropriate usage
The inverter is a photovoltaic inverter that converts direct current of a connected PV array into alternating
current and feeds that power into the AC utility grid. This inverter is designed for outdoor use, but can be used
indoors if installed to specied environmental and mounting parameters stated in this manual, and adherence
to the National Electric Code. (See environmental conditions below and environmental checks in section 2.)
Conditions of Use
WARNING! This inverter utilizes a transformerless design and requires connect-
ed array(s) to be oating with respect to ground; it can be used only with photovol-
taic modules that do not require one of the terminals to be grounded.
• The DC and AC operating currents MUST NOT exceed the limits documented in the
technical specications.
• The inverter is certied for use only with photovoltaic arrays connected to its input
channel(s). Do not connect batteries or other types of power sources.
• The inverter can only be used if all the technical requirements in this manual are observed
and applied.
Environmental conditions
Adverse environmental conditions can lead to a reduction in performance. The equipment
should be installed outdoors, but only in environmental conditions indicated in this manual.
Care must be taken to provide adequate ventilation if installed indoors.
Improper or prohibited use
The following actions are dangerous and not consistent with acceptable practice under the
terms of the warranty:
