This guide contains information regarding the installation and safe handling of ET
Solar photovoltaic modules (hereafter referred to as "modules"). All instructions should
be read and understood before attempting installation. If there are any questions,
please contact your dealer or ET Solar for further information. The installer should
conform to all safety precautions in the guide when installing modules. Before
installing a solar photovoltaic system, the installer should become familiar with the
mechanical and electrical requirements for photovoltaic systems. Keep this guide in
a safe place for future reference. If not otherwise specified, it is recommended that
the requirements of the U.S. National Electrical Code (NEC) or respective European
Code be followed.
Non-compliance with this installation instruction may result in property damage
and/or physical injury. ET Solar will not be liable for compensation of any loss or injury
caused by this type of non-compliance.

TABLE OF CONTENTS
1. PURPOSE OF THIS GUIDE
Installing solar photovoltaic systems requires specialized skills and knowledge. The
installer assumes all risk of injury, including risk of electric shock. Module installation
should be performed only by qualified persons.
All modules come with a permanently attached junction box and #12 AWG (4 mm²)
wire terminated in Multi Contact PV connectors. Your dealer can provide additional
extension cables to simplify module wiring.
Each individual module can generate DC voltages greater than 30 volts (V) when
exposed to direct sunlight. Contact with a DC voltage of 30 V or more is potentially
hazardous. Exercise caution when wiring or handling modules exposed to sunlight.
When disconnecting wires connected to a photovoltaic module that is exposed to
sunlight, an electric arc may occur. Arcs can cause burns, start fires or otherwise
create safety problems. Exercise caution when disconnecting wiring on modules
exposed to sunlight.
