(United States and Canada)
1.0
Introduction
This manual provides safety and installation instructions for UL Listed
SunPower photovoltaic (PV) modules that have the UL logo on the
product label:
1.1 Disclaimer of Liability
The installation techniques, handling, and use of this product are beyond
company control. Therefore, SunPower assumes no responsibility for loss,
damage or expense resulting from improper installation, handling, or use.
1.2 Underwriters Laboratories (UL) Listing Information
This product meets or exceeds the requirements set forth by UL 1703 and
ULC/ORD-C1703-01 for PV Modules. These Standards cover flat-plate PV modules
and panels intended for installation on buildings or those intended to be
freestanding. To satisfy the Listing for this product the modules must be mounted
with a rack or standoff structure. The Listing does not include integration into a
building surface because additional requirements may apply. This product is not
intended for use where artificially concentrated sunlight is applied to the module.
1.3 Limited Warranty
Module limited warranties are described in full in the SunPower warranty
certificates obtainable at
www.sunpower.com
. In summary, the Limited
Warranties do not apply to any of the following:
Modules which in SunPower's absolute judgment have been subjected to misuse,
abuse, neglect or accident; alteration; or improper installation, application or
removal. This includes, but is not limited to, installation, application, or removal
by any party other than a SunPower authorized dealer; non-observance of
SunPower's installation, user’s and/or maintenance instructions; repair or
modifications by someone other than an approved service technician of
SunPower; power failure surges, lightning, flood, fire, accidental breakage, or
other events beyond SunPower's control.

Safety Precautions
Before installing this product, read all safety instructions in this document.
All installations must be performed in compliance with the National Electrical
Code (NEC) and any applicable local codes.
For Canadian jurisdictions, installations shall be in accordance with CSA C22.1,
Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1
There are no user-serviceable parts within the module. Do not attempt to
repair any part of the module.
Installation should be performed only by qualified personnel.
Do not stand on, drop, scratch, or allow objects to fall on modules as it may
damage and void the warranty.
Do not place anything on the modules, even for a moment because resulting
residue may damage or stain the glass surface.
If the front glass is broken, or the backsheet is torn, contact with any module
surface or module frame can cause electric shock.
Broken J-boxes or connectors are electrical hazards as well as laceration
hazards. Installers should remove any such module from the array and
contact SunPower for disposal instructions.
Do not install or handle the modules when they are wet or during periods of
high wind.
SunPower recommends a conservative minimum cable bend radius of equal
to or greater than
40 mm (1.5”).
Contact SunPower if maintenance is necessary.

2.1 Fire Rating
The module fire rating is Type 2 per UL1703, 2013 edition and Class C per
UL1703, 2002 edition. Fire rating classification for any PV system using
UL1703:2013 can only establish a fire rating in combination with the mounting
system ratings normally found in the mounting system installation instructions.

For all models the Maximum System voltage for IEC standards is 1000V and
maximum series fuse is 15A. For models not shown here, please contact SunPower
technical support or visit
www.sunpower.com
. Electrical parameters are measured at
Standard Test Conditions (STC).
DANGER!
Module interconnection cables pass direct current (dc) and
are sources of voltage when the module is under load and when it is
exposed to light.
Direct current can arc across gaps and may cause
injury or death if improper connection or disconnection is made; or
if contact is made with module leads that are frayed or torn.
Do not
connect or disconnect modules when a current source is energizing
the conductors. Modules may contain high voltage when
interconnected with other modules.
IMPORTANT!
Please read this manual in its entirety before
installing, wiring, or using this product in any way. Failure to comply
with these instructions will invalidate the SunPower Limited
Warranty for PV Modules.
