Comments
The Scope of UL 2703 is the following:
1.1 These requirements cover rack mounting systems and clamping
devices for flat-plate photovoltaic modules and panels that comply with
the Standard for Flat-Plate Photovoltaic Modules and Panels, UL 1703,
intended for installation on or integral with buildings, or to be
freestanding (i.e., not attached to buildings), in accordance with the
National Electrical Code, ANSI/NFPA 70 and Model Building Codes.
1.2 These requirements cover rack mounting systems and clamping
devices intended for use with photovoltaic module systems with a
maximum system voltage of 1000 V.
1.3 These requirements cover rack mounting systems and clamping
devices pertaining to ground/bonding paths, mechanical strength, and
suitability of materials only.
1.4 These requirements do not cover:
a) Equipment
intended to accept the electrical output from the array, such as power
conditioning units (inverters) and batteries. b) Any tracking mechanism. c) Cell assemblies intended to operate under concentrated sunlight. d) Optical concentrators. e) Combination photovoltaic-thermal modules or panels. f)
Equipment intended to carry current as a normal function of that
component, such as combiner boxes, connection boxes (other than
connection box for grounding), wireways and enclosures housing live
parts. See the Standard for Flat-Plate Photovoltaic Modules and Panels,
UL 1703 or the Standard for Inverters, Converters, Controllers and
Interconnection System Equipment for Use With Distributed Energy
Resources, UL 1741.
