7.3 Installation Method
7.3.1 General
 The module is considered to be in compliance with UL 1703 only when the module is mounted in the manner
specified by the mounting instructions below.
 A module with exposed conductive parts is considered to be in compliance with UL 1703 only when it is electrically
grounded in accordance with the instructions presented below and the requirements of the National Electrical
Code.
 Any module without a frame (laminate) shall not be considered to comply with the requirements of UL 1703 unless
the module is mounted with hardware that has been tested and evaluated with the module under this standard or
by a field Inspection certifying that the installed module complies with the requirements of UL 1703.
 Installation must comply with All local building codes. The Mounting Design must be certified in the USA and
Canada by a registered professional engineer. Also mounting design and procedure shall comply with local codes
and all authorities having jurisdiction.
 Tools used to connect the modules must comply with all applicable electrical safety regulations. They must be dry
and have the correct level of insulation.
7.3.2 Mechanical Mounting Instructions
 Using a torque wrench for installation (Torque to amount specified by professional engineer). Please follow
instructions below for methods of fastening a module to a support structure.
 Modules shall be bolted or clamped to support racking with spans and overhands less than the allowable in the
table below. Any additional mounting outside of these limits without Written Approval from Heliene Inc. will void
the Warranty by doing so.

For Clamping Racking System:
 Each clamp must have a minimum 5mm x 25mm surface clamping onto top surface from the side.
 If the clamps are being used to support two modules (at corner of each), it must have a minimum of 25mm on
each module frame surface.
 Use at minimum 4 clamps to attached modules to the mounting rails.
 Frames must not be deformed by modules clamps, also clamps should not come into contact with the glass.
