Mounting
!
Physically damaged modules may cause ground faults and associated electrical hazards. To avoid these conditions:
!
Do not install the modules during high wind or wet conditions to reduce the likelihood of injury.
Wear safety glasses (ANSI Z87.1-2003) and cut-resistant gloves when working on non-interconnected modules or
!
systems.
!
Wear electrically rated PPE when working on interconnected modules or system components.
•
Handle modules with care during installation, as heavy impact on the front, back, or edges could result in damage
to the module. Do not walk or stand on modules or retaining clips.
•
Do not stack or carry multiple modules on top of one another after removal from factory packaging to minimize
the risk of breakage.
•
Do not lift or pull on modules using lead wires or strain relief wire loops to minimize the risk of wire damage.
Mounting of the Series 4 and Series 4A Module to a suitable structure can be done by attaching the module directly to the
structure using retaining clips (see Figure 5.1).
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. The Series 4 and Series 4A Module
is a frameless laminate and is considered to be in compliance with UL 1703 only when the module is mounted using approved
hardware in the manner specified by the mounting instructions in Chosen Techno Solar Private Limited Application Note PD-5-
320-04 NA.
Additional mounting systems may be approved for use. The interface of the mounting structure to the module (including the
retaining clip and rubber insulator) must meet the technical requirements specified in Chosen Techno Solar Private Limited
Application Note PD-5-320-04 and must be approved for use by Chosen Techno Solar Private Limited prior to installation. The
mounting system design must provide adequate support for the module to prevent damage from occurring when the module is
subjected to pressures of 2400Pa (which equates to wind pressure of 130km/h (80.8 mph), with a safety factor of 3 for gusty
conditions based on IEC 61646 / IEC 61215). The location of the clips shall be along the 1200mm (47.25 in) length of the module
and the center point of the clip shall be located between 250mm (9.84 in) and 300mm (11.81 in) from the module edge. See
Figure 5.1 for allowed location. Rubber insulator material, or equivalent must be used between the module and both the clip
and mounting structure to provide adequate protection of the module and must meet all requirements described in PD-5-320-
04 Module Mounting. No direct contact of rigid structures is permitted against the surface or edges of the module.
All mounting structures must provide a flat plane for the modules to be mounted on, and must not cause any twist or stress to
be placed on the module.
Modules should not be installed in a way that restricts air circulation to the underside of the module. Modules generate
heat and require adequate airflow for cooling.
