1. When designing the PV system, please always take into consideration the variation of the voltage under different
temperatures (please check the respective temperature coefficient specifications of the modules, the Voc of the modules
will rise when the temperature drops);
2. Trina Solar requires that every DUOMAX series PV module string should be fused prior to be connected with other
strings. For the maximum fuse rate, please refer to the detailed SPEC in the last page.
3. Solar photovoltaic (PV) modules generate electricity when exposed to light. An array of many such modules can cause
lethal shocks and/or burn hazards. Only authorized and trained personnel should have access to the modules.
4. Use properly insulated tools and appropriate protective equipment to reduce risk of electric shock.
5. Do not stand or step on the module.
6. Do not damage or scratch the front or backside surfaces of the module.
7. Never use a module with broken glass or top substrate. Broken modules should not be repaired and contact with any
module surface can lead to electrical shock.
8. Do not disassemble the modules or remove any part of the module.
9. Protect plug contacts against soiling and do not make any plug connections using soiled plug contacts.
10. Do not install or handle modules when they are wet or during periods of high wind.
11. Do not connect cable from the positive terminal to the positive terminal of one single PV module.
12. Make sure connectors have no gap between insulators. A gap can cause fire hazard and/or danger of an electrical
shock.
13. Make sure that the polarity of each module or a string is not reversed relative to the other the modules or strings
14. Artificially concentrated sunlight should not be used on the PV module.
15. In markets conforming to IEC standard, maximum system voltage must not exceed 1500V DC. In markets conforming
to UL standard, maximum system voltage must not exceed 1000V DC. For roof use, the maximum system voltage
must not exceed 600V according to National Electrical Code.
16. Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or
voltage than reported at standard test conditions. The requirements of the National Electrical Code (NEC) in Article
690 shall be followed to address these increased outputs. In installations not under the requirements of the NEC, the
values of ISC and VOC marked on this module should be multiplied by a factor of 1.25 when determining component
voltage ratings, conductor ampacities, over-current device ratings, and size of controls connected to the PV output.
17. Our module application class is class A, modules rated for use in this application class may be used in systems
operating at greater than 50V DC or 320W, where general contact access is anticipated..
18. Installation shall be in accordance with CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical
Code, Part 1.
19. 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.
20. The DUOMAX modules have achieved fire rating Type 13 according UL1703 updated on 20th May 2014. The fire
rating of this module is valid only when mounted as specified in the mechanical mounting instructions in this
document.
21. The actual system fire rating should always be evaluated along with the roof cover and mounting.
22. 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.
3. UNPACKING AND STORAGE
1. Before installation, keep all modules and electrical contacts clean and dry.
2. If it is necessary to store modules temporarily, a dry, ventilated room should be used.
3. When unpacking, carry modules with both hands. Do not place modules on top of each other.
4. The double glass module should be handled carefully, so non-slip gloves are required for handling and installation.
5. Please use the appropriate removal tools when dismantling the plywood cases.

Trina suggests using M8 bolts to fix the clamp. The torque for M8 screw is 16-20 N*M.
When choosing the bolts and T-shape nuts for the clamp, please note your racing’s dimensions first.
For C structure steel type 1 racking, due to the amount of space inside the racking section, many choices are
available including T-shape nuts.
*NOTE: Please consult with a Trina Solar engineer before installing with the frameless clamps
PV modules can be mounted to the substructure using either corrosion-proof M8 bolts placed through the
mounting holes on the rear of the module or specially designed module clamps.
Regardless of the fixing method the final installation of the modules must ensure that:
•A clearance of at least 115mm(4.5in) (recommended) is provided between modules frame and the surface
of the wall or roof. If other mounting means are employed this may affect the UL Listing or the fire class
ratings.
•The minimum distance between two modules is 10mm(0.4in).
•The mounting method does not block the module drainage holes.
•Panels are not subjected to static loads exceeding the maximum permissible loads, and are not subject to
excessive forces due to the thermal expansion of the support structures.
*NOTE: The drain holes cannot be blocked in any situation during installation or use.
A. Mounting with Bolts
•The frame of each module has 4-φ9*14mm mounting holes, ideally placed to optimize the load
handling capability, to secure the modules to supporting structure.
•To maximize mounting longevity, Trina Solar strongly recommends the use of corrosion proof
(stainless steel) fixings
•Secure the module in each fixing location with an M8 bolt and a flat washer, spring washer and nut as
shown in Figure 1 and tighten to a torque of 16~20 N.m(140-180lbf.in.).
•All parts in contact with the frame should use flat stainless steel washers of minimum 1.8mm thickness
with an outer diameter of 20-24mm(0.79-0.94in).

3)Flat Stainless Washer 4)Spring Stainless Washer
5) HEX Stainless Nut
B. Mounting with Clamps
•Trina Solar has tested its modules with a number of clamps from different manufacturers and
recommends the use of clamps which have an EPDM or similar insulating washer, fixing bolt of at
least M8. The length of clamp ≥40mm(1.57in).
•The clamp must overlap the module frame by at least 7mm (0.28in) but no more than 10mm (0.39in).
•Use at minimum 4 clamps to fix modules on the mounting rails.
•Modules clamps should not come into contact with the front glass and must not deform the frame.
•Be sure to avoid shadowing effects from the module clamps.
•The module frame is not to be modified under any circumstances.
•When choosing this type of clamp-mounting method, use at least four clamps on each module, two
clamps should be attached on each long sides of the module (for portrait orientation) or each short
sides of the module (for landscape orientation). Depending on local wind and snow loads, additional
clamps may be required to ensure that modules can bear the load.
•Applied torque should refer to mechanical design standard according to the bolt customer is using, ex:
•M8 ---- 16-20N.m(140-180lbf.in)

6.3 GROUNDING
Grounding of the modules (Grounding bolts: GB845-85-ST4.2*13-F-H: )
Star washer, flat washer,
grounding wire are placed in
turn, then screwed into the
grounding hole to bond the
adjacent modules
•All module frames and mounting racks must be properly grounded in accordance with appropriate respective
National Electrical Code.
•Proper grounding is achieved by bonding the module frame(s) and all metallic structural members together
continuously using a suitable grounding conductor. The grounding conductor or strap may be copper, copper
alloy, or any other material acceptable for use as an electrical conductor per respective National Electrical
Codes. The grounding conductor must then make a connection to earth using a suitable earth ground electrode.
•Trina Solar modules can be installed with the use of third party listed grounding devices for grounding the
metallic frames of PV modules. The devices have to be installed in accordance with the grounding device
manufacturer’s specified instructions.
•Please refer to the “Product Catalogue” link for detailed grounding hole locations and size at
http://www.trinasolar.com/
•Grounding hardware comes in a package that includes the grounding screw, flat washer、star washer and wire
•Electrical contact is made by penetrating the anodized coating of the aluminum frame, and tightening the
mounting screw (come with the star washer) to the proper torque of 25lbf.in.
•Grounding wire size (6 to 12 AWG solid bare copper) should be selected and installed underneath the wire
binding bolt.

6.4 INSTALL EFFECT CHART
The install effect chart is as follows. Please consult with Trina Solar engineers to confirm whether the rails match Trina
clamp/frame or not. And confirm there are no shelter on the back of the modules.
7. MODULE WIRING
Each module has two 4mm2 diameter type standard 90°C sunlight resistant output cables each terminated with plug & play
connectors. This cable is suitable for applications where wiring is exposed to the direct rays of the sun. We recommend that
all wiring and electrical connections comply with the appropriate national electrical code(s).
For field connections, use the minimum 4mm2diameter copper wires insulated for a minimum of 90°C and sunlight
resistant as well.
The minimum and maximum outer diameters of the cable are 5mm to 7mm. Refer to Datasheet Specifications for the
maximum electrical rating of series fuse.
8. MODULE TILT ANGLE
Trina Solar PV modules connected in series should be installed at the same orientation and angle. Different orientation or
angle may cause loss of output power because each module may be exposed to different amounts of solar irradiation.
Trina Solar PV modules produce the most power when they are perpendicular to incoming sunlight. For installations where
the PV modules are attached to a permanent structure, the PV modules should be tilted for optimum winter performance.
The module tilt angle is measured between the solar modules and the ground. Optimal tilting of PV module is almost the
same as the latitude of installation location.

9. MAINTENANCE AND CARE
•Under most weather conditions, normal rainfall is sufficient to keep the PV module glass surface clean. If dust or dirt
build-up becomes excessive, clean the glass only with a soft cloth using mild detergent and water.
•Do not clean the modules with cold water during the warmer hours of the day in order to avoid creating any thermal
shock that may damage the module.
•At least once a year, it is recommended to check the torque of terminal screws and the general condition of wiring.
Also, check that mounting hardware is properly torqued. Loose connections will result in damage of the array.
•Modules that are replaced must be the same type. Do not touch live parts of cables and connectors. Use appropriate
safety equipment (insulated tools, insulating gloves, etc.) when handling modules.
•Cover the front surface of modules by an opaque material when repairing. Modules when exposed to sunlight generate
high voltage and are dangerous.
•Trina Solar PV modules are equipped with bypass diodes in the junction box. This minimizes module heating and
current losses.
Do not try to open the junction box to change the diodes even if they malfunction.
In a system using a battery, blocking diodes are typically placed between the battery and the PV module output
to prevent battery discharge at night.
Trina Solar is a member of the European PV Cycle Association. Through the pre-financed PV Cycle program, Trina Solar
PV modules will be taken back and treated in an environmentally sustainable manner.*Applicable only to participating
