2. Precautionary Measures for Stainless-Steel
Fastener Installation
Improper operation may lead to the deadlock of bolts and nuts. Follow the steps below to reduce this risk.
Reduce the friction coefficient
(1) Ensure that the thread surface is clean (no dirt or contaminant).
(2) Apply lubricant (grease or 40# engine oil) to fasteners prior to tightening to avoid galling or seizing
in the threads.
General installation instructions
(1) Apply force to fasteners in the direction of thread.
(2) Apply force uniformly to maintain required torque.
(3) Professional tools and tool belts are recommended.
(4) Avoid using electric tools for final tightening.
(5) Avoid working at high temperatures.

Safe Torques
Please refer to safe torques defined in this guide as shown in the figure below. If power tools are required, Clenergy
recommends the use of low speed only. High speed and impact drivers increase the risk of bolt galling (deadlock). If
deadlock occurs and you need to cut fasteners, please make sure that there is no load on the fastener before you cut it.
Avoid damaging the anodized or galvanized surfaces.
All drawings and dimensions in this installation guide are for generic reference. The PV-ezRack® PostMount 3-A for
XL Panels is to be optimized to suit specific conditions for each project and documented in engineering drawings. As
a result, major components of the PV-ezRack® PostMount 3-A for XL Panels may be provided in sectional sizes and
lengths that vary from those shown in this guide. The installation operations detailed in this instruction guide remain
the same regardless of the component size. In case you need to do any on-site modifications or alteration of the
system in a way that would be different from engineering drawings, please provide marked up drawings/sketches
forClenergy’s review prior to modification for comment and approval.

(min 25 MPa strength). Maintain the position of the post. The allowed
vertical tolerance is ±2°.Keep the axle of the 2- Ø16 holes parallel to
East-West;keep the vertical angle deviation within ±5°.For more than
one system on one site maintain all the axles of 2- Ø16 holes aligned.
Connect the Pipe to the corrugated washer and Steel Cap Assembly with M14*150 hexagonal bolt, plain washer 14,
spring washer 14, M14 nut .
Combine two Steel Caps with M14*110 hexagonal bolt, plain washer 14, spring washer 14, M14 hex nut.

1) Fix the 3 pcs PM3-A Rectangular Tube-Landscapes at Rectangular Tube-Master with 3 pcs U-bolts, 6 pcs M10 nuts , 6
pcs spring washers 10, and 6 pcs plain washers 10. Do not fasten the Nut until 3 Rectangular Tube-Landscapes aligned.
Note:
Adjust the Rectangular Tube-Landscapes until the dimension D1=D2, D3=D4.
Recommended torque for M10 bolts is 35~40 N·m.
4. Rectangular Tube- Landscape Installation
2) Preassemble the Cross Connection Clamp at the Rectangular Tube-Master with M8*70 hex bolts, plain washer 8,
spring washer 8, and M8 nut as shown in the figure below.

Fix the PV panel to Rail, via Universal Inter Clamps and End Clamps step by step until all the panels complete.
Recommended torque for M8 bolts is 18~20 N·m.
- Installation Instruction -
5. ECO-Rail Installation
Uplift the Cross Connection Clamp in the certain angle. Click the Clamp into the ECO-Rail. Position the Rail in the
middle of the Rectangular Tube-Master, and then fasten the M8*70 bolt.
Recommended torque for M8 bolts is 18~20 N·m.
Note:
ECO-Rail of 3150 mm is a standard length in this system, which can be suitable for up to 1002 mm wide panel. If the
panels are over 1002 mm (less than 1100 mm) wide, the required minimum rail length is: (panel width-1002)*3+3150
(mm). For example, panels are 1050 mm wide. The required minimum rail length is (1050-1002)*3+3150 = 3294 mm. For
convenience, the rail length is rounded up to 3300 mm (multiple of 50 mm).

Clamp, and when the side of the Universal Clamp close the wide side of the Universal Clamp Buckle, it can be used as
Inter Clamp, as shown in the figure below.The Universal Clamp can be directly rotated to the position of required End
or Inter Clamp.
Recommended torque for M8 bolts when it is Inter Clamp is 18~20 N·m.
Recommended torque for M8 bolts when it is End Clamp is 13~14 N·m.

Notes:
1. Terrain Category 2 (TC2) refers to open terrain, including grassland, with well-
scattered obstructions having heights generally from 1.5m to 5m, with no more than
two obstructions per hectare. This certificate will only cover Postmount PM3-A/2100
installed on TC2.
2. Panel weight calculated: 28kg
3. Solar Panels structural check by others.
4. Other piers dimensions are possible, contact Clenergy, if required.
5. For concrete pier foundations, use 25Mpa strength concrete (minimum).
6. The scope of this certification is for projects located at a maximum altitude of 100m
above sea level. No snow loads have been assessed.
7. If depth of footing is less than length of post below ground (embedment depth of post)
the post must be cut to suit the new level.

8. Footing depths are for reference only. The characteristics of the soil must be checked
on site by a technical expert. A soil report assessment is always recommended and
Clenergy must be informed on the outcome of the soil report.
Construction is to be carried out strictly on accordance with the instruction manual. This work
was designed in accordance with the provisions of Australian Building Regulations and in
accordance with sound, widely accepted engineering principles.
