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.

Installation Instruction
Dig a hole with the diameter of 300mm .
Place the pole into the middle of the hole and fill it with concrete
(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.
Note:
1. Do not fasten the Bolt prior to complete the assembly of PM-A Rectangular Tube-Master.
2. Keep all the Bolt head aligned.

Note:
1: Adjust the angle of the allation, the angle of the Rectangular
Tube-Master with 10° (6 holes from up to bottom corresponds to
10° to 60° tilt angle) in order to make the assembly process run
smooth.
2: Using the adjustable washer to avoid the gap between the
Rectangular Tube-Master and the Adjustable Tube. Unreliable
connection is forbidden.
1) Fix the Rectangular Tube-Master at Steel Cap Assembly with
M14*120 hex bolt, M14 nut, plain washer 14, and spring washer 14.
See the mark (1).
20 Fix the Adjustable Tube at Rectangular Tube- Master with
M14*120 hex bolt , plain washer 14, and spring washer 14, M14 nut.
See the mark (2).
3) Fix the Adjustable Tube at Steel Cap Assembly with M14*120 hex
bolt, M14 nut, plain washer 14, and spring washer 14.
See the mark (3).
Realized the angle adjustment by position the bolt in the differrent
holes.
4) Fasten the Steel Cap Assembly to Pipe with M14*150, M14*110 Hex
Bolt, keep the Rectangular Tube-Master parallel to the south-north
by adjust the Steel Cap Assembly.
Recommended torque for M14 bolts is 95~100 N·m.

- Installation Instruction -
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.
Note:
Do not fasten the M8*70 hex bolt in order to make other clamp fit well.

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).
