3.2 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.
3.2.1 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.

System Overview
3.2.2 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.
3.2.3 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.
3.3 Installation Dimensions
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 for
Clenergy’s review prior to modification for comment and approval.

Installation Instruction
4. Installation Instruction
4.1 Pipe Installation
Dig a hole with the diameter of 300 mm.
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.
4.2 Steel Cap Installation
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：

Installation Instruction
4.3 Rectangular Tube-Master and Adjustable Tube Installation
4.3.1 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 .
4.3.2 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 .
4.3.3 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.
4.3.4 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.
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.

Installation Instruction
4.5 ECO Rail Installation
4.6 PV Module 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).
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.
