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 4-A 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 4-A 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
4.2 Steel Cap Installation
Connect the Pipe to the corrugated washer and Steel Cap Assembly with M14*150 hexagonal bolt, washer
14, Hexagon nut M14.
Combine two Steel Caps with M14*110 hexagonal bolt, washer 14, Hexagon nut M14.
Note：
1. Do not fasten the M14*110 Bolt prior to complete the assembly of PM4-A Rectangular Tube-Master.
2. Keep all the Bolt head aligned.
4. Installation Instruction
4.1 Pipe Installation
Solution 1：Pole Pre-buried
Dig a hole with the diameter of 300 mm.
Place the pipe into the middle of the hole and fill it
with concrete(min 25 MPa strength). Maintain the
position of the pipe. 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.
Solution 2: Flange Based Pole
Secure the Flange based Pole to the concrete
foundation with M16 foundation bolts. Axis of 2- Ø16
hole is parallel to west, angle tolerance is within±5°,
and 2- Ø16 holes direction of all poles is consistent.
Recommended torque for M16 bolts is 145~150 N·m

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.
