1. Introduction
Clenergy PV-ezRack® SolarTerrace II-F™ (STII-F) is a pre-assembled ground
mounted system suitable for large scale commercial and utility scale PV installations.
STII-F has been developed to be compatible with common PV Modules, including
framed and frameless PV Modules. The innovative and patented STII-F TR-Rails are
not only suitable for flat land, but also suitable for eastern and western facing slopes
and high snow load areas.
Please review this manual thoroughly before installing STII-F. This manual
provides the following contents: (1) Installation planning; (2) Installation instructions;
When installed in accordance with this guide, the mounting structure will be
structurally adequate and adhere to related standards. During installation, and espe-
cially when working on the ground, please comply with the appropriate occupational
health and safety regulations. Please also pay attention to other relevant regulations
in your local region. Please check that you are using the latest version of the
installation manual by contacting Clenergy via email on sales @clenergy.co.jp, or
contacting your local distributor.
The installer is solely responsible for:
Complying with all building codes according to any applicable place or country
that may supersede this manual.
Ensuring that PV-ezRack and other products are appropriate for the particular
installation and the installation environment.
Using only PV-ezRack parts and installer-supplied parts as specified by
Clenergy (substitution of parts may void the warranty).
Recycling: according to local related statutes.
Disassembly: reverse installation process.
Ensuring that there are no less than two professionals working on panel
installation at the one time;
Ensuring that all related electrical equipment is installed by a professional

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.
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.
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．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.

Note: Do not fasten bolts tightly until each component is adjusted properly. Repeated
fastening or unlocking will result in bolt galling / deadlock.
3.3 Installation Dimensions
All drawings and dimensions in this installation guide are for generic reference. The
PV-ezRack STII-F is to be optimized to suit specific conditions for each project and
documented in engineering drawings. Asa result,major componentsof the PV-ezRack
STII-F may be provided in sectional sizes and lengths that vary from those shown in
this guide. The installationoperations detailed in thisinstructionguide remain the same
regardless of the component size. In case any on-site modifications or alteration of the
system are needed, 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.

4.1.2 According to the
installation plan, use the total
station to mark the ramming
position of each C-Post.
When ramming, ensure that
the C-Posts in the same row
are in line and facing the
same direction. Also pay
attention to the opening of
the C-Posts and ensure they
are aligned towards the same
direction.

Fix the Post Head on the post
and fasten it with M12
Hexagonal bolts and nuts as
shown on the right figure.
Recommended torques:
Bolt 1: 50-55 N•m
Bolt 2 :23-25 N•m
The ribbed surface of the Post Head cap should be
facing the same direction as the opening direction of
the post and the bolt head
