1. Introduction
B50 Rail and Accessories constitute a system
that is widely used for PV Module mounting on
tin roofs. To make it robust and longevity, it is
manufactured from aluminium alloy and
stainless steel. With unique design, Z-module, it
provides high efficient installation and the
compatibility with most of frame PV-Modules in
the market.
Before system installation, please read the
installation manual carefully. The manual
provides the following content: (1) simple
introduction of installation; (2) product
installation specification；
Please use it according to the installation
instruction manual. Please pay attention to
safety when installing the product, and construct
it according to local laws and regulations. You
can confirm the latest installation manual on
www.clenergy.com if necessary.
The installer is solely responsible for:
•Complying with all applicable local or national
building codes, including any updates 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 PV-ezRack
project plan (substitution of parts may void the
warranty and invalidate the letter of
certification);
•During installation, ensure that the
self-tapping screws and metal screw have
sufficient strength and shear force;
•Keep the roof waterproof system intact;
•Recycling: Recycle according to the local
relative statute;
•Removal: Reverse installation process;
•Ensuring that there are no less than two
professionals working on panel installation;
•Ensuring the installation of related electrical
equipment is performed by licenced
electricians;
•The upper and lower limit of the torque of the
locking screws must be checked regularly at
least once a year.
•Changes and deviations from the planning
documents must be approved by Clenergy.

3.2 Precautions during Stainless Steel Fastener Installation
Improper operation may lead to deadlock of Nuts and Bolts. The steps below should be applied to
stainless steel nut and bolt assembly to reduce this risk.
3.2.1 General installation instructions:
(1) Apply force to fasteners in the direction of thread
(2) Apply force uniformly, to maintain the required torque
(3) Professional tools and tool belts are recommended
(4) In some cases, fasteners could be seized over time. As an option, if want to avoid galling or
seizing of thread, apply lubricant (grease or 40# engine oil) to fasteners prior to tightening.
3.2.2 Safe Torques
Please refer to safe torques defined in this guide as shown in Installation Instructions. In case 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.

4. Installation Instructions
4.1 Klip-lok Interface Installation
According your plan, mark
the position of Klip-lok
Interface on the tin roof with
Marker Pen and String.
Place Klip-lok Interface on
the marked position, as
shown figures on the right.
4.2 Rail Installation
4.2.1
To connect multiple rails
together, slide half of splices
on the rear side of the
pre-assembled rails. Fasten
the first M8 Allen bolt firmly
using the Allen key. Now
slide the next rail segment
into the other half of splice.
4.2.2
Tighten the second M8
Allen bolt using the Allen
key. The connection is
finished. An expansion gap
at the rail joints is
recommended. For this
purpose, leave a gap about
the same width as a finger

between the rail joints and
then loosely tighten the M8
Allen bolt.
Note:
Skip this step if the rail is
long enough and no need to
splice.
4.2.3
Affix the Rails and Klip-lok
Interface by Rail Clamp.
Recommend torque of M8
bolt is 18N.m
4.2.4
Repeat above steps and
install the rest of Rails.
Adjust Rails’position with
String, and align all ends of
Rails.

PV-Module on Rails with
Marker Pen. Stretch a String
as a reference to align
PV-Module. Place the first
PV-Module on the marked
position.
4.3.3
Slide and affix the End
Clamp to the side face of
PV-Module, as shown in the
figures on the right. Fasten
the bolt refer to below
recommend torque.

module into the channel of
the Rail first, then press
second leg of Z module into
the channel.
4.3.5
Buckle the Inter Clamp into
the Rail and affix it to the
side face of PV-Module.
Don’t fasten the bolt to
make the installation of
second PV Module easier.
