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® Commercial Tilt™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® Commercial Tilt™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.

4. Installation Instructions
4.1.1 According to the
installation plan, fix the front
leg and rear leg on the
ballast bar, check the size
and position, and then
tighten the bolts, as shown
in Fig. 1.
Note:
- The distance between the
front/rear leg end and the
ballast bar end shall accord
with the dimension
indicated on the project
drawings;
- Slide the front and rear leg
respectively in to the
mounting slots on the
ballast bar;
- Put the ballast bar upright,
so that it would be easier to
fix the front and rear legs.
Recommended tightening
torque for M8 bolt:
16-20N·m
4.1.2 According to the
installation plan, mark out
the installation position and
place the front and rear legs
accordingly, as shown in
Fig. 2.

4.1.3 Make sure the size
and position are correct,
and then place ballasts on
the ballast bars, as shown
in Fig. 3.
Be sure to keep enough
space between the ballast
and the front leg to avoid
impeding the assembling
due to excessively high
ballast.
When wind deflectors are
required, be sure to keep
enough space between
the ballast and the rear
leg, to avoid impeding the
wind deflector
installation.
4.1.4 Place the first PV
module on the front and
rear legs, with the frame
pressed against the limiting
edge of the front leg. A
distance of 44mm shall be
kept between the frame and
the front leg end and
between the frame and the
rear leg end, as shown in
Fig. 5.

4.1.5 Make sure the PV
module is placed properly
and levelly, and then slide
the end clamps into the
front and rear legs
respectively to fix the PV
module. Fasten the end
clamps as shown in Fig. 6.
Recommended tightening
torque for M8 bolt:
16-20N·m
4.1.6 Slide the inter clamp
into the front and rear legs
of the first PV module, as
shown in Fig. 7.
If grounding installation is
required, the grounding clip
shall be fixed in the inter
clamp, as shown in Fig. 8.
4.1.7 Place the second PV
module on the front and
rear legs, with the frame
pressed against the limiting
edges of the inter clamp
and the front leg, and then
fasten the inter clamp as
shown in Fig. 9 & 10.

4.1.8 Place the last PV
module in the first row onto
the front and rear legs, with
the frame pressed against
the limiting edges of the
inter clamp and the front
leg. Slide the end clamp
into place, check the
position and then fasten the

torque for M8 bolt:
16-20N·m
4.1.9 Install the remaining
PV modules according to
the above procedure as
shown in Fig. 12.
