Improper operation may lead to the deadlock of bolts and nuts. Follow the steps below to reduce this risk.
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.
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.

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.
All drawings and dimensions in this installation guide are for generic reference. The PV-ezRack® PostMount 1-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 1-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 Instructions
Dig a hole to the diameter 300-400mm and depth 1200-1400mm
highlighted in the PM1-A engineering letter. Cover the bottom of
the hole with 50-70mm gravel.
Place the pole into the middle of the hole and fill it with concrete.
Maintain the position of the post. The allowed vertical tolerance
is ±2°.Keep the axle of the 2- Ø14 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- Ø14 holes aligned.
1) As show in figure on the right, with M12 * 120 hex bolts and nuts
to lock Angle Steel 63*40*1010 on the Pole. And then use M12 *
120 hex bolts and nuts to lock supporting rod 40 * 40 * 682 on the
Pole.
Note: supporting rod around multiple holes which can be
adjusted by adjusting the mounting, adjustable angle of 10 °, 20 °,
30 °, 40 °, 50 ° and 60 °.
Recommended torque for M12 bolts is 40~45 N·m

2) As show in figure on the right, place the ECO-Rail on Angle Steel.
Use the Cross Connection Clamp, Cup head square neck bolts
M8*25, Hexagon nut with flange M8 to lock on the Angle Steel 63 *
40 * 1010.
Recommended torque for M8 bolts is 18~20 N·m
3) Position the PV Panel landscape by aligning the centre line
with the ECO-Rail. And fix the PV Panel to the Rails by using End
Clamps.
Recommended torque for M8 bolts is 18~20 N·m

◦Wind average recurrence interval of 100 years for ultimate state and 25 years for
serviceability;
◦Wind region A, B, C & D;
◦Md=1, Ms=1 & Mt=1;
•Max. Solar Panel length 1750mmx1010mm;
•Steel members to be Q235B;
•Aluminium members to be AL6005-T5;
•Bolts to be SUS304;
•The certification excludes assessment of PV panels
•Refer to Table 1 for maximum tilt angle and footing options;
•Dimensions as shown here on the picture;

shown in this letter.
2. Other piers dimensions are possible, contact Gamcorp, if required.
3. Panel weight calculated: 20kg.
4. Embedment depth is relevant for soils, having adhesion capacity from 300mm
of the ground level; in other cases contact Gamcorp.
5. For concrete piers foundation, use 25 MPa strength concrete (minimum). It is
recommended to insert N12 bar 200mm long at the bottom of the post into the
concrete piers.
6. If any of the above conditions cannot be met, the structural engineer must be
notified immediately.
Construction is to be carried out strictly in accordance with the manufacturers instructions and
