Installation Steps
Insert ground screws into the
ground according to Chico’s drawing.
Install the beam on front leg and rear leg by hex bolts M1080 (1 flat
washer, 1 spring washer, 1 nut).
M10: tighten torque is 30N.m; safe torque is 40N.m;
The front V leg and rear V leg are pre-assembled with V bases by hex bolts
M1080 (1 flat washer, 1 spring washer, 1 nut).
M10: tighten torque is 30N.m; safe torque is 40N.m;
*Connect the V leg bases to ground screws by hex bolts M1235 (2 flat
washers, 1 spring washer, 1 nut);**
M12: tighten torque is 50N.m; safe torque is 55N.m
Connect rail to the beams by hex bolts M1030 (1 flat washer, 1 spring
washer, and 1 nut);
M10: tighten torque is 30N.m; safe torque is 40N.m;
use rail splice kit to connect 2 rails by hex bolts M1030 (2 flat washers,
1 spring washer, and 1 nut).
M10: tighten torque is 30N.m; safe torque is 40N.m;
*Install the strengthen pipe between two rear V legs by hex bolts M1060 (2
flat washers, 1 spring washer, and 1 nut).
M10: tighten torque is 30N.m; safe torque is 40N.m;
Install panels onto rails by fastening mid and end clamps.
Note : End clamps by inner hex bolts M825 (1 spring washer, 1 plastic
steel nut); Mid clamps by inner hex bolts M850 (1 spring washer, 1 plastic
steel nut).

Double-check to make sure all bolts are fastened tight after installing all
the panels.
Steel U2V Ground Mount Installation Manual
Grounding System
The grounding function of the whole mounting system connections is achieved by the following steps
- Grounding Mid Clamp and Grounding End Clamp: Grounding Solar Panel
- Rail Splice Kit: connect two rails
- SUS Bolt and Nut: All mounting system connected
- Ground screw: connect the mounting system to the ground
- Grounding Lug
- Copper wire ( or other steel products) : connect the mounting system to the ground ( if not ground screw foundation, such as concrete)
Installation herein in accordance with the National Electrical Code,
ANSI/NFPA 70.
The grounding function of the whole mounting system connections is achieved by
the following devices:
- .T-bolt of the 19# hook: connect 19# hook with rail (see step4)
- Rail splice kit: connect two rails (see step4)
- Grounding end clamp: connect panel with rail (see step5 &7)
- Grounding mid clamp: connect two panels with rail(see step6)
- Grounding lug: connect rail with copper wire (see step8)
- Copper wire: connect the mounting system to the ground (see step8)
Grounding Lugs are intended to for use with one solid or stranded copper wire, conductor size 10-4 AWG.
CONTINUING MAINTENANCE
a)‘Any loose components or fasteners shall be re-tightened in accordance with
these instructions’, b)Any components showing signs of damage that compromise
safety shall be replaced immediately,’
FOR SINGLE USE ONLY
Bonding and grounding devices, are “For single-use only”, NOT multiple use)
Module removal may disrupt the bonding path and could introduce the risk of
electric shock. To ensure that the bonding path remains intact, additional
steps may be necessary; qualified persons should follow the instructions in
this manual.”
Scenarios that could result in a disruption of the bonding path are irregularly-shaped arrays, arrays consisting of individual rows or any other scenario where module removal could disrupt the bonding path.
Installation of Grounding Lug
Install a grounding lug (50mm from the rail end) onto each rail line edge with an inner hex bolt M825 and a stainless steel nut, then cross 8.4mm2 (greater than or equal to 8AWG) copper wire through all the grounding lugs (fixed by M820 inner hex bolt), finally connect copper wire to the ground. The grounding lug has grounding function when fastened tight to connect rail and copper wire.
M8 Torque: 15~20N.m
