1. Introduction
The Clenergy PV-ezRack Grounding system has been developed as a univer¬sal earthing system to work with all
Clenergy PV-ezRack products. It has been designed in accordance with UL 467 standards.
This installation manual applies only to PV-ezRack SolarRoof (Tin, Tile and Tilt).

2. System Overview
Important Note:VC
Use geneCral purpose anti-seize compound on fastener threads when installing Grounding Clips and Lugs.
Grounding Clips and Lugs are intended for SINGLE USE ONLY. Functionality will not be guaranteed if reused.
The Grounding System can be used to bond anodized aluminium, galvanized steel, steel and other electrically
conductive metal structures.
Grounding Clips are used to bond the
modules to the rails
Grounding Lugs are used to connect the
rails together and bond the system

C. Patented Z Module
D. M8 Bolt
Pre-assemble the Grounding Clip with the inter clamp assembly as shown.

4. EZ-GC-ST installation instruction
Slide pre-assembled Grounding Clip and inter clamp assembly into position as shown,
opening under the first
Slightly lift the solar module and slide the Grounding Clip and inter clamp assembly into
position. The Clip’s teeth will automatically be aligned under the edge of the module
when the inter clamp assembly is correctly installed.
ImportaCCCCCnt Note:
To correctly install the EZ-GC-ST, ensure that the solar
modules are fully in contact with the inter clamp.
Visually check that the EZ-GC-ST is properly positioned,
teeth fully covered by the frame of the panel.

•
Do not use a module with a frame that prevents the Grounding Clip teeth from embedding fully.
The EZ-GC-ST is designed for SINGLE USE ONLY! Do not tighten fasteners down if the position of
solar modules is not finalized. Only slightly tighten fasteners to keep modules in place.

4. EZ-GC-ST installation instruction
•
•
When the positioning of the solar modules is finalized, ttighten the fasteners to 15ft-lb/20.5N-m torque using
general purpose anti-seize compound
Certain module frames do not have enough structural strength to withstand the force required to embed a Clip.
These frames will deform and therefore not allow sufficient penetration of the Clip teeth. The general requirements
for minimum module frame thickness of ‘boxed’ type module frames are illustrated below.

5. EZ-GC-ST Layout
To ensure that all the modules are correctly bonded to the rails you need to use 1 grounding clip per
panel and per rail.
Note:
When replacing a single faulty module, also remove the adjacent module which contacts the same
Grounding Clip as the faulty module. This will ensure that there are never ungrounded modules in
the array.

•
Even number of modules in a row
X DENOTES PLACES TO INSTALL Grounding Clip
Number of Grounding Clip = Number of modules
Odd number of modules in a row
X DENOTES PLACES TO INSTALL Grounding Clip
Number of Grounding Clip = Number of modules +1

Lay in copper wire and torque bolt to 7 ft-lb/10N-m
Important Note:
Ensure that the position is correCct before tightening.
The Lug may be used with a ground wire of maximum 6AWG.

9. Connecting rails
• Clenergy splice kit provides the electrical connection between the 2 rails through the pressure
bolts.This eliminates the need of using a jumper or 2 lugs.
