Step 5: Installing PV Modules to Power Rails with Module Clamps
PV Modules are secured to the Power Rail using Mid and End Clamps (Standard or
RAD), along with the appropriate attaching hardware. Attaching hardware includes
Carriage Bolts or RAD Bolts for Mid Clamps and End Clamps.
The importance of correctly installing End and Mid Clamps:
There is only one correct method of installing End Clamps and Mid Clamps. Failure
to follow the correct method could lead to personal injury, structural failure, and/or
damaged components. See Figure 5-1 for proper method of installation for an End
Clamp and Figure 5-2 for the Mid Clamp. Refer to these figures during the
installation of the Modules to prevent any undue problems associated with an
improper installation.

WARNING:
This is a two
person activity.
Modules are
heavy. One
person should
hold and align the
modules while a
second person
secures the
Modules with
clamping
hardware. Failure
to do so could
lead to serious
personal injury
and/or damaged
components.
CAUTION:
Be sure to tighten
the L-Bolts evenly
to close any gaps
and keep the Rail
Bracket tight
against the
Horizontal Pipe.
