Installation
Step 1:
Attach Claws to Modules (Prep)
1.1.
Lay module, glass side down, on work surface.
1.2.
Place Claw over mounting hole while resting Claw flange against outside edge of module
(reference the “ARRAY DIMENSIONS” table in the
Racking Construction Set if the module has
more than four mounting holes).
1.3.
Insert bolt through the Claw and module hole.
Note:
Shift the claw towards the module junction box such that it “bottoms out”
against the
bolt. This will ensure that the claws on the module are always consistently spaced.
1.4.
Reach under the module frame flange and thread nut onto bolt until snug.
1.5.
Press Claw tab against module frame and tighten bolt to 8-10 ft-lb (96-120 in-lb) of torque
).
1.6.
Repeat Steps 2 through 5 for the second Claw.

:
Set up Spacer Stick
2.1.
Consult the Racking Construction Set for the Support spacing between modules (Spacing L) and
Support spacing under modules (Spacing Q) (
). Dimensions L and Q are module
dependent and vary by manufacturer. In some scenarios L is longer than Q while for others it is
the opposite.
2.2.
Reference the Q and L dimensions on the Racking Construction Set drawing. Set two spacer
stick brackets to the Q dimension and 2 spacer stick bracket to the L dimension.

Note: All the claws need to be in the
same orientation relative to the junction
box. (Exceptions: When using optimizers
or due to string requirements)
