INSTALLATION STEPS (QUICK GUIDE)
1. Mark out all re setbacks on the roong plane.
2. Measure and mark out footprint of array according to the approved planset location.
3. Starting at the south edge of the approved planset, chalk the South Array Edge, making sure that this line is at
least 8" away from the South Fire Setback.
4. Measure Chassis spacing (refer to chart below) and chalk out 3 rows, 25’ each.
5. Measure out the Chassis locations by marking along each row, module width plus 3/8”.
6. Place Chassis on cross hairs. Align cross hairs with alignment marks on Chassis.
7. Install MLPE as needed.
8. Load Chassis with blocks as per the plan set.
9. Install xed attachment points as required by the plan set for anchored hybrid systems, seal/ash in accordance with
the roong manufacturer’s guidelines.
10. Module Installation
a. Place all Bottom Clamps on Chassis.
b. Land all panels on Chassis.
c. Place all Top Clamps and ensure proper alignment and engagement of the Bottom Clamp.
d. Make sure that all Clamps are fully engaged and square to the module and torqued appropriately.
11. Complete Array Bonding
a. Install 8” Module Bonding Jumpers between all modules along the rows.
b. Install 38” Row Bonding Jumpers between all rows.
12. Install PV Module Grounding Lug to ground each array.
It can be helpful on constrained arrays to chalk line every row, but it is not required.
e illustration below shows the order of chalk operations for marking out the starter array, as well as a corresponding Chassis spacing
table which can be used to easily nd the approx. Chassis spacing within 1/8". For more precise measurements use the formulas
provided at the bottom of the table.

1. MARK LAYOUT
Place rst Chassis at Southwest corner of the array,
aligning the center reference hole with the cross hair
marker. Repeat for each additional Chassis in the array.
➢After the array has been installed, the Chassis at the East and
West edges of the array should be moved inward from the
perimeter reference lines so that they are fully underneath the
modules.
2. PLACE CHASSIS
Using the approved planset, mark out all re setbacks and
the array foot print on the roof(s).
Mark the South Array Edge with a 25' line (for example).
If the southern edge of the array is against the South Fire
Setback, mark the South Array Edge at least 8" away from
the setback. This will ensure that no part of the Chassis is
in the setback.
Measure Chassis spacing (refering to table on Page 5)
and chalk out 3x 25' rows. Then measure out the Chassis
locations by marking along each row (module width plus
3/8").
➢These layouts are useful for maintaining a straight line at the start
of the array. Once started the rest of the system is build as you
go.
Mount microinverters and power optimizers directly to
the Chassis using the MLPE Mounting Hardware Kit.
Alternatively, you can use a third party module mounting
bracket (following manufacturer instructions).
To install the MLPE Mounting Hardware Kit, place the
Cage Nut into either of the square cut-outs on the lower
edge of a Chassis. Secure your MLPE device with a 5/16"
Flange Bolt torqued to 60 in-lbs.
