INSTALLATION STEPS (QUICK GUIDE)
1. Mark out all fire setbacks on the roofing 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 fixed attachment points as required by the plan set for anchored hybrid systems, seal/flash in accordance with the roofing 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.
The 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 find the approx. Chassis spacing within 1/8″. For more precise measurements use the formulas provided at the bottom of the table.

1. MARK LAYOUT
Using the approved planset, mark out all fire 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.

2. PLACE CHASSIS
Place first 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 are required to be moved inward from the perimeter reference lines so that they are fully underneath the modules.
When a Chassis is shifted inwards under a module, clamps should be installed on all corner bolts supporting the module.
Always wear gloves when handling BX Chassis.
3. MOUNT MLPE (OPTIONAL)
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.
