Step 1: Mounting the Power Optimizers
• Completely shaded modules may cause their power optimizers to temporarily shut
down. This will not affect the performance of the other power optimizers in the string,
as long as the minimum number of unshaded power optimizers connected in a string
of modules is met. If under typical conditions fewer than the minimum optimizers are
connected to unshaded modules, add more optimizers to the string.
• Do not leave the power optimizers connectors disconnected. Open connectors should
be mated to each other.

The images contained in the following sections are for illustrative purposes only and
may vary depending on product models.
Step 1: Mounting the Power Optimizers
For each of the power optimizers 1 :
1. Determine the power optimizer mounting location and use the power optimizer mounting
brackets to attach the power optimizer to the support structure . For frame-mounted
power optimizers follow the instructions supplied with the optimizers.
2. If required, mark the mounting hole locations and drill the hole.
CAUTION!
Do not drill through the power optimizer or through the mounting holes. The drilling
vibrations can damage the power optimizer and will void the warranty.
3. Attach each power optimizer to the rack using the M6 (1/4'') stainless steel bolts, nuts
and washers. Apply torque of 9.5 N*m / 7 lb*ft.
4. Verify that each power optimizer is securely attached to the supporting structure or the
module.
NOTE
Record power optimizer serial numbers and locations, as described in Providing
Installation Information on page 35.
