DRILL TEMPLATE INSTRUCTIONS

Cut out the drill template on the following page, fold the edges and tape it to the enclosure. Before

drilling, it's recommended to first use a center punch for each of the holes to help guide the drill bit.

Ensure that the template is printed at 100% or "Actual Size". You can double-check this by measuring the

scale on the printed page with a ruler or calipers.

The LEDs are sized for plain LEDs with no bezel, mounted directly to the PCB. If you don't have a 5mm

bit for the bypass and channel LEDs, use 7/32". If you don't have a 3mm bit for the limit LED, use 1/8".

Important: Due to the high number of PCB-mounted parts, it's crucial that the drilling be accurate. Since

the PCB uses slotted holes for the toggles, there's not a lot of room for error.

If the toggles don't align to the PCB, you can always drill one step larger (9/32") to allow a little more

room correct any errors. The toggle switch washer and nut will still fully cover the hole.
