Relay Switch Installation
Find a suitable placement to drill a hole for the A/C socket adapter.
Leave sufficient room under or above the hole to install the relay
switch circuit board. A ¼” minimum clearance will be required
between the circuit board and the edge of the hole.
Make a 1.25” (32mm) diameter hole in the case, using a 1 ¼” Bi-
Metal hole saw. Deburr the edges of the hole with sand paper.
Position and center the mounting plate over the hole as a template to
mark the locations of the plate’s mounting screws. Drill 2 holes of
.125” diameter for the mounting screws.
Install the mounting plate using the screws provided with your kit.
Insert the A/C socket inside the mounting plate.
