2. 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.
Proceed with electrical connections as described in fig.3

The 4 pins Molex connector will then connect to the
computer power supply.

3. Power Supply ventilation
The following information is optional, and subject to existing ventilation in your particular chassis. Please disregard if your computer chassis already
features a blowhole, with or without fan.
The S320-12 power supply features a built-in temperature controlled fan, which activates as needed. Since the power supply is being installed in a
confined area, and in order to reduce a heat build-up inside the chassis, it is essential to optimize exhaust of the hot air generated by the power
supply. A blowhole will accomplish just this, and should be located as close to, or preferably directly above the power supply exhaust vent. Ideally,
a low CFM 80mm fan should be added, if space permits. Such solution will greatly the activity of the power supply built-in cooling fan, resulting in
quieter operations, and lower temperatures both inside the computer and in the power supply. If such fan is installed, it should be extracting air from
the case (blowing towards the outside).
