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. De-burr 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:

• Black L wire from A/C socket to N\O (normally opened)

position on switch

• Black L wire from S320-12 power supply to N\O position

on switch

• White N wire from S320-12 power supply to N position on

A/C socket

• Green Ground wire from S320-12 power supply to Ground

on A/C socket

• The 4 pins Molex connector will then connect to the

computer power supply.


Note that connection of the TEC wires to the S320-12 power supply
will take place at the very end of the installation, once your
hydraulic circuit has been leak proofed (chapter 2.7)
