connects to the PSX-T chassis. Ensure that each lead is securely tightened, then replace safety
shield. When power is applied, the green PWR LED will illuminate
NOTE (1):
Always use a voltmeter to measure the voltage of the incoming power supply
and figure out the +ve potential lead or -ve potential lead. The more +ve potential lead will
connect to the post labeled “+ve” and the rest to the “-ve”.
The GND can be hooked up at the last.
NOTE (2):
For best results at high-temperature, fasten the metal case of the PSX unit
to be in contact with a vertical surface (such as pedestal) that has good heat conducting
properties. Remove rubber “feet”, if present, to enhance metal-to-metal contact and provide the
best heat transfer away from the PSX unit.
