The terminal block is 3 positions, pin 1, towards the board edge, is Ground (GND). Pin 2 is unconnected
and must be left unconnected. Pin 3 is the +15 VDC terminal.
Loosen the Cable Gland by turning the knurled knob counter-clockwise until the cable slides freely.
Using a small flat blade screwdriver, unscrew and loosen terminals 1 and 3 on the terminal block J101 to
release the wires. The Brown wire is +15 VDC and goes to terminal block J101, terminal 3. The Black wire
is Ground (GND) and is connected to terminal block J101, terminal 1. Remove the wires from terminal
block J101 and pull the cable out of the chassis.
Push the new power cable through the cable gland, from the outside to the inside. Leave it loose until
the wire is attached to the terminals. (We use the heat shrink tubing to protect the cable from the cable
gland. This is optional if you are replacing the cable with one of your choice.) Strip no more than ¼” of
insulation from your wires and insert the wire you use for +15 VDC to pin 3 of terminal block J101.
Tighten the screw firmly. Insert the wire you use for Ground (GND) to pin 1 of terminal block J101.
Tighten the screw firmly.
