5. Prepare the other end of the harness for connection with the 24V DC industrial
power supply, by doing the following:
a. Strip the wires about 6-7 mm.
b. If desired, apply a splice cap to each of the three stripped wires.
This step is optional.
Refer to your 24V DC industrial power supply's instructions for further information on
preparing the wires.
6. Use a digital voltmeter to verify that your 24V DC industrial power supply's
output voltage is indeed 24V DC.
7. Connect the 24V DC industrial power supply's end of the harness to the 24V
DC industrial power supply's terminal block, by doing the following:
a. If unsure, use a digital voltmeter to determine which of the 24V DC
industrial power supply's posts is the (+).
b. Connect the Green and Yellow (GND) wire to the (GND) post in the
terminal block.
This wire must be connected first.
c. Connect the Black (-) wire to the (-) post in the terminal block.
