C.1.1.2 Installing the Wiring
1. Strip the wire insulation to approximately 1.27 cm (.50 in.).
2. Insert the wire into the terminal block as follows:
a. Observe the wire color/polarity
–
Black: -48 Vdc
–
White: +48 Vdc
–
Green/yellow: Ground
b. Torque the #10-32 compression screws to 40 to 45 inch-pounds.
