Power Connections

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. Statement 1002

Step 4 Remove the plastic cover from the terminal block. Save it for reinstallation after you finish wiring. Step 5 Connect the DC power input wires to the terminal block as shown in Figure 3-22or Figure 3-23.

Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire should always be connected first and disconnected last. Statement 239

Caution Do not overtorque the terminal block screws. The recommended torque is 8.0 ± 0.5 in-lb (0.9 ± 0.05 N-m).
