Chapter 3 Installing the Router
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 3-22 or 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).

Step 6 Install the plastic cover over the terminal block.
Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover
installed. Operating the unit without the cover in place will invalidate the safety approvals and pose
a risk of fire and electrical hazards. Statement 117
Step 7 Secure the wires using cable ties.
