    Chapter 3 Installing the Router When stranded wiring is required, use approved wiring terminations, such as closed-loop or Warning 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 Remove the plastic covers from the terminal block.

    Power Connections The safety cover is an integral part of the product. Do not operate the unit without the safety cover Warning 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 Secure the wires using cable ties as shown in Step 7 and to the right of the terminal block.
