Step 4 Insert the exposed wire of one of the four DC-input power source wires into the
terminal block plug, as shown in Figure C-7. Make sure that you cannot see any
wire lead. Only wire with insulation should extend from the terminal block.
Warning
An exposed wire lead from a DC-input power source can conduct harmful levels
of electricity. Be sure that no exposed portion of the DC-input power source
wire extends from the terminal block plug.

maximum torque is 4.5 lbf-in.
