Step 7
Ensure that the terminal block plug is fully seated in the terminal block header on the DC power supply panel. The plug
has a locking feature. You should hear a snap or click when it is installed properly.
Step 8
Use a tie wrap to secure the wires to the rack, so that the wires are not pulled from the terminal block plug by casual
contact. Make sure the tie wrap allows for some slack in the ground wire, as shown in the figure below.

Step 9
Use a tie wrap to secure the wires to the handle. Leave a service loop on the ground wire between the handle and the
