Step 6.
Grasp the handle on the rear of the power supply and slide the power supply forward into the
power-supply bay until it clicks. Make sure that the power supply connects firmly into the
power-supply connector.
Step 7.
Route the power cord through the handle and cable tie if any, so that it does not accidentally
become unplugged.
Step 8.
Connect the other ends of the dc power cable to the dc power source. Cut the wires to the
correct length, but do not cut them shorter than 150 mm (6 inch). If the power source requires
ring terminals, you must use a crimping tool to install the ring terminals to the power cord wires.
The ring terminals must be UL approved and must accommodate the wires that are described in
“Regulations” on page 256. The minimum nominal thread diameter of a pillar or stud type of
terminal must be 4 mm; for a screw type of terminal the diameter must be 5.0 mm.
