Procedure 2-14
Installing a DC Power Cable
The following procedure explains how to install the DC power cable.
Step
Action
1
Prepare the DC power cord. The power cord should be 14 AWG to 18 AWG
wire and should be of a length suitable for your installation. Remember to
allow the necessary slack for the cable to be properly retained between the
chassis and the terminal block. You will also need to install fork terminal
spade lugs for the installation environment on the wires. Use UL/CSA
approved parts and local practices to install spade lugs at both the chassis
and terminal block ends of the power cord.
Note:
provides a summary of the DC lugs that are
recommended for use with the 3916.
Note:
After it is installed, the power cord will be dressed to the left. It is not
appropriate to dress the power cord to the right, across the front of the 3916
chassis
2
Remove power from the DC circuit that will supply power to the system.
3
Using a flat head screwdriver, remove the plastic terminal block cover from
the front of the power supply and set it aside.
4
Use the terminal block on the front of the DC power supply to connect the
wires as follows:
•
Ground — connect to the right connector
•
Negative — connect to the middle connector
•
Positive — connect to the left connector
Note:
Make the ground connection first. The wires should be installed so
they flow down from the terminal block. The power cabling will be dressed to
the left in
