Figure 13 - Connecting DC Power

After you have installed the LX unit, you can connect the DC power as

described in the following procedure (refer to Figure 13):

1. Connect the LX to the facility's bonding network, using the points on

the rear panel of the LX. The connection to the facility's bonding

network should be made per local practices, using wire with a

minimum conductor size of 18 AWG.

2. Using a ¼-inch nut driver, remove the terminal block nuts.

3. Attach the facility’s “A” feed to the terminal block labeled “A”.

NOTE: Be sure that the -48VDC is connected to the minus side, and the

48VDC return is connected to the plus side.

4. Attach the facility’s “B” feed to the terminal block labeled “B”.

5. Replace the nuts and tighten them securely.

The DC leads should be 22 AWG or larger. They should be terminated

with a #5 ring terminal or larger depending on the wire size used.
