After you have installed the LX-4000 unit, you can connect the DC power as described in the following
procedure (refer to Figure 13):
1. Connect the LX-4000 to the facility's bonding network (or earth ground), using the points on the
rear panel of the LX-4000. The connection to the facility's bonding network should be made per
