2 INSTALLATION GUIDE
2.3.1 Input Wire Diameter Selection
REDARC recommends the installer use cabling and connections between 8B&S and 6B&S automotive.
REDARC recommends that the input wire be of the size outlined in Figure 2.3.1.1.
Distance from input vehicle
battery to The Manager30

2.3.2 Output Wire Diameter Selection
REDARC recommends the installer use cabling and connections between 8B&S and 6B&S automotive.
REDARC recommends that the output wire be of the size outlined in Figure 2.3.2.1. For longer runs, using
6B&S (13mm
2
) is recommended, however this will lower efficiency by up to 3% (the recommended
maximum length is 16'5" (5m).

FIGURE 2.3.2.1: Recommended output cable size
REDARC recommend using the SBI12-BLD as
the 12V relay for setting up the Load Disconnect
Feature for nonessential Loads.
Similarly, the SBI12-LLD is recommended for
use between the Auxiliary/House battery and
the Essential Loads in a Lithium Battery setup,
to protect the Lithium battery from excessive
discharge.
