Figure 2-7, DC Wiring Connection Points
DC1
Inverter DC Negative Connection – Top of DC negative busbar connects to Magnum
inverter’s DC negative terminal.
DC2
Inverter DC Positive Connection – Top of DC positive busbar connects to Magnum
inverter’s DC positive terminal.
DC3
Battery Bank Negative Connection – Bottom of DC shunt connects to the battery
bank’s negative terminal.
DC4
Battery Bank Positive Connection – Bottom of the inverter’s DC disconnect breaker
connects to the battery bank’s positive terminal.
DC5
DC Grounding Electrode Connection – The connection point for the MMP/inverter
system to the DC grounding electrode. Use DC5A for greater than #1/0 AWG wires and
DC5B for #6 to #1/0 AWG wires.
DC6
DC Equipment Grounding Connection – The common DC equipment ground point
for all DC equipment used in the MMP/inverter system.
DC7
PV Positive Connection – Connects the positive output of a PV array and the positive
input to the PV charge controller.
DC8
DC Negative Connection – The battery negative common point for connecting
additional DC circuits, such as from the DC negative output of a charge controller or
combining the negatives of DC load circuit breakers.
DC9
Battery Positive Connection – Serves as the battery positive connection point for
additional DC circuits (from charge controller output or connecting to DC load breakers).
