Battery Warning Output Dry Contact Interface
The default function of J8 is the output dry contact interface, which presents the battery warnings
of low or excessive voltage, when the battery voltage is lower than set value, an auxiliary dry contact
signal will be activated via the isolation of a relay. The interface diagram is shown in Figure2-15,
and description is shown in Table 2-10.
