3.6. Connecting a Digital Multi Control or a VE.Bus Smart dongle

on/off/charger-only control of the inverter/charger.
Note that in systems containing a Digital Multi Control and a GX device or a VE.Bus Smart dongle at the same time, on/off/
charger-only control of the inverter/charger is only possible via the Digital Multi Control.
For example, the VE.Bus Smart dongle, Digital Multi Control and the GX device can all be connected simultaneously to the
Remote panel port. However, in this scenario, on/off/charger-only control of the inverter/charger via the GX device and VE.Bus
dongle is disabled. Since inverter/charger control is disabled, the GX device or VE.Bus Smart dongle can also be connected to
the MultiPlus/Quattro port of the BMS for easy wiring.

VE.Bus BMS V2
The VE.Bus Smart dongle needs to measure the battery voltage. Therefore its Battery+ terminal must be connected
to the positive battery terminal. Be aware that the VE.Bus Smart dongle will not be turned off by the BMS in case of a
low cell warning and will continue to draw current (up to 9mA - see the
from the battery.
