4.5.3 AC Safety grounding
WARNING!
For safety reasons Ground Fault Circuit Interrupters (GFCIs), also known as Residual
Current Devices (RCDs), of 30mA must be integrated in the AC input and AC output of the
CombiMaster Inverter/Charger. Refer to locally applicable regulations regarding grounding
of autonomous power systems.
Neutral to Ground Bonding
To ensure a correct operation of Ground Fault Circuit Interrupters (GFCIs), the
grounding system jumper (located on the left side of the CombiMaster
Inverter/Charger) must be placed between N and PE. Then the Neutral (N) output
is automatically connected to the Safety Ground (PE / GND) if the AC input of the
CombiMaster Inverter/Charger is disconnected from an external AC source.
Default setting
4.5.4 Network wiring (CZone/MasterBus)
The CombiMaster Inverter/Charger can be connected to a CZone or MasterBus network. For CZone,
use an RJ45 Drop cable CZone/MB. For MasterBus, use a MasterBus cable and daisy chain the
CombiMaster Inverter/Charger to the other devices. Both networks need a terminating device on both
ends of the network. Do not make ring networks. For more details on networks, please contact your
Mastervolt supplier.
