5. Neutral grounding

For neutral grounding you need to connect the internal ground cables:
Open the front panel and connect the neutral conductor of the AC
output (labelled 'Inverter Neutral') to the safety ground (labelled
'GND'), see picture. Integrate a ground fault circuit-interrupter (GFCI)
in the wiring of the AC output.
Neutral grounding is only active when the unit is in Inverter mode.
Neutral grounding will automatically disconnect when the AC input is
transferred to the AC output. For more information, see section 7.
For neutral grounding of systems with multiple units, see section 10.
Furthermore:
The chassis ground terminal must be connected to the central
grounding point of the vehicle/ ship.
Refer to locally applicable regulations regarding grounding of
autonomous power systems.
6. Installation
The installation of a stand-alone unit is described step-by-step at the beginning of this manual. The
location requirements, the recommended wire sizes, the optional control panel and the remote
switch are described in the following sections.
Choosing a location to install
Install the AC Master in a well-ventilated room protected against rain, snow, spray, vapour, bilge,
moisture and dust.
Ambient temperature: –25 ... 40 °C / –13...104 °F.
Never use the AC Master at a location where there is danger of gas or dust explosions.
Mount the AC Master in such a way that obstruction of the airflow through the ventilation
openings is prevented. No objects must be located within a distance of 10 cm / 4 inch around
the AC Master.
Do not install the AC Master in the same compartment as the batteries. Do not mount the AC
Master straight above the batteries because of possible corrosive sulphur fumes.
