Overview Diagram
10mm
The diagram on the following page gives an overview of the basic wiring with respect to the grid supply and the
microgeneration system.
Supply
The
zappi
device should be connected to a single-phase 230V or 240V nominal AC supply. The supply should be from a
dedicated 32A or 40A circuit breaker.
Earthing
The unit must be earthed in accordance with local regulations, e.g. It may be a requirement to install an Earthing rod if the
supply is PME.
Cable Entry
There is a grommet in the rear of the unit for through-wall cable installation. If however, the supply and/or sensors cables are
surfaced mounted, there is space at the bottom right-side of the enclosure to drill holes for the cables. It is essential that
correctly sized cable glands with a minimum IP65 rating are used.
