Phase/Phase Rotation
Single Phase
zappi
The Phase setting is only used when installing a single phase
zappi
onto a 3-phase
supply.
It should be set to match the phase number that the
zappi
is wired to so that the power
measurements are correct and that the
zappi
responds to the correct phase when using
the
harvi
wireless sensor.
Three Phase
zappi
The Phase Rotation setting is only used on three phase units and should correspond to
the wiring to the input terminals. Only the following specific options are available:
1/2/3 (Phase 1 wired into “L1”, Phase 2 wired into “L2”, Phase 3 wired into “L3”)
2/3/1 (Phase 2 wired into “L1”, Phase 3 wired into “L2”, Phase 1 wired into “L3”)
3/1/2 (Phase 3 wired into “L1”, Phase 1 wired into “L2”, Phase 2 wired into “L3”)
See Three-Phase Systems (page 51) and Net Phases (page 28) for more information.
Phase Return
Single Phase
zappi
only
When a single phase
zappi
is installed on a 230V delta connected supply, it is necessary to tell
zappi
which phase
has been connected to the neutral terminal.
Note: In most installations the Phase Return setting should be left as “N” for Neutral
Device Limit
Sets the maximum current that the
zappi
will draw (including when boosting and FAST mode). This is useful if the
supply current is limited, for instance, if
zappi
is connected on a 16A circuit instead of a 32A.
Neutral Limit
In some countries the electricity distribution company limit the maximum current that can flow in the neutral
conductor on a three phase supply (for example, the neutral current is limited to 20A in Germany). Use this setting
if a neutral current limit is specified for your installation.
Earthing
Before starting a charge,
zappi
carries out a check to make sure that the protective earth conductor is still
connected. This check only works in a TN or TT connected electricity supply. If you are on an IT supply or find that
the protective earth check is too sensitive then change this setting to “IT”.
