IMPORTANT: Plug and Socket Alignment

aligned. It is possible to make an incorrect
connection where, plug terminal 1 for example
is connected into socket terminal 2, and plug
terminal 2 for is connected into socket
terminal 3, and so on.

Configure Load Balancing
Configuration of the load balancing system is performed using the Smart Application as part of
the online configuration process. If you (the installer) are not configuring load balancing, make
sure the rating of the property main fuse/circuit breaker is written on the rear cover of this
manual so that load balancing can be set up by the user.
The main fuse or circuit breaker in the property’s consumer unit should be labelled to state the
maximum load. The load balancing system
must
be set to the same figure (or lower) than that of
the main fuse or circuit breaker.
x
Do NOT set load balancing above the maximum point. Load balancing will not initiate and all
power to the property will be lost if the maximum point is reached.
NOTE:
Load Balancing only limits the power available to the charger. It may still be possible to
exceed the maximum permitted load of the property if too many appliances are used at the
same time.
