On-Grid Preparation

The intended application and use of the SP PRO must be well understood to allow the SP PRO to be
appropriately connected to the installation. Depending on whether the entire installation load or only essential
loads are to be battery backup protected when consumer mains is disrupted, will depend on how the SP PRO
is wired into the switch board.
The following is a single line diagram in a similar format to AS4777.1 figure 3. This diagram indicates the
customer circuits some of which are battery back-up protected, some which are not.

The diagram also shows locations of various isolating switches, using similar terms to AS4777.1 figure 3.
