Figure 6-13: P103 Connections
A Note About P103 (Digital Board J3) Connections
You’ll notice that pin 1 of P103 connects to the common connection of Bus 3, which
should have been wired up when the panel strap connections were installed. The same is
true of pin 5, which connects to the common connection of Bus 1. This diagram
illustrates the connection if your gate bus switches choose Gate Bus 1 when the switch
lever is pointed up, and Gate Bus 3 when the switch lever is pointed down.
If, for some reason, your panel legend is reversed (lever up is Gate Bus 3 and lever down
is Gate Bus 1) simply reverse those connections to match.
