Installation
Connect the wires as shown in Illustration 1.4. It is

1 1
lation. In this case there is a direct routing from the '+'

of the PLA Option. As an alternative, it is possible to
bundle multiple wires outside of the PLA Option and
connect them to only 1 common '+' terminal. See
Illustration 1.5.
