SMA FLX Series PLA Option - Manual (Page 7)

Connect the wires as shown in Illustration 1.4. It is
recommended to use multiple ‘+’ terminals to avoid
bundling cables outside the PLA Option for a proper instal-
lation. In this case there is a direct routing from the ‘+’
terminal from the remote control device to the ‘+’ terminal
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.
