Observing polarity, connect the leads from the 24 Vdc power supply to the A
(+V) and C (– COM) terminals, respectively. While using a small bladed
screwdriver in the slot above the terminal to pry open the terminal clamp,
insert the stripped end of the power lead into the terminal and remove the
screwdriver to secure it. The recommended wire size is 14 AWG stranded
cable. The acceptable wire size range is 24 AWG minimum to 14 AWG
maximum.
(Note that the Repeater Adapter does not have a power switch, so it is
powered whenever the power supply is turned on.)
