The DC power supply has a three-terminal wiring block consisting of a positive (+) terminal, marked 48V; a negative
(–) terminal, marked RTN; and a safety ground, marked GND. The DC supply is designed to be powered by a 48 Volt
DC source. Use 12-gauge to 14-gauge wire to connect the 48-Volt source to the router’s DC power supply. Use
12-gauge to 14-gauge wire for the safety ground.
Note
The RS 3000 does not have an on-off switch. When you connect the power supply
to a DC power source, the router is on.
