Applying Power to the MPR-50 Multi-Port Router

Connect earth ground, if available, to terminal 3. Then connect 9–28VAC (40–70Hz)

or 9–35VDC power to terminals 1 and 2—the power terminals are polarity-
insensitive so the polarity of the DC input is unimportant. The green Power LED

will illuminate to indicate the unit is powered and the Status LEDs will begin

operating within seconds.

Connect the screw terminals marked Router 1 through Router 5 to the desired

channels. Router 1 is for the TP/XF-1250 channel, while Routers 2–5 are for the

TP/FT-10 channels. TP/XF-1250 and TP/FT-10 channel wiring is polarity-

insensitive, and the TP/FT-10 connections are link power compatible. Any router

that is not going to be used may be left unconnected.
