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.
Attaching the Router to a LONWORKS Network
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.
