Wire the 1146B1 Power Distribution Unit
It may be better to wire endpoints to the 1146B1 while power from the 1145B1 is
on. This way, a red light emitting diode (LED) on the distribution unit lights if you
connect its associated circuit to shorted building wiring or to a shorted terminal.
on. This way, a red light emitting diode (LED) on the distribution unit lights if you
connect its associated circuit to shorted building wiring or to a shorted terminal.
1.
Install cross-connect jumpers to wire from the Distribution Unit (the label
shows polarity) to Pins 7 and 8 of the appropriate information outlet.
Route the wires through the clip provided on the unit. If a red light
emitting diode (LED) is on, see the next section
shows polarity) to Pins 7 and 8 of the appropriate information outlet.
Route the wires through the clip provided on the unit. If a red light
emitting diode (LED) is on, see the next section
Reset light emitting
diodes (LED) on Power Distribution Unit
. The following illustration shows
a typical connection.
2.
Mark lead destination on the label next to each connector on the
Distribution Unit. Also mark the Unit Number and Connectivity
information on the label.
