RIO Shield-to-
Chassis Jumper
Set the shield-to-ground jumper switch appropriately to specify the repeater’s
relationship to chassis ground (see Fiber Optic Repeater, p. 90 for details).
Connecting
Power
The repeater operates either from 110/220 VAC line power or from 24 VDC. The AC
and DC power connections are located on the back of the panel.
Connecting AC Power
The repeater is supplied with an AC power cable 6 ft (2 m) long for use with either
110/120 VAC or 220/240 VAC single-phase power. The power cable connects to a
socket on the rear panel. Grounding is supplied through the power cable. The AC
power cable is keyed for North American 110/120 VAC power outlets. If necessary,
install a different plug on the cable for the power source at your site.
Turn the power switch OFF and remove the AC power cable from the repeater. Set
the power selector plug to the 110/120 VAC or 220/240 VAC position for the power
source at your site. To do this, remove the power selector plug by prying under its
tab with a small screwdriver. Set the plug to the proper voltage position as shown on
the plug body, then reinsert it. Insert the power cable into the rear panel connector.
Secure the power cable under the strain relief. Plug the cable into the AC power
source.
Connecting DC Power
Your DC power source must supply 1 A at 24 V. Switch the DC source OFF. Connect
the source to DC power terminals, observing the proper polarity. Secure the power
wiring under the strain relief.
