SEL-351R Falcon Lift-To-Open Enclosure
With Door Open (wiring not shown)
Recloser Control Connections
Available in Lift-To-Open (Figure 16) and Swing-Open
(Figure 17) enclosure options.
The control cable from the recloser attaches at the
bottom of the SEL-351R Falcon enclosure to a standard
receptacle. The wiring from this receptacle continues
into the control itself, with the currents and control
landing on the side-panel terminals.
The 120 or 230 Vac power parallels voltage channel
V1
,
as shown in the retrofit of a traditional installation in
Figure 13. If you order the SEL-351R Falcon with
additional voltage channels
V2
,
V3
, and
VS
, connect true
three-phase voltage and synchronism-check voltage to
the side-panel terminals.
An internal battery monitor/charger provides battery
charging/discharging. Through this battery
monitor/charger the SEL-351R Falcon can monitor
battery voltage. The SEL-351R Falcon puts itself to sleep
if voltage falls to a user-set threshold (or if a user-set
timer times out) after an extended outage.
The SEL-351R Falcon can also be powered with
125 Vdc or 250 Vdc.
