Power Source
The installer must provide a compatible power source for the Ellipse system.
The DC
supply connections are located on the front panel of the PoE unit. This is a keyed Buchanan
796864-5 (or equiv.) connector (removable screw-type sector controller block). Dual isolated
floating power supply inputs are provided to accommodate deployments with backup power (e.g.,
A + B battery banks). All power inputs include overvoltage and reverse polarity protection.

Isolation
The installer must provide pluggable sector controller blocks in the cabinet to isolate the
PoE for installation and servicing.
