3.1 POWER INTERFACES
48VDC Power
Rack-mounted or operating stand-alone, the 4180, 4280, 4000XA, and 4284 accept DC
power input directly from a 48V DC power source which connects to the three position
(return, -48, and ground) terminal block labeled 48V DC on the faceplate. The terminal
block connectors accommodate 10 awg (American Wire Gauge) to 14 awg wire. A
strain-relief clamp is available separately for DC wire stabilization. The actual voltage
range of the 4180, 4280, and 4000XA is 18 through 72 volts inclusive.
The 9480 accepts 48VDC power on a circular connector. The 9480 voltage tolerance is
+/- 10%. The 4284 voltage tolerance is +/- 10%.
24VDC Power
Rack-mounted or operating stand-alone, the 4280 accept DC power input directly from a
24 VDC (nominal) via a circular connector. The circular connector is labeled 24VDC on
the 4280 faceplate. The actual voltage range is 18 through 72 volts inclusive.
AC Power
For this application, a separate AC power supply is available which plugs into a standard
115/240V AC outlet. The power supply has a six-foot cable that terminates with a barrel
connector. The barrel connector plugs into the circular connector labeled 24VDC on the
4280 faceplate. The barrel connector plugs into the circular connector labeled 5VDC on
