4. Connecting the Power
Before connecting any cable, the protective earth terminals of the AC/DC
adapter must be connected to the protective ground conductor of the mains
power cord. If you are using an extension cord (power cable) make sure it is
grounded as well.
Any interruption of the protective (grounding) conductor (inside or outside the
instrument) or disconnecting of the protective earth terminal can make this
unit dangerous. Intentional interruption is prohibited.
Connecting Power to an IDU-E
Power is supplied to the FA4800 via an external AC/DC converter, which receives
power from 100–240 VAC source and converts it to -48 VDC.
®
To connect power to the IDU-E:
1. At site A, connect the 2-pin connector of the AC/DC converter to the 2-pin DC
power connector on the IDU rear panel.
2. Connect the AC/DC converter 3-prong plug to a mains outlet.
The unit turns on automatically upon connection to the mains.
The green PWR indicator turns on, and the IDU indicator blinks orange for
approximately 40 seconds during startup. See Normal Indicators section in
Chapter 3.
3. After approximately 20 seconds the ODU starts beeping. The beeps continue
until the ODUs are aligned and the link set up.
4. Wait for approximately one minute, then repeat for Site B.
Connecting Power to an IDU-C
AC power is supplied to the FA4800 through a standard 3-prong plug.
AC power should be supplied via a 1.5m (5 ft) standard power cable terminated
by a standard 3-prong socket. A cable is provided with the unit.
®
To connect AC power to an IDU-C:
1. Connect the power cable socket to the power connector on the FA4800 front
panel.
2. Connect the power cable plug to the mains outlet.
The unit will be turned on automatically upon connection to the mains.
®
To connect DC power to an IDU-C
A special IEC 60320 adapter for -48 VDC or -24 VDC power connection is
supplied with the unit.
