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

Power is supplied to the Airmux-200 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:

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-E

AC power to the Airmux-200 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-E:

1. Connect the power cable socket to the power connector on the Airmux-200

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-E

A special IEC 60320 adapter for -48 VDC or -24 VDC power connection is supplied

with the unit.
