AirHarmony-4000 DC (Integrated External Duplexers) Installation Guide
UGD-D01123 Airspan Commercial and Internal Use 40
Tip: It is good practice to label both ends of the cable to identify which AirHarmony-4000
DC unit it is connected to.
Tip: It is good practice to leave a spare loop of cable (approximately 0.5m). This will allow
for easier wiring and will allow the cable to be re-terminated if necessary in the future.
The power cable is connected to the AirHarmony-4000 DC connector (marked PWR) on the bottom
panel of the unit.

7. Plan the position of the DC power cable run from the AirHarmony unit to the power supply
unit. The DC power cable is offered in various lengths, to fit different deployments.
8. Uncoil the cable and secure the connector just below the AirHarmony unit.
Note: When securing the cable make sure there is no tension on the connector so that it is easy to
disconnect and re-connect for future maintenance actions.
Caution: The internal plastic parts of the mating connector are keyed. Take care to align these by
visual inspection or by gently rotating the connector body until the key way sections align and the
pins go in before tightening the locking ring.
9. Position the pins correctly, the connector is secured to the unit with a locking ring that is
screwed into place. Use firm hand pressure only, the connector has a built in sealing ring.
