5.5 Connecting the DC Power Cable to AirHarmony-
4200 DC
Danger: Hazardous voltage! Before working, ensure that the power is removed from the
power connection cables. When the system is powered on, do not touch the power
terminals.
Tip: It is good practice to label both ends of the cable to identify which AirHarmony-4200
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-4200 DC connector (marked PWR) on the bottom
panel of the unit.
Power Input – DC
Caution: Verify the Power Cable Polarity is correct according to the unit’s specification.
Caution: It is important that the power connector is attached at the correct end or damage to the
connector/equipment will result.
Note: Check Power Supply for proper polarization.
Note: Airspan supplies two (2) types of cable, either black wire and white wire cable or black wire
and blue wire cable. The cables’ specs are identical only the colors are different.
