CRITICALPOINT 700/800MHZ BDA/DAS/BBU V3 USER MANUAL 2.13 V3 BDA/MU/RU AND BBU SYSTEM WIRING Comba recommends that every horizontal cable entry to the equipment forms a 'U' before its entry to the equipment. Water on the cable will drip down at the bottom of the loop and will not accumulate at the equipment connectors.
These are shown below in Figure 45. The two DC28V outputs, FOU and AUX, are reserved for Comba FOUs and Annunciator Panels respectively, but can be used for other devices if they are vacant and will not be used in a future expansion of the project.
