2. (Optional) Install EPO switch
If you wish to install an EPO switch: Note that the EPO connections have a preinstalled wire that
shorts the EPO+ and EPO-. Remove the preinstalled wire and connect the EPO switch; then turn
the EPO switch to its “Closed” position (Normal Status) and continue to the next step
DO NOT Set the EPO switch to “Open” (Cut Off Status)
The EPO switch can be installed at a remote location; note that the voltage-drop caused by the
wiring must be <14V
The EPO function is triggered from a relay and this relay is energized by the battery or the
charger; if the battery is over-discharged, then the EPO function may not work properly
If you do not wish to use an EPO switch, then continue to the next step directly (do not remove
the preinstalled shorting wire)
3. (Optional) Install Annunciator: See Annunciator BBU V(x) to Annunciator Panel Wiring Diagram.
4. Wire dry contact alarms and external alarms
Dry contact alarms default configurations:
ALM 1: AC Fail
ALM 2: Battery Low
ALM 3: Charger Fail
ALM 4: EXT ALM 1
ALM 5: EXT ALM 2
ALM 6: EXT ALM 3
ALM 7: EXT ALM 4
If you need to define different alarms, it can be done using the WEBOMT tool.
Note that the BBU dry contact alarms provide both Normally Open and Normally Closed configurations;
refer to the picture below for wiring instructions
Alarms from external devices (BDA, AMS, etc.) can be tied into BBU EXT ALMs so they can be
annunciated using the LEDs from the BBU front panel. In order to match the order of the BBU
Annunciator LEDs:
EXT ALM 1 shall tie to Signal Booster Fail (from BDA)
EXT ALM 2 shall tie to Antenna Malfunction (Normally from BDA)
EXT ALM 3 shall tie to System Component Failure (Normally from BDA or AMS)
EXT ALM 4 not defined

Rev 1.11 – 01-21-2021
By default, the EXT ALMs work with Normally Open dry contact alarm wiring; the dry contact alarm type
(Normally Open or Normally Closed) can be configured using the WEBOMT tool. The two wires from dry
contact alarms can be tied to EXT ALMs positive and negative termination block – the polarity does not
matter.
5. Install AC input wires
Primary Lead / Earthing Lead: min. 14 AWG (cable is not included)
6. Install wires for load
BBU provides 3 sets of terminations for loads
All 3 loads share the same power being supplied by the charger or batteries
Note: All Comba BDAs, MUs, RUs, and other -48V products come with a power cable.

Rev 1.11 – 01-21-2021
7. Install batteries, battery jumpers and connector caps
The batteries need to be installed in the straight up position as indicated in the picture (so that when the
BBU is mounted to the wall, the battery posts are on top/pointed towards the ceiling).
Partially pull out the batteries to connect all the positive terminals first, then push the batteries
back in and connect the negative terminals.
For safety, after installing the batteries always connect the black negative wire as the last step;
for battery removal, always disconnect the black negative wire as the first step.
NOTE: If provided with the unit, discard the battery support bar that was originally included in
the unit – it is no longer required to be installed.
8. Switch on both breakers; the BBU will boot up in 2-3 minutes and start working
Software Instructions:
The BBU should now be running; it will be configured to the default settings. To change the settings, or review
product identification information, you can log into the unit using the optional WEB interface (WEBOMT). After
logging in, the WEBOMT will provide the following information and options to you:
Unit information: Serial Number, Firmware versions and upgrade etc.
Unit status: alarms, charging status, temperature etc.
Customize alarming
WEBOMT Login:
Change IP address manually to 192.168.8.xxx/255.255.255.0 (DO NOT use 192.168.8.101)
Or wait for the IP address to be automatically assigned by the BBU
Use 192.168.8.101 in the browser to login
(Comba recommends using Chrome in Incognito Mode, or Firefox in private mode)

In this state, the load does not have backup from the batteries.
- Output Voltage:
o The voltage that the BBU provides to the loads
- Charging Current:
o The current draw while the BBU is charging the batteries
- Battery Status:
o Cycle charging: BBU is using high current while charging the battery
Refer to Setting page: <Cycle Charge Voltage>

Rev 1.11 – 01-21-2021
o Cut off: Either (1) battery voltage is lower than the Cut Off Threshold so they have been cut
off from the system to ensure they can still be recharged, or (2) batteries have not properly
charged, leading to the BBU to cut them off to ensure no battery or system damage occurs.
The unit might ship with the batteries in cut off status due to no batteries connected during
factory firmware flash.
Refer to Setting page: <Cut Off TH>
o No battery: Battery is not connected
- Battery Voltage:
o The voltage of the batteries
- Alarm Status:
o Refer to Appendix - Alarm section
Settings:
NOTE: After setting up a new unit or upgrading the firmware, always verify that all the
parameters in this page are set to default values; always contact Comba technical support
PRIOR to changing any of the parameters
- Low Voltage TH: default = 47.3V
o Define the minimum percentage the battery capacity (e.g. 30%), and the <Battery
Low> alarm will be triggered when the remaining battery capacity reaches 30%
- Cut Off TH: default = 44V
o Battery supply to the loads will be cut off if the battery voltage is lower than the
desired threshold; the charger will try to charge the batteries when AC is restored,
but it is not guaranteed that the batteries can be charged if the batteries are over-
discharged to the point of being damaged.
- Over Temperature TH: default = 50degC
o Over temperature alarm threshold
- Battery Connection Detection: The system will check once during each 24-hour period to
verify that all batteries are connected.
- Panel NO: See Annunciator Panel Manual.
NOTE 1: IF THE BBU DOES NOT SEE A LOAD (i.e., the BDA or fiber DAS devices is powered
down, or has been removed for some reason), the Battery Connection Detection alarm may
trigger. To prevent this, we recommend disabling the Battery Connection Detection alarm
until the BDA or fiber DAS device has been powered up or has been re-installed.

Rev 1.11 – 01-21-2021
- External Alarm setting page
o Users can define whether the external alarm is a Normally Open or Normally Closed
alarm from an external device (such as the dry contact alarms from BDA), so the
external alarms will be triggered accordingly
- Alarm Enable/Disable page
o Users can enable or disable the listed alarms
- Alarm Detect Duration
o Users can define a time interval to specify the amount of delay before an alarm is
triggered; each number set here indicates 10 seconds (e.g. 5 = 50s, 10 = 100s, etc.) –
the system will monitor the alarm status during this duration and then will trigger
the alarm after the specified delay time.
Management:
Users can obtain information and perform tasks:
- Get device S/N, temperature, Firmware version
- Upgrade firmware
o After upgrading the firmware, the user must recheck all dry contact alarm settings to verify no
changes to these have been made by the upgrade
