1INSTALLATION
1.1 BDA NG WALL MOUNTING
Remove the mounting bracket from the BDA.
Drill four holes on the wall/plywood using the position of four holes on the mounting rack as a guide.
Install the Mounting Rack to the wall.
Hang the equipment and secure the enclosure to the mounting rack.
Figure 1: BDA NG Wall Mounting
1.2 BBU NG WALL MOUNTING
Drill four holes on the wall/plywood using the position of holes from battery backup unit as a guide.
Install the battery backup unit (without battery) to the wall.
Figure 2: BBU NG Wall Mounting

1.3 BATTERY INSTALLATION
Slide the battery into the chassis.
Make sure the <AC breaker> and <Battery Breaker> are both OFF. Connect the TWO BLACK BBU/battery wire to
the positive (+) battery terminal and the TWO BLUE BBU/battery wire to the negative (-) battery terminal.
Install the battery retaining bracket and secure with four screws.

1.4 BDA AND BBU CONNECTION
The complex cable connects the BDA NG and BBU NG is provided with BBU NG, as Figure 4 shows.
Make sure both AC (POWER) switch and DC (Boot w/o AC) switch are OFF in the BDA, as Figure 5 shows.
Connect the <connectorized end> to the BBU as Figure 7 shows, then run the cable through a 3/4” knockout
(recommended) from the BBU to a 3/4” knockout on the BDA, then into the BDA for connection. The cable can
run through a conduit or from liquid tight connectors for water proofing.
Connect to the BDA as below:
.1 (AC) Black to L
.2 (AC) White to N
.3 (AC) Green/Yellow to GND
.4 (DC) Brown to BATT+
.5 (DC) Blue to BATT-
.6 (Battery COMM.) Blue/White to BATT B
.7 (Battery COMM.) Red/White to BATT A
.8 Black/White wire is reserved

1.5 AC INPUT AND OTHER CONNECTIONS FOR BBU
Make sure the <AC breaker> is OFF in the BBU
Connect the AC input into the BBU.
The EPO should be either connected to an external EPO switch or shorted with a jumper (as shown in Figure 8).

Ground Connection
To ensure safe operation of the product, a ground (earth) connection is required. For single phase AC power source, the
product must be grounded by connecting the “earth wire” of the power cord to the ground terminal of the AC supply.
For operating this product with DC power system (such as rectifiers), the product should not be connected to power
systems that switch open the return lead because the return lead could function as the ground (earth) connection for
the equipment.
Protective Ground Connection
The enclosure must be grounded securely by connecting a copper wire (CSA 16mm2) to the grounding terminal on the
equipment/rack, and the other end to a protective ground (i.e., building earth point). An internationally acceptable color
code of the ground connection wire is green/yellow.
Such a ground connection implements the “Protective Ground Connection” and must be connected to the equipment at
the designated ground point. In general, do not connect the supply before establishing an adequate ground (earth)
connection.
Construct the ground wire and use appropriate crimp connectors where necessary. Locate and connect the equipment
grounding terminal to a protective ground (i.e., building earth point).

2.2 ALARMS CONNECTIONS
BDA NG has 8 dry contact outputs, each one supports either Normally Open or Normally Closed operations.
The alarms to trigger any of the dry contacts can be configured in the software.

BDA NG has 5 external alarm inputs, it takes dry contact alarms from external devices and can be setup in the
software to be either Normally Open to trigger or Normally Closed to trigger.
The external alarm 5 is pre-configured as “Door Open Alarm”.

3SYSTEM TURN UP PROCEDURE
Confirm the connections and polarities for all AC and DC Connections.
Wake up the Battery:
Momentarily press the RESET button located on top of the LiFEPO4 battery to wake it up approximately 3
seconds. Once the first SOC (State of Charge) LEDs begins to illuminate, release the RESET button immediately
(NOTE: Holding the RESET button longer than approximately 5 seconds will cause the battery to go back into
sleep mode. If this occurs, repeat the step to “wake-up” the battery by momentarily pressing the RESET button)
Turn on the system: (no sequence required)
.1 AC Breakers in the BBU
.2 Battery Breakers on the battery
.3 Turn on AC (POWER) Switch in the BDA
The DC (Boot w/o AC) switch in the BDA is used to turn on the system when there is no AC source so the system
can bootup with Battery. It is recommended to leave it OFF under normal conditions.
