b) To prevent battery discharge, do not install the fuse in the S1145B Battery Pack

until the unit is ready to be connected to a Power Unit. Do not store the S1145B

Battery Pack with the fuse installed

7) Operational Test

The following operational test should be done on each unit immediately after

installation.

(The SEI S1145R Power Unit provides a continuous float charge voltage to the

battery. This allows the status indicators on the S1145B to be ON continuously.

The Lucent/ATT 1145 Power Unit provides an intermittent float charge voltage of

2 hours ON and 20 hours OFF. While the Lucent/ATT 1145 Power Unit is in

CHARGE ON mode the S1145B status indicators are ON continuously. When the

Lucent/ATT 1145 Power Unit is in the CHARGE OFF mode the S1145B status

indicators flash every 5 seconds.)

a) Normal Operation: Verify that the Battery Charge Status LED on the S1145B

Battery Pack is either flashing green (Charging), constant green (Fully Charged),

or flashing every 5 seconds. If either of the LEDs are constant red, flashing red or

are not lit consult the troubleshooting section below.

b) Battery Backup Operation: Make sure that the 1145B is properly connected to the

power unit. Disconnect the AC power cord from the power unit. Verify that both

LEDs flash every 5 seconds. The Battery Charge Status LED will indicate a

Power Unit Fault. (Depending on the load and Power Unit it may take several

minutes before the LEDs change state.) If an SEI S1145R Power Unit is being

used, verify that the Power Unit’s LED is constant red. If a Lucent/ATT 1145

Power Unit is being used, verify that the Power Unit’s Output Power On green

LED and On Battery Reserve red LED are lit.

c) Charging Operation: Reconnect the Power Unit AC power cord. Verify that the

Battery Charge Status LED on the S1145B Battery Pack is flashing green

(Charging). If an SEI S1145R Power Unit is being used, verify that the Power

Unit’s LED is constant green. If a Lucent/ATT 1145 Power Unit is being used,

verify that the Power Unit’s green Output Power On LED and yellow Charging

Battery LED are lit.

d) Battery Test: When the battery is fully charged (Battery Charge Status LED

constant green), press the Manual Battery Test switch. Wait five seconds then

verify that the Battery Test Status LED is green. (The Manual Battery Test is only

available when the Power Unit is charging the battery pack. If the Manual

Battery Test switch is pressed when the battery pack is not being charged, but the

battery pack voltage is above 49 volts, the Charge and Test status indicators light

for 2 seconds.)

8) Troubleshooting

a) Battery Pack LEDs Off: If the LEDs on the S1145B Battery Pack are not lit or

flashing every five seconds perform the following checks:

i) Verify that the Power Unit is on. On an SEI S1145R Power Unit, the LED

should be solid green. On a Lucent/ATT 1145 Power Unit, the green Output

Power On LED should be lit.

ii) Check the Battery Connection Cable at the Battery Pack connector and the

Power Unit Connector.

iii) Verify that the Battery Pack fuse is installed.
