6) Power-up and Test

a) Power the S1145R by plugging the AC power cord into an unswitched outlet.

b) Verify that the LED on the Power Unit is constant green. If it is not, check the

AC power cord connection at the Power Unit and the power outlet.

c) Verify that the green power LEDs on the NT1s connected to the 1146B

Distribution Unit are on. If none of the NT1s are powered, check the connection

of the Distribution Unit Power Cable Adaptor at the Power Unit and the

Distribution Box. If an individual NT1 is not powered, check the connection at

the 1146B punchdown block.

d) Verify that the Battery Charge Status LED on the S1145B Battery Pack is either

flashing green (Charging) or solid green (Fully Charged). If it is not, check the

connection of the Battery Connection Cable at the Power Unit and the Battery

Pack and verify that a good fuse is installed in the fuse holder on the right side of

the Battery Pack.

a) Unplug the AC power cord on the Power Unit. Verify that the LED on the Power

Unit is constant red and the LEDs on the S1145B Battery Pack are off. Verify

that the NT1s are still powered. (Under very light load conditions, it may take

several minutes before the LEDs change state. The Battery Charge Status LED

on the Battery Pack will display constant or flashing red to indicate a Power Unit

Fault.)

e) Reconnect the AC power cord on the Power Unit. Verify that the LED on the

Power Unit is constant green and the Battery Charge Status LED on the S1145B

Battery Pack is flashing green (Charging).
