Power Up and Test the Power Supply��

The following table describes the meaning of the power supply LEDs when lit.

1. Connect the AC power cord to the power supply and route the cord to an appropriate AC outlet using the clips provided on the unit.

NOTE: A maximum of four power supplies can be powered from one dedicated 100-120 V, 50/60 Hz, 20-amp feeder or 200-240 V, 50/60 Hz, 10-amp feeder. Use only nonswitched outlets.

2. Plug the cord into the outlet. This powers up the power supply.
3. Check AC operation of the 1145B2 Power Supply by monitoring the LEDs:

PASS: Green and yellow LEDs at the front of the unit should be lit together. Green means the power supply is providing power. Yellow means the battery is being charged. After the battery reaches full charge (maximum of 20 hours), the yellow LED should go out.

FAIL: If either green or yellow LED is not lit after powering up, check the connections. Test the AC outlet. If power is available and the AC power cord and connections are good, replace the power unit.

4. Disconnect the AC plug on the power supply, this activates the DC supply.
5. Check DC (battery back-up) operation of the 1145B2 Power Supply by monitoring the LEDs:

PASS: The red and green LEDs should be lit together. Red means the power supply is on battery back-up.

FAIL: If either green or red LED is not lit after disconnecting AC power, check the connections. If the connections are good, replace the power unit or batteries.

6. Reconnect AC power to the power supply.
