Check AC operation of the 1145B2 Power Supply by monitoring the LEDs:
PASS : Green and yellow LEDs at 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 twenty 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.
Disconnect the AC plug on the power supply, this activates the DC supply.
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.
Reconnect AC power to the power supply.
Install cross-connect jumpers to wire from the unit (the label shows polarity) to Pins 7
and 8 of the appropriate information outlet. Route the wires through the clip provided on
the unit. If a red LED is on, see
