Power Up and Test
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 4 power supplies can be powered from 1 dedicated
110 VAC, 20 Amp feeder. Use only unswitched receptacles.
2. Plug the cord into the outlet. This powers up the power supply.
3. Check AC operation of the 1145B 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 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.
4. Disconnect the AC plug on the power supply, this activates the DC supply.
5. Check DC (battery back-up) operation of the 1145B 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.
