Test the device by connecting it briefly to the mains power supply. A green LED indicates that the cable is
connected correctly.
IMPORTANT:
Disconnect the device from the mains power supply after the test is successful.

6.3 Connecting the power outputs

Pay attention to the required cable cross section to suit the current required by the connected equipment.
Connect the cable to the power outputs, making sure that the polarity is correct. Use suitable cable ties for
fastening the cables.
Now carry out another test to determine whether the device works correctly. If the fault LED lights up, then
this may be due to no battery being connected. Ensure that the connected device is supplied correctly with
power. Finally, disconnect the power supply unit from the mains.

6.4 Connecting the backup battery

Use the battery cables supplied for connecting the power supply unit to a battery.
Connect these cables to the connection block and battery.
Please note:
Ensure that the battery connections have the correct polarity:
Use the red cable for the positive terminal (+) and the black cable for the negative
terminal (-).
Connect the power supply unit to the mains power. Ensure that the green LED lights up. Make sure that
the red LED does not indicate any faults.
Now disconnect the power supply unit from the power supply. The green LED should no longer light up.
Check whether the battery provides sufficient voltage and current to the connected devices.
Please note:
Ensure that the battery is charged sufficiently.
If the battery is not charged sufficiently, then charge it before carrying out a new test run.
Please note:
Leave the battery connected to the power supply for a minimum of 30 minutes to start the
charging process.
