OPERATION WITH AN EXTERNAL BATTERY PACK
For applications where it is required to operate the power supply over long periods, it is possible to
remove the internal battery pack and connect it externally. The battery should be removed as described
above and the internal cable within the
Mag
-03-OCTO-PSU, which is normally connected to the
battery pack input, should be connected directly to the PCB connector. The enclosure lid can then be
replaced and the battery pack can be connected to the charging power input socket of the
Mag
-03-
OCTO-PSU. In this way several battery packs can be used in rotation with charging being carried out
remotely from the
Mag
-03-OCTO-PSU.
