PrintCart Operating Duration
23
Battery Power Operation
When the PrintCart is unplugged from the AC outlet, the power system
automatically switches equipment to inverter power via the automatic transfer
switch.
NOTE: The PrintCart equipment does not have to be turned off and there will
be no significant power interruption to the equipment.
The Battery Powered mode indicator (yellow) on the display indicates that the
battery is now providing power. When running in Battery Powered mode, the
battery system is no longer being charged.
PrintCart Operating Duration
1. Select a printer family (SL4M/T4M or SL5000r/T5000r). Other printer
models are categorized between the two printer families.
2. Within the printer family, select whether a notebook or wireless terminal
will be used.
NOTE: A desktop or compact PC is not the same as a notebook or terminal
due to higher power consumption.
3. Determine the minimum operating time (in hours) at the intersection of the
battery bank row and the equipment column.
NOTE: The operating time span specified is the minimum available at the
end of battery life. This ensures that operational requirements will be
met as the battery capacity declines by approximately 30% as the
battery ages.
NOTE: Frequently charging the PrintCart prior to reaching maximum
allowable discharge will maintain battery life and delay declining
capacity.
