Power Input
The Workstation is powered from the AC supply through a standard IEC AC connector . When connected to the AC supply the AC Power
indicator is illuminated . Both the Live and Neutral lines of the main supply are protected using fuses carried in a double fuse holder
located on the AC inlet connector .
Warning: When connected to the AC supply, a three wire (Live, Neutral, Earth) supply must be used. If the integrity of the
external protective conductor in the installation or its arrangement is in doubt, then the Workstation must not be
used.
To isolate the Workstation from AC supply remove the AC connector from the source socket. The Workstation should
A
be positioned to allow access for disconnecting the AC connector.
Battery Supply
The Workstation should normally be operated from the AC power supply . However, in the event of temporary loss of AC power, an
internal power supply will provide approximately 20 minutes of communications only . AC power to the Pumps will be discontinued .
Warning: AC Power should be re-applied as soon as possible as there will be no AC power supplied to the Pumps while the
Workstation is running on the battery.
The Battery indicator illuminates whenever the Workstation is running from the internal battery . When illuminated the Workstation is
operating from internal battery; when flashing the battery power is low and auto power down is imminent . The battery is automatically
charged whenever the Workstation is connected to the AC supply . As the Workstation is designed to operate from the AC power supply it
will only power up when connected to the AC supply .
Caution:
In the event of a power loss, the Workstation with fully charged battery will emit an audible tone every 30 seconds
for the first 14 minutes to alert operators. This audible tone will escalate to every 15 seconds after 14 minutes until
the battery is fully depleted.
If transfer of the Workstation is required, then prior to disconnecting from AC power supply the User must ensure
A
there is sufficient battery power on each of the Pumps.
AC Power Output to Infusion Pumps
The Workstation has its own power distribution circuit to supply AC power to the attached Pumps . For safety, power is not applied to the
MDI tile IEC connector until the Pump is fully attached to the MDI tile . The AC power indicator on the infusion Pump will illuminate when
Pump is powered and charging .
Warning: The MDI tile AC outlet connection is intended only for connection to a Pump. Never attach any other equipment to
the outlet connector.
The Workstation minimises the potential for a high peak in-rush currents when AC power is simultaneously applied to the Pumps . When
the Workstation is initially switched on, or when re-connected to the AC whilst operating from the internal battery, a small delay in the
application of AC power will occur between each MDI tile . This staggers the distribution of AC power to all Pumps and therefore, reduces
the peak in-rush current .
Powering an auxiliary Workstation
Workstations are fitted with an auxiliary AC power outlet connection . However, this should not be used to power a second Workstation . If
a second Workstation is required at the bedside, plug the Auxiliary Workstation directly into a wall AC power outlet .
Note: The safe use of the auxiliary AC power outlet requires management of the
number of Pumps installed so that the system earth leakage current does not
exceed 500uA . For this reason a warning label is placed blocking access to
auxiliary AC outlet . This warning label should not be removed .
