•Do not disassemble the MPM 
•Do not attempt to power the MPM from any receptacle except a
properly grounded receptacle with the correct input voltage for the
unit
•Do not place the MPM near water or in environments of excessive
humidity. 
•Do not allow liquid or any foreign object to get inside the MPM
•Do not block air vents of the MPM.
•Do not plug appliances such as hair dryers, fans, heaters, etc. into the
MPM. 
•Do not place the MPM under direct sunshine or close to heat
emitting sources
•The battery should be disconnected from the MPM by unplugging at
its quick connectors when maintenance or service work inside the
MPM is necessary. 
•A certified detachable power supply cord is to be used with this
equipment. For the 250VA models, a type not lighter than SJT
18AWG should be used.
•This MPM is intended for installation in a controlled environment,
indoor area free of conductive contaminants.
•The AC power supply for the MPM should be conveniently near the
MPM and easily accessible –avoid extension cords or temporary
power strips to power the MPM.

Attention:
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC rules. These limits
are designed to provide reasonable protection against harmful
interference in both residential and commercial environments.
This equipment generates, uses, and can radiate radio frequency energy
and if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio and/or
television reception, which can be determined by turning the MPM
equipment on and off, the user is encouraged to try to correct the
interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the MPM and the receiver.
3. Connect the MPM into an outlet on a circuit that is different from
that to which the receiver is connected.
4. Consult the dealer or an experienced radio/TV technician for
assistance.

About the Power and Battery Charger Module
The mobile work platform includes an integrated power system comprised of
two parts:
A. Battery
B. 60601 Isolated Power and Battery Charger Module
•Connected to Wall Power:
–Manages Battery Recharge
–Isolates and limits earth leakage current per 60601
•Disconnected from Wall Power:
–Converts DC power from the Battery to AC power for your
workstation or instrument.
The output AC power of the unit is controlled by a Remote User Interface (RUI)
mounted near the work surface of the cart.
Battery “fuel gauge” and system warning indicators are presented on the RUI
and through an optional software “dashboard” that appears as a small battery
on the Windows taskbar of the workstation computer.
Plug In for Best Battery Health:
The battery in your mobile cart is similar to the battery in your laptop computer.
If it is not charged from time to time, the battery may not have enough charge
remaining when you need it to work. The MPM unit includes an automatic
“jump-start” circuit that will attempt to recover a weak battery. Even so,
following the advice below will help keep your workstation battery working.
Plug in to wall power whenever the battery “fuel gauge” indicates that
battery charge is near empty.
Never leave a cart sit for more than a day with an “empty” battery.
Leaving a battery “empty” for extended periods of time without
recharge will damage the battery.
Make sure the battery is fully charged before putting the cart into
temporary storage (i.e. weeks of non use, disconnected from wall
power).
If the cart is decommissioned or set aside for more than a few weeks of
non-use – smart, Lithium Iron Phosphate Batteries (LiFePO4) should be

put into extended storage mode by qualified Service technicians per
instructions from the battery manufacturer.

Remote User Interface: On/Off Control, Fuel Gauge & Warning Indicators
The Remote User Interface (RUI) is your on/off button and output power
indicator. Pressing the ON/OFF button for more than 1 second will turn the
output on or off. The green Output indicator will be on when output power is
on.
Pressing the Silence button when the MPM is in Battery mode will silence the
audible alarm (audible alarm may be disabled using MPMView software)
The four “battery charge gauge” lights help you know the battery “charge”
level:
oAll 4 lights on – battery full
o“¼” light on Green – battery ¼ full (75% empty).
o“¼” light on Yellow blinking – 1st Low Battery warning –
“minutes remaining”
o“¼” light on Red, blinking – Critical Low Battery warning –
“seconds remaining”.
During recharge each light will blink slowly while that portion of the battery is
being recharged. (For example, 1st light ON, 2nd light blinking means; battery is
between 25% and 50% charged, etc.) Battery is not fully charged until all 4
lights are on without blinking.
Service Required: If either Red or Yellow “warning” lights are ON, some type of
Service is required.
oService NOW: RED Alert -- power down your workstation and
stop using the cart. Turn the cart power OFF and disconnect from
the wall.
oService SOON: YELLOW Warning -- power down your
workstation as soon as you can. Stop using the cart. Turn the cart
power OFF and disconnect from the wall.
