Add an external breaker to the AC input to protect the MPS Ultra from inrush
current as shown in the table below:
Number of Power
Modules (single shelf)
Recommended Breaker Rating (per shelf)
100-120VAC Input
200-240VAC Input
Two Power Modules
25A
15A
Three Power Modules
40A
20A
Four Power Modules
40A
25A
Example: 3.5kW MPS Ultra at 240VAC input having 2 modules on the top shelf
and 3 modules in the bottom shelf will require a 15A breaker on the top shelf AC
input and a 20A breaker on the bottom shelf AC input.
OPERATION (Front Panel)
Switch on the external AC power source circuit breaker, and check that the green
POWER LED is lit on each Power Module, and that the ICM front graphic display
is lit.
The MPS Ultra will start up and operate at the factory default settings when AC
power is connected, generally requiring no other set up or adjustment for basic
operation.
Use the front graphic display and four interface buttons on the Intelligent Control
Module (ICM) to monitor the supply operation and to make changes to settings
such as output voltage, current limit, and battery Low Voltage Disconnect points.
The display will go off after approximately 60 minutes of no use, and can be re-
activated by momentarily pressing any of the front control buttons.

System Status Screen
The ICM Interface panel consists of the following elements:
System Display screen:
Default System Status screen shown in Fig 9 displays the
system output voltage, the AC input voltage, and the total output current.
(Numerically, and with a graphical indication of relative magnitude of system
output current level) The screen will also show any active alarm conditions, and
